- The Firepower Management Center Configuration Guide incorrectly states that Cisco does not recommend enabling more than one non-SFRP IP address on a 7000 or 8000 Series device high availability pair's routed or hybrid interface where one SFRP IP address is already configured. The system does not perform NAT if a 7000 or 8000 Series device high availability pair experience failover while in standby mode.

- The Firepower Management Center Configuration Guide does not reflect that in a multidomain deployment, when you create a DNS policy, the Descendant Whitelists for DNS rule and Descendant Blacklists for DNS rule are disabled by default. You can enable each rule by editing them.

content is updated more regularly than the online help.

Features and Changed Functionality Introduced in Previous Versions

Functionality described in previous versions may be superseded by other new functionality or updated through resolved issues. The following features and functionality were introduced in previous versions:

Version 6.0.1

Fully Integrated, Threat-Focused Next-Generation Firewall

Most next-generation firewalls (NGFWs) focus heavily on enabling application control, but little on their threat defense capabilities. To compensate, some NGFWs try to supplement their first-generation intrusion prevention with a series of non-integrated add-on products. However, this approach does little to protect your business against the risks posed by sophisticated attackers and advanced malware. Further, once you do get infected, they offer no assistance in scoping the infection, containing it, and remediating quickly.

The Cisco Firepower™ Next-Generation Firewall (NGFW) is the industry’s first fully integrated, threat-focused NGFW. It delivers comprehensive, unified policy management of firewall functions, application control, threat prevention, and advanced malware protection from the network to the endpoint.

Firepower Threat Defense

The Firepower Threat Defense software package can be deployed on Cisco Firepower 4100 and 9300 appliances to provide a performance and density optimized NGFW security platform for Internet edge and other high-performance environments. Firepower Threat Defense functionality added in this release includes device and interface management, routing, NAT, and device high availability, in addition to support for the full Firepower NGIPS offering.

This release introduces support for Firepower Threat Defense on the Firepower 4100 Series and the Firepower 9300, as well as on the ASA 5506-X, ASA 5506H-X, ASA 5506W-X, ASA 5508-X, ASA 5512-X, ASA 5515-X, ASA 5516-X, ASA 5525-X, ASA 5545-X, and ASA 5555-X.

Firepower 4100 Series

Stop more threats with our fully integrated next-generation firewall (NGFW) platform. The Firepower 4100 Series’ 1-rack-unit size is ideal at the Internet edge and in high-performance environments. It shows you what is happening on your network, detects attacks earlier so you can act faster, and reduces management complexity.

Firepower 9300 Series

This carrier-grade platform is ideal for data centers and other high-performance settings that require low latency and high throughput. Deliver scalable, consistent security to workloads and data flows across physical, virtual, and cloud environments. With tightly integrated services, the Firepower 9300 lowers costs and supports open, programmable networks. The Firepower 9300 Series offers up to 1.2 Tbps clustered throughput, 10/40/100 Gb network interfaces, up to 57 million concurrent connections with application control, and 500,000 new connections per second. Available features and services include a stateful firewall, application visibility and control, NGIPS, advanced malware protection, reputation-based URL filtering, and DDoS mitigation.

Version 6.0

Expanded Threat Protection

URL and DNS-based Security Intelligence

New Security Intelligence feeds based on URLs and Domain Name System (DNS) servers are provided to enhance the existing IP-based Security Intelligence capability. Currently, IP-based intelligence is used to control access to known malware, phishing, command & control, and Bot sites. New attack methods designed to defeat IP-based intelligence (e.g., fast flux) abuse DNS load balancing features in an effort to hide the actual IP address of a malicious server. While the IP addresses associated with the attack are frequently swapped in and out, the domain name will rarely change. The URL-based intelligence will supplement the IP-based intelligence in addressing this kind of attack, and the DNS-based intelligence will help identify known DNS servers that are complicit in these kinds of attacks. Access control policies can be created using these new intelligence feeds and new dashboards provide visibility and analysis. In addition, both URL-based and DNS-based Security Intelligence events will also feed in to the Indications of Compromise (IoC) correlation feature. These new feeds are provided through regular updates from the Cisco Talos Security Intelligence and Research Group and, like the IP-based Security Intelligence feature, are part of the base product and do not require a separate license.

DNS Inspection and Sinkholes

The same way that attackers use the SSL protocol to hide their activity, attackers use the DNS protocol with the same intentions. For that reason, and as another way to address fast flux-type attacks, the Firepower system provides the ability to intercept DNS traffic requests and take appropriate action based on the policy setting. A DNS policy allows for requests to known command & control, spam, phishing, etc., sites to be blocked, to return a Domain Not Found message, or have the traffic directed to a pre-configured sinkhole. This last option routes the traffic directly through the Firepower managed device and gives information about the endpoint that could result in an IoC alert.

Enhanced Network Visibility and Control

SSL Decryption for Cisco ASA with FirePOWER Services Managed Via ASDM

Cisco’s next-generation firewall (NGFW), Cisco ASA with FirePOWER Services, now has the ability to locally manage SSL communications and decrypt the traffic before performing attack, application, and malware detection against it. This is the same capability we introduced in Version 5.4 for Cisco’s Firepower next-generation IPS (NGIPS) appliances. SSL decryption can be deployed in both passive and inline modes, and supports HTTPS and StartTLS-based applications (e.g., SMTPS, POP3S, FTPS, IMAPS, TelnetS). Decryption policies can be configured to exert granular control over encrypted traffic logging and handling, such as limiting decryption based on URL categories to enforce privacy concerns. It also provides the ability to block self-signed encrypted traffic, or on SSL version, specific Cipher Suites, and/or unapproved mobile devices.

Support for OpenAppID-Defined Applications

OpenAppID is Cisco’s open source, application-focused detection language that enables users to create, share and implement new application detection signatures for custom, localized, and cloud applications, without being dependent upon a NGFW vendor’s release cycle or roadmap. In Version 6.0, the Firepower application detection engine that identifies and controls access to over 3,000 applications has been enhanced to recognize OpenAppID-defined applications. In the same way that Snort was an effort to open source the intrusion detection game, OpenAppID is a way to open source the application detection game. Support for OpenAppId-defined applications demonstrates Cisco’s commitment to the open source initiatives and the flexibility that it provides to our customers.

Captive Portal and Active Authentication

In order to provide better visibility in mapping users to IP addresses and their associated network events, the Captive Portal and Active Authentication feature can be configured to require users to enter their credentials when prompted through a browser window. The mapping also allows policies to be based on a user or group of users. This feature supplements the existing Sourcefire User Agent (SUA) integration with Active Directory to address non-Windows environments, BYOD users, and guests.

Note: Cisco ASA with FirePOWER Services running ASA Version 9.5(2) and ASA Version 9.5(3) does not support the Captive Portal and Active Authentication feature.

Integration with Cisco Identity Services Engine (ISE)

The integration with Cisco ISE enhances the user identity data available to the system to use in analysis and policy control. By subscribing to Cisco’s Platform Exchange Grid (PxGrid), the Firepower Management Center is able to download additional user data, device type data, device location data, and Security Group Tags (SGTs —a method used by ISE to provide network access control). Beyond the added visibility into the users on your network, this data is also actionable intelligence because it extends the control you can provide by creating policies based on SGTs, or on device type, or any of the other information provided by ISE.

Note: In Version 6.0, you cannot use ISE to automatically quarantine an infected endpoint. This functionality will be added in a later release.

Improved Threat Defense Against Advanced Persistent Threats

Local Malware Checks

This feature provides the ability to identify popular/common malware directly on the Firepower appliance, and reduces the need to send files for dynamic analysis (sandboxing), either in the cloud or on-prem (see Intergration with AMP Threat Grid). Using high-fidelity ClamAV signatures, files whose SHA-256 lookup return a disposition of Unknown will be analyzed locally on the Firepower appliance to identify common characteristics associated with malware, reducing the need for dynamic analysis.

File Property Analysis

Because certain file types support nested content that can be used to hide malware, this feature provides local analysis of files to determine the viability of malware hidden within. For example, a PDF file can contain different types of files nested inside the file. A file composition report is then run that identifies if nested data exists within the file, what file types those nested files represent, and how likely each nested file is to contain malware. Based on this information, you can choose whether or not to send the file on for dynamic analysis.

Integration with AMP Threat Grid

Cisco’s acquisition of ThreatGrid in June 2014 increased our abilities in helping our customers address advanced persistent threats, and that technology has now been fully integrated in Firepower v6.0. AMP Threat Grid now provides our sandboxing capabilities in the cloud when using our AMP for Firepower option. Files sent to the cloud for dynamic analysis are securely analyzed and correlated against hundreds of millions of other analyzed malware artifacts to provide a global view of malware attacks, campaigns, and their distribution. Detailed reports identify key behavioral indicators and determine threat scores for faster prioritization and recovery from advanced attacks.

In addition, we have greatly expanded the file types we support for automatic dynamic analysis from just executable files to include PDF and Office documents.

Expanded Management Functionality

Multiple Domain Management

To address the service provider market which must manage separate customer environments, as well as enterprises with acquisitions (resulting in overlapping IP addresses) or geographic business units that need to be managed separately, the Firepower Management Center now has the ability to create multiple management domains. These domains (up to 50) enable separate management environments and are administered using granular role-based access control (RBAC). Each domain provides separate event data, reporting, and network maps.

Policy Hierarchy and Inheritance

To support multiple domain management and make policy administration more efficient, Version 6.0 provides the ability to create a hierarchy of policies. Global policies (e.g., access control) can be established that will apply to all management environments. A policy hierarchy can then be constructed underneath the global policy level to represent different environments, different companies, different business units, or different parts of the organization. Each of these policy environments will inherit the policies of the hierarchy above it, allowing for more consistent and efficient policy management.

Expanded ASDM Management Availability

Cisco’s Adaptive Security Device Manager (ASDM) is the local management feature for Cisco ASA with FirePOWER Services. It was introduced as part of the Cisco ASA 5506-X, ASA 5508-X, and ASA 5516-X appliances. With Firepower v6.0, ASDM is now available on the remaining Cisco ASA with FirePOWER Services appliances (ASA 5512-X / ASA 5515-X / ASA 5525-X / ASA 5545-X / ASA 5555-X / ASA 5585-X).

- You cannot compare policies on the following pages: the NAT Policy page, the Platform Settings page, and the SSL Policy page.

- Version 6.0 does not support AMP for Firepower signature lookups with the private AMP cloud. In Version 6.0, the system automatically submits SHA-256 signatures to the public AMP cloud. If you have a private AMP cloud and are receiving events from endpoints, the Version 6.0 Firepower Management Center will continue to receive those events without any additional changes to your configuration.

- Syslog messages for connection events now populate information for the following fields: HTTP Referrer, User Agent, and Referenced Host.

- Version 6.0 does not support Discovery Event Health Monitoring.)

- You can now edit Automatic Application Bypass (AAB) settings on Cisco ASA with FirePOWER Services.

Use the Firepower Management Center to back up event and configuration data for itself and the devices it manages. For more information on the backup and restore feature, see the Firepower Management Center Configuration Guide.

Version 6.0.1.1 does not support AMP for Firepower signature lookups with the private AMP cloud. In Version 6.0, the system automatically submits SHA-256 signatures to the public AMP cloud. If you have a private AMP cloud and are receiving events from endpoints, the Version 6.0 Firepower Management Center will continue to receive those events without any additional changes to your configuration.

Note: The Firepower Management Center purges locally stored backups from previous updates. To retain archived backups, store the backups externally.

Caution: Although the configuration options for Firepower Management Center high availability appear in the Integration page of the user interface, high availability is not supported for Firepower Management Centers in this release. Do not attempt to place Firepower Management Centers into high availability.

Disk Performance Management and Longevity on Firepower 4100 Devices

If you have a Firepower 4100 series device running Firepower Threat Defense, we recommend that you update to the latest version of the software (and at least Version 6.1.0) to take advantage of software updates that enhance disk management performance and disk longevity.

Traffic Flow and Inspection During the Update

When you update your sensing devices, traffic either drops throughout the update or traverses the network without inspection depending on how your sensing devices are configured and deployed: routed or transparent, inline vs passive, bypass mode settings, and so on. We strongly recommend performing the update in a maintenance window or at a time when the interruptions will have the least impact on your deployment.

Note: When you update 8000 Series clusters or stack pairs, the system performs the update one device at a time to avoid traffic interruption. When you update clustered Cisco ASA with FirePOWER Services devices, apply the update one device at a time, allowing the update to complete before updating the second device.

This section discusses traffic behavior during the following update stages:

- The update itself, including related reboots

- FXOS updates on clustered Firepower Threat Defense, devices

- Configuration deployments after the update

Network traffic is interrupted briefly at two points:

- At the beginning of the update process, as link goes down and up (flaps) and the network card switches into hardware bypass.

- After the update finishes as link flaps and the network card switches out of bypass. Inspection resumes after the endpoints reconnect and reestablish link with the device interfaces.

The hardware bypass option is not supported on nonbypass network modules on Cisco ASA with FirePOWER Services on 8000 Series devices, or SFP transceivers on 7000 Series.

Traffic Behavior When Updating FXOS on Clustered Firepower Threat Defense Devices

Updating FXOS reboots the chassis, which drops traffic in a clustered environment until at least one module comes online.

Traffic Behavior During Configuration Deployment

During the upgrade process, you deploy configurations either twice (standalone devices) or three times (devices managed by the Firepower Management Center). When you deploy, resource demands may result in a small number of packets dropping without inspection. In most cases, the deployment immediately after the upgrade restarts the Snort process. During subsequent deployments, the Snort process restarts only if, before deploying, you modify specific policy or device configurations that always restart the process when deployed.

The following table describes how different devices handle traffic during Snort process restarts.

Audit Logging During the Update

When updating appliances that have a web interface, after the system completes its pre-update tasks and the streamlined update interface page appears, login attempts to the appliance are not reflected in the audit log until the update process is complete and the appliance reboots.

Time and Disk Space Requirements for Updating to Version 6.0.1.1

The table below provides disk space and time guidelines for the Version 6.0.1.1 update. Note that when you use the Firepower Management Center to update a managed device, the Firepower Management Center requires additional disk space on its /Volume partition.

restart the update or reboot your appliance at any time during the update process. Cisco provides time estimates as a guide, but actual update times vary depending on the appliance model, deployment, and configuration. Note that the system may appear inactive during the pre-checks portion of the update and after rebooting; this is expected behavior.

The reboot portion of the update includes a database check. If errors are found during the database check, the update requires additional time to complete. System daemons that interact with the database do not run during the database check and repair.

Note: The closer your appliance’s current version to the release version (Version 6.0.1.1), the less time the update takes.

Installing the Update

Before you begin the update, you must thoroughly read and understand these release notes, especially Supported Platforms and Compatibility and Before You Begin: Important Update and Compatibility Notes.

.

For minimum Firepower System version requirements, see Firepower Version Requirements for Updating to Version 6.0.1.1. To update your appliances, see the guidelines and procedures outlined below:

- Updating Firepower Management Centers

- Updating Managed Devices and Cisco ASA with FirePOWER Servicess

- Updating Firepower Threat Defense Devices

reboot or shut down your appliances during the update until you see the login prompt. The system may appear inactive during the pre-checks portion of the update; this is expected behavior and does not require you to reboot or shut down your appliances.
When to Perform the Update

Because the update process may affect traffic inspection, traffic flow, and link state, Cisco strongly recommends you perform the update in a maintenance window or at a time when the interruption will have the least impact on your deployment.

Installation Method

Use the Firepower Management Center’s web interface to perform the update. Update the Firepower Management Center first, then use it to update the devices it manages.

Order of Installation

Update your Firepower Management Centers before updating the devices they manage.

Firepower Threat Defense is new for Version 6.0 of the Firepower System. For information about installing the Version 6.0.1.1 Firepower Threat Defense image on supported ASA models, see the Cisco Firepower Threat Defense Quick Start Guide.

Installing the Update on Paired Firepower Management Centers

Updating Firepower Management Center in a high availability pair is not supported in Version 6.0. In order to update Firepower Management Centers in a high availability environment, you must break the pair and update each Firepower Management Center individually. In order to update to Version 6.0.1.1, you must break the high availability pair.

Caution: Although the configuration options for Firepower Management Center high availability appear in the Integration page of the user interface, high availability is not supported for Firepower Management Centers in this release. Do not attempt to place Firepower Management Centers into high availability.
Installing the Update on High Availability Devices

When you install an update on Firepower Threat Defense devices in a high availability pair, the system updates the devices one at a time. When the update starts, the system first applies it to the secondary device, which goes into maintenance mode until any necessary processes restart and the device is processing traffic again. The system then updates the primary device, which follows the same process.

When you update a Cisco ASA with FirePOWER Services high availability pair, apply the update one device at a time, allowing the update to complete before updating the second device.

Installing the Update on Stacked Devices

When you install an update on stacked devices, the system performs the updates simultaneously. Each device resumes normal operation when the update completes. Note that:

- If the primary device completes the update before all of the secondary devices, the stack operates in a limited, mixed-version state until all devices have completed the update.

- If the primary device completes the update after all of the secondary devices, the stack resumes normal operation when the update completes on the primary device.

When you update clustered Firepower Threat Defense devices, the primary device completes the update after all of the secondary devices. You must reboot the device cluster before you deploy configuration from the Firepower Management Center.

Caution: Prior to updating a Firepower 9300 Firepower Threat Defense device to Version 6.0.1, you must update the device to FXOS 1.1.4. The device will experience a disruption in traffic during the update. This is expected behavior.
After the Installation

After you perform the update on either the Firepower Management Center or managed devices, you must redeploy your configurations. For more information, see the Firepower Management Center Configuration Guide.
.
There are several additional post-update steps you should take to ensure that your appliances are performing properly. These include:

- verifying that the update succeeded

- making sure that all appliances in your deployment are communicating successfully

- updating to the latest patch for Version 6.0.1.1, if available, to take advantage of the latest enhancements and security fixes

- optionally, updating your intrusion rules and vulnerability database (VDB) and redeploying your configurations

- making any required configuration changes based on the information in New Features and Functionality

The next sections include detailed instructions not only on performing the update, but also on completing any post-update steps. Make sure you complete all of the listed tasks.

Updating Firepower Management Centers

Use the procedure in this section to update your Firepower Management Centers, including virtual Firepower Management Centers. For the Version 6.0.1.1 update, Firepower Management Centers reboot.

Caution: Before you update the Firepower Management Center, redeploy your configurations to any managed devices. Otherwise, the managed device update may fail.
reboot or shut down your appliances during the update until after you see the login prompt. The system may appear inactive during the pre-checks portion of the update; this is expected behavior and does not require you to reboot or shut down your appliances. Note: Updating a Firepower Management Center to Version 6.0.1.1 removes existing uninstallers from the appliance.
To update a Firepower Management Center:

Step 1 Read these release notes and complete any required pre-update tasks.

Step 2 Download the update from the Support site:

- for Firepower Management Centers and Firepower Management Centers Virtual:

Sourcefire_3D_Defense_Center_S3_Patch-6.0.1.1-1023.sh

Step 3 Upload the update to the Firepower Management Center by selecting System > Updates, then clicking Upload Update on the Product Updates tab. Browse to the update and click Upload.

The update is uploaded to the Firepower Management Center. The web interface shows the type of update you uploaded, its version number, and the date and time it was generated.

Step 4 Make sure that the appliances in your deployment are successfully communicating and that there are no issues reported by the health monitor.

Step 5 Click the System Status icon, then click the Tasks tab and make sure that there are no tasks in progress.

You must wait until any long-running tasks are complete before you begin the update. After the system update completes, to reduce clutter, remove the messages for these tasks from the Message Center.

Step 6 Select System > Updates.

The Product Updates tab appears.

Step 7 Click the install icon next to the update you uploaded.

The Install Update page appears.

Step 8 Select the Firepower Management Center and click Install. Confirm that you want to install the update and reboot the Firepower Management Center.

The update process begins. To view the task status, click the System Status icon, then click on the Tasks tab. However, after the Firepower Management Center completes its necessary pre-update checks, you are logged out. When you log back in, the Upgrade Status page appears. The Upgrade Status page displays a progress bar and provides details about the script currently running.

If the update fails for any reason, the page displays an error message indicating the time and date of the failure, which script was running when the update failed, and instructions on how to contact Support. Do not restart the update.
restart the update. Instead, contact Support.
When the update completes, the Firepower Management Center displays a success message and reboots.

The update process begins. You can monitor the update's progress in the task queue (System > Monitoring > Task Status).
restart the update. Instead, contact Support.
Step 9 After the update finishes, clear your browser cache and force a reload of the browser. Otherwise, the user interface may exhibit unexpected behavior.

Step 10 Log into the Firepower Management Center.

Step 11 Review and accept the End User License Agreement (EULA). Note that you are logged out of the appliance if you do not accept the EULA.

Step 12 Select Help > About and confirm that the software version is listed correctly: Version 6.0.1.1. Also note the versions of the intrusion rule update and VDB on the Firepower Management Center; you will need this information later.

Step 13 Verify that the appliances in your deployment are successfully communicating and that there are no issues reported by the health monitor.

Step 14 If the rule update available on the Support site is newer than the rules on your Firepower Management Center, import the newer rules. Do not auto-apply the imported rules at this time.

For information on rule updates, see the Firepower Management Center Configuration Guide.

Step 15 If the VDB available on the Support site is newer than the VDB on your Firepower Management Center, install the latest VDB.

Installing a VDB update causes a short pause in traffic flow and processing, and may also cause a few packets to pass uninspected. For more information, see the Firepower Management Center Configuration Guide.

Step 16 Redeploy your configurations to all managed devices.

Deployment may cause a short pause in traffic flow and processing, and may also cause a few packets to pass uninspected. For more information, see the Firepower Management Center Configuration Guide.

Step 17 If a patch for Version 6.0.1.1 is available on the Support site, apply the latest patch as described in the Firepower System Release Notes for that version.
.
You must update to the latest patch to take advantage of the latest enhancements and security fixes.

Caution: Although the configuration options for Firepower Management Center high availability appear in the Integration page of the user interface, high availability is not supported for Firepower Management Centers in Version 6.0.1. Do not attempt to place Firepower Management Centers into high availability.

Updating Managed Devices and Cisco ASA with FirePOWER Servicess

After you update your Firepower Management Centers to Version 6.0.1.1, use them to update the devices they manage.

You must use a Firepower Management Center running Version 6.0 to update any managed device that does not have its own web interface. For Cisco ASA with FirePOWER Services running on the ASA 5506-X, ASA 5506H-X, ASA 5506W-X, ASA 5508-X, or ASA 5516-X, you can update the module using the Firepower Management Center or connect to the ASA device and update the ASA Firepower module using local management via ASDM. For more information see the Cisco ASA with FirePOWER Services Local Management Release Notes.

Updating managed devices is a two-step process. First, download the update from the Support site and upload it to the managing Firepower Management Center. Next, install the software. You can update multiple devices at once, but only if they use the same update file.

When you update clustered Cisco ASA with FirePOWER Services, apply the update one device at a time, allowing the update to complete before updating the second device.

For the Version 6.0.1.1 update, all devices reboot. 7000 Series and 8000 Series devices do not perform traffic inspection, switching, routing, NAT, VPN, or related functions during the update and devices running Firepower Threat Defense do not perform VPN functions. Depending on how your devices are configured and deployed, the update process may also affect traffic flow and link state. For more information, see Traffic Flow and Inspection During the Update.

Firepower Threat Defense is new for the Version 6.0 Firepower System. You can reimage your Cisco ASA with FirePOWER Services to use Firepower Threat Defense, or you can reimage Cisco ASA devices with Firepower Threat Defense to a supported ASA version. For information about installing a Version 6.0.1.1 Firepower Threat Defense image on supported ASA models, see the Cisco Firepower Threat Defense Quick Start Guide.

Caution: Before you update a managed device, use its managing Firepower Management Center to redeploy your configuration to the managed device. Otherwise, the managed device update may fail.

Caution: Installing an update and deploying configurations can interrupt traffic inspection due to Snort restarts and system restarts. How these interruptions affect traffic depends on how the managed device handles traffic. For more information, see Traffic Flow and Inspection During the Update. reboot or shut down your appliances during the update until after you see the login prompt. The system may appear inactive during the pre-checks portion of the update; this is expected behavior and does not require you to reboot or shut down your appliances.

Uninstalling the Update

The following sections help you uninstall the Version 6.0.1.1 update from your appliances:

- Planning the Uninstallation

- Uninstalling the Update from a Managed Device

- Uninstalling the Update from a Virtual Managed Device

- Uninstalling the Update from a Firepower Threat Defense device

- Uninstalling the Update from a Cisco ASA with FirePOWER Services

- Uninstalling the Update from a Firepower Management Center

- Uninstalling the Update from a Cisco ASA with FirePOWER Services Managed by ASDM

Planning the Uninstallation

Before you uninstall the update, you must thoroughly read and understand the following sections.

Uninstallation Method

You must uninstall updates locally. You cannot use a Firepower Management Center to uninstall the update from a managed device.

For all physical appliances and virtual Firepower Management Centers, uninstall the update using the local web interface. Because virtual managed devices do not have a web interface, you must use the bash shell to uninstall the update.

Order of Uninstallation

Uninstall the update in the reverse order that you installed it. That is, first uninstall the update from managed devices, then from Firepower Management Centers.

Uninstalling the Update from Clustered or Paired Appliances

Clustered devices and Firepower Management Centers in high availability pairs must run the same version of the Firepower System. Although the uninstallation process triggers an automatic failover, appliances in mismatched pairs or clusters do not share configuration information, nor do they install or uninstall updates as part of their synchronization. If you need to uninstall an update from redundant appliances, plan to perform the uninstallations in immediate succession.

To ensure continuity of operations, uninstall the update from clustered devices and paired Firepower Management Centers one at a time. First, uninstall the update from the secondary appliance. Wait until the uninstallation process completes, then immediately uninstall the update from the primary appliance.

restart the uninstall or change configurations on its peer. Instead, contact Support.

Uninstalling the Update from Stacked Devices

All devices in a stack must run the same version of the Firepower System. Uninstalling the update from any of the stacked devices causes the devices in that stack to enter a limited, mixed-version state.

To minimize impact on your deployment, Cisco recommends that you uninstall an update from stacked devices simultaneously. The stack resumes normal operation when the uninstallation completes on all devices in the stack.

Uninstalling the Update from Devices Deployed Inline

Managed devices do not perform traffic inspection, switching, routing, or related functions while the update is being uninstalled. Depending on how your devices are configured and deployed, the uninstallation process may also affect traffic flow and link state. For more information, see Traffic Flow and Inspection During the Update.

Uninstalling the Update and Online Help

Uninstalling the Version 6.0.1.1 update does not revert the online help to its previous version. If the version of your online help does not match that of your Firepower System software, your online help may contain documentation for unavailable features and may have problems with context sensitivity and link functionality.

After the Uninstallation

After you uninstall the update, there are several steps you should take to ensure that your deployment is performing properly. These include verifying that the uninstall succeeded and that all appliances in your deployment are communicating successfully.

The next sections include detailed instructions not only on performing the update, but also on completing any post-update steps. Make sure you complete all of the listed tasks.

Known Issues

You can view known issues reported in this release using the Cisco Bug Search Tool (https://tools.cisco.com/bugsearch/). A Cisco account is required.

The following known issues are reported in Version 6.0.1.1:

- In rare cases, the system experiences issues after deploying a network discovery policy with user discovery enabled such as no event processing and network discovery, and generates a The data correlator process exited (x) times error message. If the system suddenly stops processing events and generates a The data correlator process exited (x) times error message, contact Support. (CSCuz15233, CSCuy60302)

- In some cases, if you deploy an SSL policy to a device managed by an Firepower Management Center running Version 6.0.0 and update the Firepower Management Center to Version 6.0.1.1, then redpeloy configuration and the system experiences a high volume of traffic, the system experiences a disruption in traffic. As a workaround, restart the system. (CSCuz19469)

- ASA FirePOWER devices managed by ASDM do not support the Windows 10 OS. (CSCuz42216)

- In some cases, if you create a cluster of 8250 devices running Version 6.0.1.1, the Firepower Management Center incorrectly displays a You have unapplied changes message even though there are no changes to deploy. (CSCuz48049)

- If you move a physical interface from admin context to a non-admin context on an ASA Firepower device configured with multiple security contexts managed by an Firepower Management Center via CLI command, the Firepower Management Center does not update the interface list in the Interfaces tab of the Device Management page ( Devices > Devices Management ) when it should. (CSCuz58989)

- In some cases, if you create multiple domains or realms with users and restart the system, the user session may not time out when it should. (CSCuz68841)

- In some cases, if you update a system from Version 6.0.0.1 to Version 6.0.1.1, initial deployment may fails. As a workaround, redeploy configuration. (CSCuz70743)

- If you create a TCP or UDP port objects in the Individual Objects page ( Object Management > Ports > Individual Objects ) and edit an access control rule, then view the Ports tab of the edit window, you cannot add the new TCP or UDP port objects to the access control rule. (CSCuz76431)

- If you enable both Log at Beginning of Connection and Log at End of Connection options in the Logging tab of an access control rule applied to an ASA Firepower device managed by ASDM, the system incorrectly disables the selected server configured for SNMP and Syslog alerting even though the checkbox for the SNMP and Syslog server remain checked. (CSCuz80854)

- If you uninstall Version 6.0.1.1 on a registered device running Firepower Threat Defense, the device experiences a disruption in traffic. As a workaround, deploy configuration after you uninstall Version 6.0.1.1 from the device running Firepower Threat Defense. (CSCva10906)

- If you place an access control rule configured to Allow a subdomain URL (site.example.com) above an access control rule configured to Block the domain URL (example.com), the system may block request to subdomain URL. As a workaround, create an access control to Allow each subdomain URL (site.example.com, site2.example.com, etc.) you do not want blocked instead of the rule to block the domain URL, then save and redeploy. (CSCvc59811)

The following known issues were reported in previous releases:

- The system allows you to select a custom context on the ASA FirePOWER Configuration page ( Configuration > ASA FirePOWER Configuration ) of an ASA Firepower module managed by ASDM running Version 6.0.1 even though custom context is not supported on devices managed by ASDM. Cisco strongly recommends using admin context on the ASA FirePOWER Configuration page. (CSCus71713, CSCuy18360)

- You may experience latency if you use Firefox version 38.0.1 to view your Firepower Management Center's interface. As a workaround, use Firefox 41 or later or use a different web browser. (CSCuv11830)

- In some cases, if you create an access control policy when registering a device on a subdomain, the system creates the access control policy in the global domain instead of the subdomain when it should not. (CSCut56951)

- In some cases, if you edit a route map from Allow to Block on a Firepower Threat Defense device, the system does not deploy the edit to your managed devices. As a workaround, create a new route map on the Route Map page ( Objects > Object Management > Route Map ) with the correct action and redeploy. (CSCuu27697)

- In some cases, if you edit the default network access policy in the advanced tab of the Access Control page ( Policies > Access Control ), the system incorrectly displays the default network access policy as an intrusion policy on the deployment dialog window. (CSCuv48221)

- Online help does not open if you click the help icon on the Select Comparison page ( ASA FirePOWER Configuration > Policies > Files > Compare Policies ) of an ASA Firepower module managed via ASDM. (CSCuw21863)

- In some cases, if you view All Events (Not Dropped) in the Intrusion Events table view page of a Firepower 7000 Series or 8000 Series device and sort the table by a maximum of six fields including Review By and Count and then generate a report, report generation fails. As a workaround, exclude either the Review By and Count field values or, if you include both the Review By and Count fields, only nor more than three additional field values when generating a report from the intrusion events page. (CSCuw29993)

- You cannot name a device group with a name that includes the plus ( + ) character even though the system generates a This field contains invalid characters. Only alphanumerics, hyphen ( - ), underscore ( _ ), period ( . ), and plus ( + ) are allowed message. (CSCuw44373)

- In some cases, if you edit the browser and shell timeout threshold values on the Shell Timeout page ( System > Configuration > Shell Timeout ) and redeploy, the system logs out of inactive Firepower Management Centers up to one minute after the configured threshold values. (CSCuw48568)

- In some cases, editing a file list in a domain causes any file policy in that domain to be marked out-of-date. (CSCuw52764)

- The Device Management page ( Devices > Device Management ) does not display device override values in the tooltip for device objects. (CSCuw53371)

- External certificates from Version 5.4.x are not supported in Version 6.0: the only curves supported in Version 6.0 are prime192v1 , prime256v1 , secp384r1 and secp521r1 . You must update your system to Version 6.0 to obtain supported external certificates. (CSCuw54749)

- In some cases, if you create an access control policy referencing both a file policy containing a file rule configured to Detect Files and an SSL policy configured to Decrypt--Resign or Decrypt--known key on a system sending and receiving emails with Outlook 2013, the Connection Events page ( Analysis > Connections > Events ) does not include email file attachments in generated events. (CSCuw65152)

- In some cases, if you refresh the tabs in the Device Management page ( Devices > Device Management ) or the NAT page ( Devices > NAT ) or the VPN page ( Devices > VPN ), the system does not clear the cache on the page being refreshed and the Save button is un-operational. As a workaround, cancel any edits made to the page or tab and select the device you want to edit again. (CSCuw75367)

- In some cases, if you create an SSL policy containing a certificate with more than one status, such as expired or revoked, the Certificate Status column of the Connection Events page ( Analysis > Connections > Events ) does not display a status. (CSCuw76040)

- In rare cases, if you create or edit a device interface on the Device Management page ( Devices > Devices Management ), the system generates a No cache exists to discard and resume error and you cannot deploy. As a workaround, refresh the Device Management page and redeploy. (CSCuw77505)

- In some cases, if you incorrectly configure OSPFv3, RIP or Border Gateway Protocol on a device's virtual router page ( Devices > Devices Management > Virtual Router ) and leave the configuration page without saving changes, the system generates a To revert back the configuration pop-up; click Yes to clean the virtual router configuration page of any edits or click No causes the system to generate the To revert back the configuration pop-up multiple times before saving the virtual router configuration page without any edits. (CSCuw78916)

- If you deploy a network discovery policy to a Firepower 9300 cluster or clustered or stacked Firepower 7000 Series or 8000 Series devices (in Version 6.0 known as a high availability pair), the system incorrectly counts all devices in the cluster or stack rather than indicating one device for the cluster or stack. (CSCuw79241, CSCuw79243)

- If you want to reimage your ASA 5506-X, ASA 5506H-X, ASA 5506W-X, ASA 5508-X, or ASA 5516-X device to Firepower Threat Defense, you must verify your ROMMON image meets the recommended version, Version 1.1.8, prior to reimaging. For more information on reimaging to Firepower threat Defense, see the Cisco Firepower Threat Defense Quick Start Guide . (CSCuw79771)

- After initial setup on a Firepower Management Center, Firepower 7000 Series, or 8000 Series device, if you are connecting to the appliance from behind a network address translator (NAT) device, the system provides a redirect URL containing the IP address for the IP address you configured for the appliance rather than the NAT IP you are connecting to, and the session times out. As a workaround, correct the URL to use the NAT IP used to connect via web. (CSCuw79967)

- If you uninstall Version 5.4.1.3 or later to an earlier 5.4.x version and then update the system to Version 6.0, the update to Version 6.0 fails. Update your system to the latest version prior to updating your system to Version 6.0. (CSCuw81780)

- In some cases, if you do not select the required licenses for a device prior to device registration, the system generates an Initial policy deployment not started due to validation errors. For details, redeploy manually message. For more information on the correct licenses to select for your device, see the Licensing the FireSIGHT System chapter of the Firepower Management Center Configuration Guide . (CSCuw85743)

- If you edit a Firepower Threat Defense interface to use a static route IPV6 address for either a network or gateway IP address that has already been configured, the system allows you to do so even though the configuration is invalid. (CSCuw87053)

- When configuring OSPFv3 routing settings on a Firepower Threat Defense device, if you configure redistribution using a route map that is not used elsewhere in the device configuration, then delete the redistribution, deployment fails. As a workaround, either remove a route map first & deploy or configure use of the same route map elsewhere before deleting the OSPFv3 redistribution configuration. (CSCut87162)

- In some cases, if you deploy a NAT policy containing rules targeted to Firepower 7000 Series or 8000 Series managed devices' routed interfaces and then cluster the managed devices (known is Version 6.0 as a high-availability pair), some NAT rules continue to target a managed device's routed interface instead of changing to target a high availability interface when it should. As a workaround, edit the rule containing the individual interface, manually create a high availability interface, then redeploy. (CSCuw89223)

- The HTTP Listing page ( Device > Platform Settings > Firepower Threat Defense Platform Settings > HTTP ) lists Authentication Certificate as a configurable field when it is not. (CSCuw89605)

- In some cases, the system generates events for large amounts of HTTP traffic processed by a port that is not specified in the HTTP preprocessor rule. As a workaround, add the port to the HTTP preprocessor rule with GID 119 and SID 15 . (CSCuw90033)

- If you initiate deployment while backing up the Firepower Management Center, a message does not appear to indicate that the communication channel is blocked and the policy cannot deploy. Wait until backup process is complete and then deploy. (CSCuw90629)

- In some cases, if you create an access control policy that has an intrusion policy as the default action, the variable set icon next to the default action does not display properly. As a workaround, change the default action to use a different intrusion policy, which makes the icon show up, and then change your default action back to the previous intrusion policy. (CSCuw94067)

- In some cases, the Firepower Management Center's Deploy window displays an incorrect timestamp after you update the Firepower Management Center to Version 6.0 and deploy configuration changes. (CSCuw94083)

- In some cases, if you create an OSPFv3 router but do not configure a manual router-id in the Advanced Settings tab of the router page ( Devices > Device Management > Router ), the system does not use unnamed IPv4 IP addresses and generates an OPSFv3 router process will not start as no router ID has been configured. Neither router ID in OSPFv3 nor IPv4 address configured in Interfaces error message. (CSCuw95485)

- If you create a correlation rule configured to match a MAC Vendor is condition, the system generates a Warning: no vendors match this string warning and does not execute the correlation rule. As a workaround, update your vulnerability database (VDB). If the VDB update does not resolve the issue, use the MAC Vendor contains condition instead of the MAC Vendor is condition. (CSCuw96022)

- The link to the Cisco Smart Software Manager from the Firepower Management Center Smart Licensing user interface page ( System > Local > System Policy ) directs to an updated link, which also redirects. As a workaround, if the redirect does not occur quickly enough, connect to https://software.cisco.com/#module/SmartLicensing . (CSCuw96552)

- In some cases, deploy fails on a device running Version 5.4.0 that is registered to a Firepower Management Center running Version 6.0 if you deploy an access control policy that references a file policy configured for malware protection. (CSCuw97809)

- In some cases, if you enable sensitive data detection in the Advanced Settings on the Intrusion Policy page ( Policies > Intrusion > Intrusion Policy ), then switch to another domain before saving, the system does not reload the Intrusion Policy page in the destination domain when it should. As a workaround, save or manually reload the Intrusion Policy page. (CSCuw97864)

- In some cases, if the time configured on a device running Version 6.0 is set ahead of the time configured on a Firepower Management Center, registering the managed device to the Firepower Management Center causes connectivity issues and the system may not be able to restore connectivity. As a workaround, execute the /etc/rc.d/init.d/pm restart CLI command. If you continue to experience connectivity issues, contact Support. (CSCuw97948)

- The system shutdown CLI command causes ASA Firepower modules (ASA 5506-X, ASA 5506H-X, ASA 5506W-X, ASA 5508-X, ASA 5516-X) running Firepower Threat Defense to restart instead of shut down. (CSCuw98231)

- In some cases, if your user interface initiates a restore, the session will be disconnected and you must log in again to see the status of restore operation. (CSCuw98296)

- Version 6.0 does not support the Safari web browser on systems running the MAC OS. Use Firefox, Chrome, or Internet Explorer. (CSCuw98876)

- In some cases, if the system hosting a virtual device experiences a high amount of traffic, deploying to the virtual device may cause temporary network issues. (CSCux00380)

- In some cases, intrusion events do not display the correct source IP address or the correct destination IP address. As a workaround, view the Connection Events page ( Analysis > Connections > Events ) to view the correct source and destination IP addresses of an intrusion event. (CSCux00385)

- In some cases pinholes are not created for Real-time Transport Protocol (RTP) connections established by calls using the Session Initiation Protocol (SIP), which prevents the VOIP channel creation for the SIP call. (CSCux03758, CSCux09765)

- Although an application detector is available for the Skinny (SCCP) protocol, pinholes are not created for RTP connections established by SCCP packets. (CSCux05468)

- The system may experience dropped packets if you edit the access control policy to an intrusion preventative default action and deploy to registered devices configured with routed, transparent, or inline interfaces. (CSCux02726)

- If you enable the CPU Usage health monitor on the Health Policy page ( Health > Health Policy ) for a Firepower Threat Defense device, the device generates transient erroneous 100% CPU load alarms during deployment. (CSCux07384)

- In some cases, if you create a Firepower Threat Defense device in transparent mode and register the device to a Firepower Management Center, then assign an IP address to an interface being used as the device's diagnostic interface, the Firepower Management Center does not successfully deploy the assigned IP address to the Firepower Threat Defense device. Cisco recommends restarting the Firepower Threat Defense device for the changes to take effect. (CSCux07416)

- In some cases, if you only edit the logical device's management interface of a Firepower 9300 device and deploy, the system does not warn you that the device must reboot to deploy changes when it should. (CSCux07831)

- In some cases, when deploying policies to a large number of devices, policy deployment times out and fails when Snort fails to restart. (CSCux07861)

- Rarely, during booting of the Firepower 9300, it may fail to initialize and become operational. When this happens the device will automatically reboot. No interaction is required, the device will become operational after the successful boot attempt. (CSCux07881)

- In some cases, if you deploy a clustered Firepower Threat Defense device and attempt to move the device from one subdomain to another subdomain, moving the device fails and the system generates an Updating Domain management changes failed error message. (CSCux08012)

- In some cases on Firepower 9300, if one of the nodes fails a health check during a deployment, the node is separated from the configured cluster and deployment to the cluster fails. Such a situation is recoverable on its own and when the node re-joins the cluster, retry deployment. (CSCux08115)

- In the Firepower 9300 Chassis Manager, you may not be able to edit the interface in the last row on the Interfaces screen. In addition, you may not be able to manually select some interfaces during logical device provisioning from the Chassis Manager. As a workaround, decrease the font size of your web browser. (CSCux08577)

- In some cases, if you create a cluster of Firepower 9300 devices on a Firepower Management Centerand configure interface IP addresses and a translated address pool through the Firepower Management Center user interface, the IP Pool configuration does not deploy to the device if you deploy immediately after configuring. As a workaround, edit the Interface and IP Pool again and redeploy. (CSCux09023)

- If you deploy a NAT policy which resides in a subdomain to a Firepower 7000 Series or 8000 Series device and move the device to new domain, deploy fails. As a workaround, create a new NAT policy in a new domain and target the correct device, then redeploy. (CSCux10651)

- In some cases, if you create a VPN deployment on a registered device and move the device from one domain to another domain, then deploy, deploy fails and the system generates a Pre-deploy Global Configuration Generation. Cannot find policy information error message. As a workaround, remove the VPN configuration prior to moving the device to another domain. An alternative workaround is to unregister and then register the device to the Firepower Management Center, then create a VPN deployment and deploy. (CSCux10820, CSCux10820)

- In some cases, if a 7000 Series or 8000 Series high availability pair and the Firepower Management Center experiences a disruption in communication, you cannot break the high availability pair. If you cannot break a high availability pair, contact Support. (CSCux18768)

- Use of a certificate with an RSASSA-PSS signature algorithm on a Firepower Management Centerr is not supported in Version 6.0. If you update a Firepower Management Center using such a certificate to Version 6.0 or add such a certificate in Version 6.0, the system does not allow you to log into the Management Center web interface and generates an Unable to authorize access. If you continue to have difficulty accessing this device, please contact the system administrator error. As a workaround, prior to update, generate and install an SSL certificate with either a sha1WithRSAEncryption or sha256WithRSAEncryption algorithm and restart the Firepower Management Center, or use the default Firepower Management Center certificate and restart the appliance. If you are unable to access the user interface on your Firepower Management Center, contact Support. (CSCux30610)

- In some cases, if you enable a field in a network analysis (NAP) policy that is blank by default and enter a custom value, deploying the NAP policy fails. (CSCux32261)

- If the certificate used by your Firepower Management Center was generated using a public server key larger than 2048 bits, you will not be able to log into the Firepower Management Center web interface after updating to Version 6.0. As a workaround, replace certificates that were created with larger public keys by generating a server certificate request and then applying a certificate generated using that request to the Firepower Management Center. You can do the server certificate request and the certificate upload through the local configuration settings on the Firepower Management Center ( System > Local > Configuration > HTTPS Certificate ). If you generate a certificate without using a CSR from the Firepower Management Center, use a public key of 2048 bits or less. If you generate a certificate that contains more than 2048 bits and lose access to the Management Center web interface, contact Support. (CSCux35430)

- Version 6.0.1 does not support 2-byte characters in correlation policy names. If you use 2-byte characters in the name of a correlation policy and deploy, the system does not correctly apply the correlation rule. (CSCux35635)

- You are able to use non-numerical characters as IP addressed in the IPv4 or IPv6 Prefix List when you should not. If you use non-numerical characters for the Prefix List and include the Prefix List, deploy fails. (CSCux40496, CSCux40499)

- If you manage a Firepower Threat Defense Virtual (VMware or Amazon Web Services (AWS), or a Firepower Threat Defense Virtual in a high availability pair, the License page ( System > License ) displays an incorrect number of licenses applied to virtual devices. (CSCux42926, CSCux78687)

- If you add SNMP access to an ASA Firepower managed by ASDM on the System Policy page ( Configuration > ASA FirePOWER configuration > Local > System Policy ) and select Version 3 from the SNMP Version drop-down list, then Add User and expand the Authentication Protocol drop-down list, the system does not generate any options. (CSCuy46264)

- If you right click in the Networks tab of the Network Discovery page ( Policies > Network Discovery ), the system incorrectly generates the context menu even if a rule is not selected. (CSCuy46940)

- In some cases, if you configure transparent inline mode or passive mode on a registered device and deploy an intrusion rule, the system does not generate VLAN tags for all traffic types in the expanded packet view of the Intrusion Events page ( Analysis > Intrusion > Events ). (CSCuy47287)

- In some cases, if the system experiences a failover, the rate of transferring HTTP traffic may slow down. (CSCuy47595)

- If you view the web interface via the Chrome web browser, the system may not allow you to Add Security Zon e or edit an existing security zone of a registered NGIPSv device from the Security Zone tab of the Object Management page ( Object > Object Management > Security Zone ). As a workaround, reload the current page or use a different web browser. (CSCuy48328)

- If you import an internal certificate on the Object Management page ( Object > Object Management ) and cancel the Import Internal Certificate Authority window before saving the certificate, then attempt to import the same internal certificate, the system generates the Import Internal Certificate Authority window but does not display any information in the window and you cannot import the certificate. (CSCuy49034)

- In some cases, if deploy an intrusion rule containing an AppID web application condition and the system detects an HTTP session followed by an FTP session, the system incorrectly categorizes the FTP session as an HTTP session and experiences issues. (CSCuy49662)

- In some cases, the system does not display intrusion rules deployed at the Global domain in the expanded packet view of the Intrusion Events page ( Analysis > Intrusion > Events ). (CSCuy49667)

- If you create a cluster of the following ASA FirePOWER Services devices, the system does not dispaly the correct cluster icon on both the Deploy dialog window or the Device page: The ASA 5585-X-SSP-10, ASA 5585-X-SSP-20, ASA 5585-X-SSP-40, or the ASA 5585-X-SSP-60. (CSCuy51025)

- In some cases, if you create a syslog alert and the system experiences issues, the system generates extraneous health alerts about enabled detection engines. As a workaround, disable the syslog alert and deploy configurations. (CSCuy51339)

- In some cases, if you break a 7000 Series or 8000 Series high availability pair, the system keeps the high availability configuration in the deployments tab of the System Alerts screen when it should not. (CSCuy51614)

- If you check the Enable Auto Update s option in the Import Rules page ( Objects > intrusion Rules > Import Rules ), the system incorrectly defaults to an invalid value. If you check Enable Auto Updates , you must manually set the auto update minutes value. (CSCuy51949)

- In rare cases, if you reconfigure multiple domains or traffic profiles and delete a domain while changes are saving, the system experiences issues. As a workaround, wait until configurations are saved and deployed before deleting a domain. (CSCuy54834)

- In some cases, leaving a Firepower Management Center Virtual connected the Cisco cloud may cause system issues. (CSCuy56120)

- In some cases, the system stops added new hosts to the network map and the host view of the Discovery Event page ( Analysis > Hosts > Discovery Events ) incorrectly displays the host limit has been reached. (CSCuy57044)

- In some cases, if you break a Firepower Threat Defense high availability pair, one of the devices in the pair stays in standalone mode and the system cannot recreate the high availability pair. (CSCuy57756)

- If you view the web interface in Japanese, the Save button on the VMware Tool page (System > VMware Tool) is not translated when it should. (CSCuy58426)

- If you view the web interface in Japanese and click Deploy from the Policies page and view the deploy window, the Cancel button in the deploy window is not translated when it should. (CSCuy58661)

- In some cases, updating the Firepower Management Centerr to Version 6.0.1 via the Chrome web browser causes policy pages to load slowly. As a workaround, use either the Firefox or Internet Explorer web browsers. (CSCuy58664)

- In some cases, if registered ASA devices with Firepower Threat Defense or ASA Firepower modules experience bursts of high volume of traffic, device interfaces processing incoming traffic drops packets and the CPU does not appear to experience high usage. (CSCuy59642, CSCuy66405)

- If you deploy a NAP policy with Max Detect selected as the base policy, the system only deploys the policy to registered ASA devices with Firepower Threat Defense. As a workaround, if you must deploy a NAP policy with Max Detect selected as the base policy, click the Add A Layer option and disable the following options prior to deploying: Decompress SWF file (LZMA) , Decompress SWF File (Deflate) , and Decompress PDF File (Deflate) . (CSCuy60390)

- The Identify as Special Identities/Guest if authentication cannot identify user checkbox in identity rule configuration is incorrectly named. It should be named Identify as Guest if authentication cannot identify user . (CSCuy65461)

- If you click Add Task on the Scheduling page ( Configuration > ASA FirePOWER Configuration > Tools > Scheduling ) of an ASA device managed by ASDM and view the values displayed in the time drop-down list, the web interface incorrectly colors the values red and the values are not fully visible. (CSCuy69547)

- The Firepower Management Center cannot successfully deploy configuration to a Firepower Threat Defense high availability pair using an EtherChannel connection as the LAN failover link, and attempting to break the high availability pair may fail.(CSCuy73041)

- If you edit a device registered in a leaf domain from the Global domain while using Internet Explorer version 11, the system does not redirect you to the device edit page when it should. As a workaround, edit the device in the domain it is assigned to. (CSCuy73776)

- In some cases, if you create an access control rule and add a base policy in the Inheritance Settings window in the Security Intelligence tab of Initial Access Control Policy page ( Policies > Access Control > Access Control ), then check the Inherit from base policy option, the system does not let you uncheck the Inherit from base policy option. As a workaround, remove the inherited base policy from the access control rule and save, then add the base policy in the Inheritance Settings window again. (CSCuy74319)

- If you update a Cisco ASA with FirePOWER Services to Version 6.0.1 and attempt to deploy policies via ASDM, policy deployment may fail. As a workaround, download and apply the latest SRU from the Support site or add the device to a Firepower Management Center and deploy the policy from the Firepower Management Center. (CSCuy84095)
