Important Notes

- Potential Traffic Outage (9.1(7.9) through 9.1(7.15))--Due to bug CSCvd78303 , the ASA may stop passing traffic after 213 days of uptime. The effect on each network will be different, but it could range from an issue of limited connectivity to something more extensive like an outage. You must upgrade to a new version without this bug, when available. In the meantime, you can reload the ASA to gain another 213 days of uptime. Other workarounds may be available. See Field Notice FN-64291 for affected versions and more information.

- Cisco ASA Clientless SSL VPN Portal Customization Integrity Vulnerability—Multiple vulnerabilities have been fixed for clientless SSL VPN in ASA software, so you should upgrade your software to a fixed version. See http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20141008-asa for details about the vulnerability and a list of fixed ASA versions. Also, if you ever ran an earlier ASA version that had a vulnerable configuration, then regardless of the version you are currently running, you should verify that the portal customization was not compromised. If an attacker compromised a customization object in the past, then the compromised object stays persistent after you upgrade the ASA to a fixed version. Upgrading the ASA prevents this vulnerability from being exploited further, but it will not modify any customization objects that were already compromised and are still present on the system.

- EtherChannel configuration on the 4GE SSM disallowed—Interfaces on the 4GE SSM, including the built-in module on the ASA 5550 (GigabitEthernet 1/ x ), are not supported as members of EtherChannels. However, although not supported, configuration was not disallowed until 9.0(1). If you configured any 4GE SSM interfaces as EtherChannel members, then upgrading to 9.0(1) or later will remove the channel-group membership configuration from those interfaces. You must alter your interface configuration to comply with supported interface types. (CSCtq62715)

- ASA 9.1(3) features for the ASA CX require ASA CX Version 9.2(1).

- Upgrading ASA Clustering from 9.0(1) or 9.1(1)—Due to many bug fixes, we recommend the 9.0(2) or 9.1(2) release or later for ASA clustering. If you are running 9.0(1) or 9.1(1), you should upgrade to 9.0(2) or 9.1(2) or later. Note that due to CSCue72961, hitless upgrading is not supported.

- Upgrading to 9.1(2.8) or 9.1(3) or later—See Upgrading the Software.

- ASA CX software module SSD—An SSD is required to install the ASA CX software module on the ASA 5500-X series. Non-Cisco SSDs are not supported.

Limitations and Restrictions

- Downgrading from 9.1(4) and later with failover and VPN using inner IPv6 with IKEv2—If you want to downgrade your failover pair, and you are using the 9.1(4) inner IPv6 VPN feature, then you must disconnect the connection before downgrading. If you downgrade without disconnecting, then any new AnyConnect connection that is assigned the same IP address as the previous connection will fail. (CSCul56646)

- Clientless SSL VPN with a self-signed certificate on the ASA—When the ASA uses a self-signed certificate or an untrusted certificate, Firefox 4 and later and Safari are unable to add security exceptions when browsing using an IPv6 address HTTPS URL (FQDN URL is OK): the “Confirm Security Exception” button is disabled. See https://bugzilla.mozilla.org/show_bug.cgi?id=633001 . This bug affects all SSL connections originating from Firefox or Safari to the ASA (including clientless SSL VPN connections, and ASDM connections). To avoid this bug, configure a proper certificate for the ASA that is issued by a trusted certificate authority. For Internet Explorer 9 and later, use compatibility mode.

- When configuring for IKEv2, for security reasons you should use groups 21, 20, 19, 24, 14, and 5. We do not recommend Diffie Hellman Group1 or Group2. For example, use

crypto ikev2 policy 10

group 21 20 19 24 14 5

- With a heavy load of users (around 150 or more) using a WebVPN plugin, you may experience large delays because of the processing overload. Using Citrix web interface reduces the ASA rewrite overhead. To track the progress of the enhancement request to allow WebVPN plug files to be cached on the ASA, refer to CSCud11756.

- (ASA 5510, ASA 5520, ASA 5540, and ASA 5550 only) We strongly recommend that you enable hardware processing using the crypto engine large-mod-accel command instead of software for large modulus operations such as 2048-bit certificates and DH5 keys. If you continue to use software processing for large keys, you could experience significant performance degradation due to slow session establishment for IPsec and SSL VPN connections. We recommend that you initially enable hardware processing during a low-use or maintenance period to minimize a temporary packet loss that can occur during the transition of processing from software to hardware.

commands are not applicable on these platforms.

Table 1 New Features for ASA Version 9.1(7.4)

Feature

Description

Remote Access Features

Clientless SSL VPN session cookie access restriction

You can now prevent a Clientless SSL VPN session cookie from being accessed by a third party through a client-side script such as Javascript.

Note: Use this feature only if Cisco TAC advises you to do so. Enabling this command presents a security risk because the following Clientless SSL VPN features will not work without any warning.

- Java plug-ins

- Java rewriter

- Port forwarding

- File browser

- Sharepoint features that require desktop applications (for example, MS Office applications)

- AnyConnect Web launch

- Citrix Receiver, XenDesktop, and Xenon

- Other non-browser-based and browser plugin-based applications

We introduced the following command: http-only-cookie.

This feature is also in 9.2(3) and 9.4(1).

Configurable SSH encryption and HMAC algorithm

Users can select cipher modes when doing SSH encryption management and can configure HMAC and encryption for varying key exchange algorithms.

Clientless SSL VPN cache disabled by default

The clientless SSL VPN cache is now disabled by default. Disabling the clientless SSL VPN cache provides better stability. If you want to enable the cache, you must manually enable it.

webvpn

cache

no disable

We modified the following command: cache

Also available in 9.5(2).

HTTP redirect support for IPv6

When you enable HTTP redirect to HTTPS for ASDM access or clientless SSL VPN, you can now redirect traffic sent an to IPv6 address.

We added functionality to the following command: http redirect

Administrative Features

show tech support enhancements

The show tech support command now:

- Includes dir all-filesystems output—This output can be helpful in the following cases:

— SSL VPN configuration: check if the required resources are on the ASA

— Crash: check for the date timestamp and presence of a crash file

- Includes show resource usage count all 1 output—Includes information about xlates, conns, inspects, syslogs, and so on. This information is helpful for diagnosing performance issues.

- Removes the show kernel cgroup-controller detail output—This command output will remain in the output of show tech-support detail .

Support for the cempMemPoolTable in the CISCO-ENHANCED-MEMPOOL-MIB

The cempMemPoolTable of the CISCO-ENHANCED-MEMPOOL-MIB is now supported. This is a table of memory pool monitoring entries for all physical entities on a managed system.

Note: The CISCO-ENHANCED-MEMPOOL-MIB uses 64-bit counters and supports reporting of memory on platforms with more than 4GB of RAM.

New Features in Version 9.1(6)

Released: March 2, 2015

The following table lists the new features for ASA Version 9.1(6).

Table 2 New Features for ASA Version 9.1(6)

Feature

Description

Interface Features

Maximum MTU is now 9198 bytes

The maximum MTU that the ASA can use is 9198 bytes (check for your model’s exact limit at the CLI help). This value does not include the Layer 2 header. Formerly, the ASA let you specify the maximum MTU as 65535 bytes, which was inaccurate and could cause problems. If your MTU was set to a value higher than 9198, then the MTU is automatically lowered when you upgrade. In some cases, this MTU change can cause an MTU mismatch; be sure to set any connecting equipment to use the new MTU value.

We modified the following command: mtu

New Features in Version 9.1(5)

Released: March 31, 2014

Table 3 New Features for ASA Version 9.1(5)

Feature

Description

Administrative Features

Secure Copy client

The ASA now supports the Secure Copy (SCP) client to transfer files to and from a SCP server.

We introduced the following commands: ssh pubkey-chain, server (ssh pubkey-chain), key-string, key-hash, ssh stricthostkeycheck.

Improved one-time password authentication

Administrators who have sufficient authorization privileges may enter privileged EXEC mode by entering their authentication credentials once. The auto-enable option was added to the aaa authorization exec command.

Firewall Features

Transactional Commit Model on rule engine for access groups

When enabled, a rule update is applied after the rule compilation is completed; without affecting the rule matching performance.

Monitoring Features

SNMP hosts, host groups, and user lists

You can now add up to 4000 hosts. The number of supported active polling destinations is 128. You can specify a network object to indicate the individual hosts that you want to add as a host group. You can associate more than one user with one host.

Monitoring Features

NAT-MIB cnatAddrBindNumberOfEntries and cnatAddrBindSessionCount OIDs to allow polling for Xlate count.

Support was added for the NAT-MIB cnatAddrBindNumberOfEntries and cnatAddrBindSessionCount OIDs to support xlate_count and max_xlate_count for SNMP.

Also available in 8.4(5).

Remote Access Features

AnyConnect DTLS Single session Performance Improvement

UDP traffic, such as streaming media, was being affected by a high number of dropped packets when sent over an AnyConnect DTLS connection. For example, this could result in streaming video playing poorly or cease streaming completely. The reason for this was the relatively small size of the flow control queue.

We increased the DTLS flow-control queue size and offset this by reducing the admin crypto queue size. For TLS sessions, the priority of the crypto command was increased to high to compensated for this change. For both DTLS and TLS sessions, the session will now persist even if packets are dropped. This will prevent media streams from closing and ensure that the number of dropped packets is comparable with other connection methods.

Webtype ACL enhancements

We introduced URL normalization. URL normalization is an additional security feature that includes path normalization, case normalization and scheme normalization. URLs specified in an ACE and portal address bar are normalized before comparison; for making decisions on webvpn traffic filtering.

For example, if you have an https://calo.cisco.com/checkout/Devices/ bookmark, an https://calo.cisco.com/checkout/Devices/* under web type acl seems to match. However, since URL normalization has been introduced, both bookmark URL and web type ACL are normalized before comparison. In this example, https://calo.cisco.com/checkout/Devices is normalized to https://calo.cisco.com/checkout/Devices, and https://calo.cisco.com/checkout.Devices/* stays the same, so the two do not match.

You must configure the following to meet the requirement:

- To permit the bookmark URL (https://calo.cisco.com/checkout/Devices), configure the ACL to permit that URL

- To permit the URLs within the Devices folder, configure the ACL to permit https://calo.cisco.com/checkout/Devices/*

New Features in Version 9.1(4)

Released: December 9, 2013

Table 4 New Features for ASA Version 9.1(4)

Feature

Description

Remote Access Features

HTML5 WebSocket proxying

HTML5 WebSockets provide persistent connections between clients and servers. During the establishment of the clientless SSL VPN connection, the handshake appears to the server as an HTTP Upgrade request. The ASA will now proxy this request to the backend and provide a relay after the handshake is complete. Gateway mode is not currently supported.

We did not modify any commands.

IPv6 traffic can now be tunneled through IPsec/IKEv2 tunnels. This makes the ASA to AnyConnect VPN connections fully IPv6 compliant. GRE is used when both IPv4 and IPv6 traffic are being tunneled, and when both the client and headend support GRE. For a single traffic type, or when GRE is not supported by the client or the headend, we use straight IPsec.

Note This feature requires AnyConnect Client Version 3.1.05 or later.
Output of the show ipsec sa and show vpn-sessiondb detail anyconnect commands has been updated to reflect the assigned IPv6 address, and to indicate the GRE Transport Mode security association when doing IKEv2 dual traffic.

The vpn-filter command must now be used for both IPv4 and IPv6 ACLs. If the depracated ipv6-vpn-filter command is used to configure IPv6 ACLs the connection will be terminated.

Support for mobile devices connecting to Citrix server through the ASA now includes selection of a tunnel-group, and RSA Securid for authorization. Allowing mobile users to select different tunnel-groups allows the administrator to use different authentication methods.

We introduced the application-type command to configure the default tunnel group for VDI connections when a Citrix Receiver user does not choose a tunnel-group. A none action was added to the vdi command to disable VDI configuration for a particular group policy or user.

Split-tunneling of VPN traffic has been enhanced to support both exclude and include ACLs. Exclude ACLs were previously ignored.

Note This feature requires AnyConnect Client Version 3.1.03103 or later.

High Availability and Scalability Features

ASA 5500-X support for clustering

The ASA 5512-X, ASA 5515-X, ASA 5525-X, ASA 5545-X, and ASA 5555-X now support 2-unit clusters. Clustering for 2 units is enabled by default in the base license; for the ASA 5512-X, you need the Security Plus license.

Improved VSS and vPC support for health check monitoring

If you configure the cluster control link as an EtherChannel (recommended), and it is connected to a VSS or vPC pair, you can now increase stability with health check monitoring. For some switches, such as the Nexus 5000, when one unit in the VSS/vPC is shutting down or booting up, EtherChannel member interfaces connected to that switch may appear to be Up to the ASA, but they are not passing traffic on the switch side. The ASA can be erroneously removed from the cluster if you set the ASA holdtime timeout to a low value (such as .8 seconds), and the ASA sends keepalive messages on one of these EtherChannel interfaces. When you enable the VSS/vPC health check feature, the ASA floods the keepalive messages on all EtherChannel interfaces in the cluster control link to ensure that at least one of the switches can receive them.

Support for cluster members at different geographical locations (inter-site); Individual Interface mode only

You can now place cluster members at different geographical locations when using individual interface mode. See the configuration guide for inter-site guidelines.

Support for clustering with the Cisco Nexus 5000 and Cisco Catalyst 3750-X

The ASA supports clustering when connected to the Cisco Nexus 5000 and Cisco Catalyst 3750-X.

Basic Operation Features

DHCP rebind function

During the DHCP rebind phase, the client now attempts to rebind to other DHCP servers in the tunnel group list. Prior to this release, the client did not rebind to an alternate server, when the DHCP lease fails to renew.

Troubleshooting Features

Crashinfo dumps include AK47 framework information

Application Kernel Layer 4 to 7 (AK47) framework-related information is now available in crashinfo dumps. A new option, ak47, has been added to the debug menu command to help in debugging AK47 framework issues. The framework-related information in the crashinfo dump includes the following:

- Creating an AK47 instance.

- Destroying an AK47 instance.

- Generating an crashinfo with a memory manager frame.

- Generating a crashinfo after fiber stack overflow.

- Generating a crashinfo after a local variable overflow.

- Generating a crashinfo after an exception has occurred.

New Features in Version 9.1(3)

Released: September 18, 2013

Table 5 New Features for ASA Version 9.1(3)

Feature

Description

Module Features

Support for the ASA CX module in multiple context mode

You can now configure ASA CX service policies per context on the ASA.

Note Although you can configure per context ASA service policies, the ASA CX module itself (configured in PRSM) is a single context mode device; the context-specific traffic coming from the ASA is checked against the common ASA CX policy.
Requires ASA CX 9.2(1) or later.

We did not modify any commands.

ASA CX SSP-40 and -60 modules can be used with the matching level ASA 5585-X with SSP-40 and -60.

Requires ASA CX 9.2(1) or later.

Filtering packets captured on the ASA CX backplane

You can now filter packets that have been captured on the ASA CX backplane using the match or access-list keyword with the capture interface asa_dataplane command. Control traffic specific to the ASA CX module is not affected by the access-list or match filtering; the ASA captures all control traffic. In multiple context mode, configure the packet capture per context. Note that all control traffic in multiple context mode goes only to the system execution space. Because only control traffic cannot be filtered using an access list or match, these options are not available in the system execution space.

Requires ASA CX 9.2(1) or later.

We modified the following command: capture interface asa_dataplane.

You can now view the top bin sizes allocated and the top 10 PCs for each allocated bin size. Previously, you had to enter multiple commands to see this information (the show memory detail command and the show memory binsize command); the new command provides for quicker analysis of memory issues.

We introduced the following command: show memory top-usage.

Also available in 8.4(6).

Smart Call Home

We added a new type of Smart Call Home message to support ASA clustering.

A Smart Call Home clustering message is sent for only the following three events:

- When a unit joins the cluster

- When a unit leaves the cluster

- When a cluster unit becomes the cluster master

Each message that is sent includes the following information:

- The active cluster member count

- The output of the show cluster info command and the show cluster history command on the cluster master

We modified the following commands: show call-home, show running-config call-home.

Also available in 9.0(3).

Remote Access Features

user-storage value command password is now encrypted in show commands

The password in the user-storage value command is now encrypted when you enter show running-config.

We modified the following command: user-storage value.

Also available in 8.4(6).

New Features in Version 9.1(2)

Released: May 14, 2013

Table 6 lists the new features for ASA Version 9.1(2).

Note: Features added in 8.4(6) are not included in 9.1(2) unless they are explicitly listed in this table.

Table 6 New Features for ASA Version 9.1(2)

Feature

Description

Certification Features

FIPS and Common Criteria certifications

The FIPS 140-2 Non-Proprietary Security Policy was updated as part of the Level 2 FIPS 140-2 validation for the Cisco ASA series, which includes the Cisco ASA 5505, ASA 5510, ASA 5520, ASA 5540, ASA 5550, ASA 5580, ASA 5512-X, ASA 5515-X, ASA 5525-X, ASA 5545-X, ASA 5555-X, ASA 5585-X, and the ASA Services Module.

The Common Criteria Evaluation Assurance Level 4 (EAL4) was updated, which provides the basis for a specific Target of Evaluation (TOE) of the Cisco ASA and VPN platform solutions.

Encryption Features

Support for IPsec LAN-to-LAN tunnels to encrypt failover and state link communications

Instead of using the proprietary encryption for the failover key (the failover key command), you can now use an IPsec LAN-to-LAN tunnel for failover and state link encryption.

Note Failover LAN-to-LAN tunnels do not count against the IPsec (Other VPN) license.

Additional ephemeral Diffie-Hellman ciphers for SSL encryption

The ASA now supports the following ephemeral Diffie-Hellman (DHE) SSL cipher suites:

- DHE-AES128-SHA1

- DHE-AES256-SHA1

These cipher suites are specified in RFC 3268, Advanced Encryption Standard (AES) Ciphersuites for Transport Layer Security (TLS).

When supported by the client, DHE is the preferred cipher because it provides Perfect Forward Secrecy. See the following limitations:

- DHE is not supported on SSL 3.0 connections, so make sure to also enable TLS 1.0 for the SSL server.

!! set server version

ciscoasa(config)# ssl server-version tlsv1 sslv3

!! set client version

ciscoasa(config) # ssl client-version any

- Some popular applications do not support DHE, so include at least one other SSL encryption method to ensure that a cipher suite common to both the SSL client and server can be used.

- Some clients may not support DHE, including AnyConnect 2.5 and 3.0, Cisco Secure Desktop, and Internet Explorer 9.0.

We modified the following command: ssl encryption.

Also available in 8.4(4.1).

Management Features

Support for administrator password policy when using the local database

When you configure authentication for CLI or ASDM access using the local database, you can configure a password policy that requires a user to change their password after a specified amount of time and also requires password standards such as a minimum length and the minimum number of changed characters.

We introduced the following commands: change-password, password-policy lifetime, password-policy minimum changes, password-policy minimum-length, password-policy minimum-lowercase, password-policy minimum-uppercase, password-policy minimum-numeric, password-policy minimum-special, password-policy authenticate enable, clear configure password-policy, show running-config password-policy.

Also available in 8.4(4.1).

Support for SSH public key authentication

You can now enable public key authentication for SSH connections to the ASA on a per-user basis. You can specify a public key file (PKF) formatted key or a Base64 key. The PKF key can be up to 4096 bits. Use PKF format for keys that are too large to for the ASA support of the Base64 format (up to 2048 bits).

We introduced the following commands: ssh authentication.

Also available in 8.4(4.1); PKF key format support is only in 9.1(2).

AES-CTR encryption for SSH

The SSH server implementation in the ASA now supports AES-CTR mode encryption.

Improved SSH rekey interval

An SSH connection is rekeyed after 60 minutes of connection time or 1 GB of data traffic.

We introduced the following command: show ssh sessions detail.

Support for Diffie-Hellman Group 14 for the SSH Key Exchange

Support for Diffie-Hellman Group 14 for SSH Key Exchange was added. Formerly, only Group 1 was supported.

We introduced the following command: ssh key-exchange.

Also available in 8.4(4.1).

Support for a maximum number of management sessions

You can set the maximum number of simultaneous ASDM, SSH, and Telnet sessions.

We introduced the following commands: quota management-session, show running-config quota management-session, show quota management-session.

Also available in 8.4(4.1).

The default Telnet password was removed

To improve security for management access to the ASA, the default login password for Telnet was removed; you must manually set the password before you can log in using Telnet. Note: The login password is only used for Telnet if you do not configure Telnet user authentication (the aaa authentication telnet console command).

Formerly, when you cleared the password, the ASA restored the default of “cisco.” Now when you clear the password, the password is removed.

The login password is also used for Telnet sessions from the switch to the ASASM (see the session command). For initial ASASM access, you must use the service-module session command, until you set a login password.

We modified the following command: passwd.

Also available in 9.0(2).

Platform Features

Support for Power-On Self-Test (POST)

The ASA runs its power-on self-test at boot time even if it is not running in FIPS 140-2-compliant mode.

Additional tests have been added to the POST to address the changes in the AES-GCM/GMAC algorithms, ECDSA algorithms, PRNG, and Deterministic Random Bit Generator Validation System (DRBGVS).

Improved pseudo-random number generation (PRNG)

The X9.31 implementation has been upgraded to use AES-256 encryption instead of 3DES encryption to comply with the Network Device Protection Profile (NDPP) in single-core ASAs.

Support for image verification

Support for SHA-512 image integrity checking was added.

We modified the following command: verify.

Also available in 8.4(4.1).

Support for private VLANs on the ASA Services Module

You can use private VLANs with the ASASM. Assign the primary VLAN to the ASASM; the ASASM automatically handles secondary VLAN traffic. There is no configuration required on the ASASM for this feature; see the switch configuration guide for more information.

CPU profile enhancements

The cpu profile activate command now supports the following:

- Delayed start of the profiler until triggered (global or specific thread CPU%)

- Sampling of a single thread

We modified the following command: cpu profile activate [n-samples] [sample-process process-name] [trigger cpu-usage cpu% [process-name].

Also available in 8.4(6).

DHCP Features

DHCP relay servers per interface (IPv4 only)

You can now configure DHCP relay servers per-interface, so requests that enter a given interface are relayed only to servers specified for that interface. IPv6 is not supported for per-interface DHCP relay.

DHCP trusted interfaces

You can now configure interfaces as trusted interfaces to preserve DHCP Option 82. DHCP Option 82 is used by downstream switches and routers for DHCP snooping and IP Source Guard. Normally, if the ASA DHCP relay agent receives a DHCP packet with Option 82 already set, but the giaddr field (which specifies the DHCP relay agent address that is set by the relay agent before it forwards the packet to the server) is set to 0, then the ASA will drop that packet by default. You can now preserve Option 82 and forward the packet by identifying an interface as a trusted interface.

Module Features

ASA 5585-X support for network modules

The ASA 5585-X now supports additional interfaces on network modules in slot 1. You can install one or two of the following optional network modules:

- ASA 4-port 10G Network Module

- ASA 8-port 10G Network Module

- ASA 20-port 1G Network Module

Also available in 8.4(4.1).

ASA 5585-X DC power supply support

Support was added for the ASA 5585-X DC power supply.

Also available in 8.4(5).

Support for ASA CX monitor-only mode for demonstration purposes

For demonstration purposes only, you can enable monitor-only mode for the service policy, which forwards a copy of traffic to the ASA CX module, while the original traffic remains unaffected.

Another option for demonstration purposes is to configure a traffic-forwarding interface instead of a service policy in monitor-only mode. The traffic-forwarding interface sends all traffic directly to the ASA CX module, bypassing the ASA.

We modified or introduced the following commands: cxsc {fail-close | fail-open} monitor-only, traffic-forward cxsc monitor-only.

You can now use NAT 64 in conjunction with the ASA CX module.

We did not modify any commands.

In addition to adding the flow-update events, there are now NetFlow templates that allow you to track flows that experience a change to their IP version with NAT, as well as IPv6 flows that remain IPv6 after NAT.

Two new fields were added for IPv6 translation support.

Several NetFlow field IDs were changed to their IPFIX equivalents.

For more information, see the Cisco ASA Implementation Note for NetFlow Collectors.

Firewall Features

EtherType ACL support for IS-IS traffic (transparent firewall mode)

In transparent firewall mode, the ASA can now pass IS-IS traffic using an EtherType ACL.

We modified the following command: access-list ethertype {permit | deny} is-is.

Also available in 8.4(5).

Decreased the half-closed timeout minimum value to 30 seconds

The half-closed timeout minimum value for both the global timeout and connection timeout was lowered from 5 minutes to 30 seconds to provide better DoS protection.

Remote Access Features

IKE security and performance improvements

The number of IPsec-IKE security associations (SAs) can be limited for IKE v1 now, as well as IKE v2.

The IKE v2 Nonce size has been increased to 64 bytes.

There are no ASDM screen or CLI changes.

For IKE v2 on Site-to-Site, a new algorithm ensures that the encryption algorithm used by child IPsec SAs is not higher strength than the parent IKE. Higher strength algorithms will be downgraded to the IKE level.

This new algorithm is enabled by default. We recommend that you do not disable this feature.

For Site-to-Site, IPsec data-based rekeying can be disabled.

We modified the following command: crypto ipsec security-association.

Host Scan and the ASA use an improved process to transfer posture attributes from the client to the ASA. This gives the ASA more time to establish a VPN connection with the client and apply a dynamic access policy.

Also available in 8.4(5).

Clientless SSL VPN:

Windows 8 Support

This release adds support for Windows 8 x86 (32-bit) and Windows 8 x64 (64-bit) operating systems.

We support the following browsers on Windows 8:

- Internet Explorer 10 (desktop only)

- Firefox (all supported Windows 8 versions)

- Chrome (all supported Windows 8 versions)

See the following limitations:

- Internet Explorer 10:

— The Modern (AKA Metro) browser is not supported.

— If you enable Enhanced Protected Mode, we recommend that you add the ASA to the trusted zone.

— If you enable Enhanced Protected Mode, Smart Tunnel and Port Forwarder are not supported.

- A Java Remote Desktop Protocol (RDP) plugin connection to a Windows 8 PC is not supported.

Also available in 9.0(2).

Cisco Secure Desktop:

Windows 8 Support

CSD 3.6.6215 was updated to enable selection of Windows 8 in the Prelogin Policy operating system check.

See the following limitations:

- Secure Desktop (Vault) is not supported with Windows 8.

Also available in 9.0(2).

Monitoring Features

NSEL

Flow-update events have been introduced to provide periodic byte counters for flow traffic. You can change the time interval at which flow-update events are sent to the NetFlow collector. You can filter to which collectors flow-update records will be sent.

We introduced or modified the following commands: flow-export active refresh-interval, flow-export event-type.

Also available in 8.4(5).

New Features in Version 9.1(1)

Released: December 3, 2012

Table 7 lists the new features for ASA Version 9.1(1).

Note: Features added in 8.4(4.x), 8.4(5), 8.4(6), and 9.0(2) are not included in 9.1(1) unless they were listed in the 9.0(1) feature table.

Table 7 New Features for ASA Version 9.1(1)

Description

Module Features

Support for the ASA CX SSP for the ASA 5512-X through ASA 5555-X

We introduced support for the ASA CX SSP software module for the ASA 5512-X, ASA 5515-X, ASA 5525-X, ASA 5545-X, and ASA 5555-X. The ASA CX software module requires a Cisco solid state drive (SSD) on the ASA. For more information about the SSD, see the ASA 5500-X hardware guide.

We modified the following commands: session cxsc, show module cxsc, sw-module cxsc.

Note: There are no special requirements for Zero Downtime Upgrades for failover and ASA clustering with the following exceptions:

- Upgrading ASA clustering from 9.0(1) or 9.1(1): due to CSCue72961, hitless upgrading is not supported.

- Upgrade issues with 8.4(6), 9.0(2), and 9.1(2) for failover—Due to CSCug88962, you cannot perform a Zero Downtime Upgrade to 8.4(6), 9.0(2), or 9.1(3). You should instead upgrade to 8.4(5) or 9.0(3) or later. To upgrade 9.1(1), you cannot upgrade directly to the 9.1(3) release due to CSCuh25271, so there is no workaround for a Zero Downtime Upgrade; you must upgrade to 9.1(2) before you upgrade to 9.1(3) or later.
