What’s New in This Release
– Cisco 5520 Wireless Controller
– Cisco 8540 Wireless Controller
- The Cisco Aironet 1040 Series, 1140 Series, and 1260 Series access points have feature parity with Cisco Wireless Release 8.0. Features introduced in Cisco Wireless Release 8.1 and later are not supported on these access points.
- We recommend that you install Cisco Wireless Controller Field Upgrade Software, Release 1.10.0.0 for the following platforms:
– Cisco Flex 7500 Series Wireless Controllers
– Cisco 8500 Series Wireless Controllers
– Cisco Virtual Wireless Controller
For more information, see Release Notes for Cisco Wireless Controller Field Upgrade Software, Release 1.10.0.0.
– Dynamic Bandwidth Selection (DBS)—Automatic and intelligent configuration of 5-GHz channel bandwidth (20, 40, 80 MHz) for good channel width. This can be achieved by the learning of both client mix and the presence of neighboring APs and wireless networks.
– Flexible Dynamic Frequency Selection (DFS)—Automatic adjustment of channel selection and channel width for 5 GHz spectral regions requiring radar detection and avoidance.
– Enhanced Interference Mitigation—Event-driven RRM (ED-RRM) is additionally triggered by Wi-Fi interference (faster channel change than the typical dynamic channel assignment cycle in RRM).
– Optimized Roaming Extensions—802.11v Basic Service Set (BSS) Transition Management (the infrastructure provides explicit advice to clients for reassociation and roaming).
- Cisco WLAN Express and Best Practices on Wireless Controllers —The following enhancements are made to the Cisco WLAN Express feature in this release:
– Simplified initial (day 0) setup for Cisco WLCs is now extended to all Cisco WLCs and also comes with over-the-air setup. The best practices defaults now also enable RF parameter optimization and network profiles.
– Improved user-interface is modern, responsive, flexible, and mobile friendly.
– New dashboard enables easy monitoring of AP and Client performance parameters. Search capability along with AP and Client detail pages allows for easy wireless troubleshooting.
– Best Practices monitoring page reports status of Best Practices and provides a one-click Fix It option to enable them (or roll back).
For more information about the new dashboard and Best Practices, see the Online Help.
- Application Visibility and Control (AVC) for FlexConnect local switched access points —This release extends the AVC functionality from Cisco WLC to the AP. The AVC on FlexConnect AP provides application visibility and control for locally switched client traffic. The AVC on FlexConnect uses Protocol Pack 8.0 and NBAR engine version 16.
- Monitoring the High Availability (HA) standby WLC —The HA-MIB that enables the administrator to monitor the status and health of the active and standby WLC is enhanced. Standby WLC information is available via CLI, WLC GUI, and SNMP. Management platforms can use the SNMP information to monitor the HA pair instance using a single interface.
- Cisco WLC integration with Lync SDN API —This feature enables a Cisco WLC to integrate with a Microsoft Lync Server. Using Microsoft Lync SDN API, the Lync Server sends a notification when a Lync event, such as a voice call, video call, file transfer, or Desktop sharing, occurs on the network. The Cisco WLC interprets the API message, to take the appropriate QoS actions, and provides more visibility (mean opinion score [MOS] or Lync Client Heath) into the Lync events on the wireless network using the Lync SDN dashboard.
Note This feature is supported only with 1.2 or other 1.2 version compatible Microsoft Lync Server SDN API.
The Cisco WLC integration with Lync SDN API feature is not supported on Cisco 2504 Wireless Controller.
– Per-Client AAA override for AVC profiles
– AVC per application, per client-based rate limiting on WLAN
– Integration of AVC profiles with local policy classification on WLC
– AVC directional QoS DSCP marking for upstream and downstream traffic
- Seamless roaming with Inter-Release Controller Mobility (IRCM) between Cisco 8510 WLC, Cisco 8540 WLC, and Cisco 5520 WLC with Cisco 5760 WLC—Enables seamless mobility and wireless services across high scale WLCs running Cisco AireOS and Cisco IOS using new mobility for features such as Layer 2 and Layer 3 roaming and guest access or termination.
- With Release 8.1 in a New Mobility environment, Cisco WLCs running Cisco Wireless software cannot function as mobility controllers (MC). However, the Cisco WLCs can function as guest anchors.
- AAA override of VLAN for FlexConnect —Allows a VLAN name to map to different VLAN IDs depending on the local site or FlexConnect group.
- Kernel-based virtual machine (KVM) support is added for Virtual Wireless Controller
- Guest Anchor Priority —Assigns a fixed priority to each anchor WLC or HA pair. The highest priority Cisco WLC is designated as the primary anchor. This feature also allows load distribution in round-robin fashion if the priorities are of the same assigned value.
- Multi-country domain support on WLC—Enables multiple country codes to be configured on a single Cisco WLC with bridge mode APs connected.
- Improved Mesh convergence time—Builds upon improvements made in Release 8.0 by adding channel change notification messaging, further improving network availability times.
- RRM on 5GHz RAP—RRM algorithms can run on the 5-GHz backhaul radio for root access points (RAPs) that do not have a child mesh access point (MAP) associated with them. This allows the RAP to find the optimal 5-GHz channel to operate on. When a MAP associates with this RAP, the RRM functionality is automatically disabled to ensure stable backhaul performance.
- Ethernet over GRE (EoGRE) tunneling from Cisco WLC and AP —Enables tunneling of data traffic from Cisco WLC or AP to a mobile packet core using EoGRE tunnels.
Note The EoGRE feature is not supported on Cisco 700 Series Access Points.
- TrustSec support on Cisco 5520 WLC, Cisco Flex 7510 WLC, and Cisco 8500 Series WLC—Security Group Tag Exchange Protocol (SXP) support on Cisco 5520, Flex 7510, 8510, and 8540 WLCs can be used to advertise Security Group TAG (SGT) information to SGT-capable switches so that appropriate role-based access control lists (RBACLs) can be activated depending on the role information represented by the SGT.
- FlexConnect Client Debugging on AP —FlexConnect client-based debugging allows client specific debugging to be enabled for an AP or groups of APs, and allows the syslog server configuration to log those debug messages.
- Other enhancements:
– With Release 8.1.102.0, in Cisco vWLC, by default, the WLAN is locally switched.
– License management for Cisco vWLC is changed from requiring a license file to Right to Use Licensing model. Users are required to accept an End User License Agreement (EULA) to the entitled quantity.
For more information about using the Right to Use Licensing feature, see the Configuring Right to Use Licensing section in the Cisco Wireless Controller Configuration Guide.
– Log Source IP on failed attempts to log into WLC (CSCul84825)
– Add metadata to backup config file (CSCuq51498)
– Rogue AP validation against AAA (CSCuj15410)
– Framed MTU size (CSCuh33897)
– Added support for RFC3576 Global DNS config (CSCug92480)
– DNS RADIUS feature changes (CSCug92480)
– Create configurable DOT1x exclusion attempts (CSCuo87508)
– WLC—RADIUS multiple UDP source port support for RADIUS protocol (CSCus51456)
Enabling multiple source ports allows the number of outstanding RADIUS requests to be increased. With single source port, the number of outstanding requests was limited to 255 for each authentication and accounting request. Added the following command to address this:
config radius ext-source-ports { enable | disable }
Note Cisco 5508 WLC and WiSM2 support 8 RADIUS queues; Cisco 5520, Flex 7500 Series, and 8500 Series WLCs support 16 RADIUS queues.

Upgrading to Cisco WLC Software Release 8.1.102.0
Guidelines and Limitations
- When using Mobility Anchor WLANs, after you upgrade from a release that is prior to Release 8.1, guest client may not be exported because after the Cisco WLC boots with the new 8.1 image, the anchor list does not get updated with the correct priority in the new 8.1 feature for anchor priority list. The workaround is to update the anchor list with the correct priority in the priority list.
Note Release 8.1.111.0 and later have a fix for this issue and you do not have to apply this workaround. For more information, see CSCuu97761.
- If you are using Cisco Virtual Wireless Controller and upgrade from Release 8.0.x to Release 8.1.x, the AP counts from the license are not retained. The workaround is to remove the license file and manually add the AP count using the Right to Use Licensing feature.
For more information about using the Right to Use Licensing feature, see the Configuring Right to Use Licensing section in the Cisco Wireless Controller Configuration Guide.
- Cisco WLC Release 7.3.112.0, which is configured for new mobility, might revert to old mobility after upgrading to Release 7.6, even though Release 7.6 supports new mobility. This issue occurs when new mobility, which is compatible with the Cisco 5760 Wireless LAN Controller and the Cisco Catalyst 3850 Series Switch, are in use. However, old mobility is not affected.
a. Enter the following commands:
b. After the reboot, press Esc on the console, and use the boot menu to select Release 7.6.
c. After booting on Release 7.6, set back the primary boot, and save the configuration by entering the following command:
Note The epings are not available in the Cisco 5500 Series WLC when New Mobility is enabled.
Note If you downgrade from a Cisco WLC release that supports new mobility to a Cisco WLC release that does not support new mobility, for example, Cisco Wireless Release 7.6 to Release 7.3.x and you download the 7.6 configuration file with new mobility in enabled state, the release that does not support new mobility will have the new mobility feature in enabled state.
- If you downgrade from Release 8.1.102.0 to a 7.x release, the trap configuration is lost and must be reconfigured.
- If you have ACL configurations in a Cisco WLC, and downgrade from a 7.4 or later release to a 7.3 or earlier release, you might experience XML errors on rebooting the Cisco WLC. However, these errors do not have any impact on any of the functionalities or configurations.
- If you are upgrading from Release 8.0.140.0 or 8.0.15x.0 to a later release and also have the multiple country code feature configured, the feature configuration is corrupted after the upgrade. For more information, see CSCve41740.
- If you are upgrading from a 7.4.x or earlier release to a release later than 7.4, the Called Station ID type information is mapped to the RADIUS Accounting Called Station ID type; which, by default, is set to apradio-mac-ssid. You can configure the RADIUS Authentication Called Station ID type information by using the config radius auth callStationIdType command.
- When FlexConnect APs (known as H-REAP APs in the 7.0.x releases) that are associated with a Cisco WLC that has all the 7.0.x software releases prior to Release 7.0.240.0, upgrade to Release 8.1.102.0, the APs lose the enabled VLAN support configuration. The VLAN mappings revert to the default values of the VLAN of the associated interface. The workaround is to upgrade from Release 7.0.240.0 and later 7.0.x releases to Release 8.1.102.0.
Note In case of FlexConnect VLAN mapping deployment, we recommend that the deployment be done using FlexConnect groups. This allows you to recover VLAN mapping after an AP rejoins the Cisco WLC without having to manually reassign the VLAN mappings.
- When a client sends an HTTP request, the Cisco WLC intercepts it for redirection to the login page. If the HTTP GET request that is intercepted by the Cisco WLC is longer than 2000 bytes, the Cisco WLC drops the packet. Track CSCuy81133 for a possible enhancement to address this restriction.
- We recommend that you install Release 1.9.0.0 of Cisco Wireless LAN Controller Field Upgrade Software (FUS), which is a special AES package that contains several system-related component upgrades. These include the bootloader, field recovery image, and FPGA/MCU firmware. Installing the FUS image requires special attention because it installs some critical firmware. The FUS image is independent of the runtime image. For more information, see http://www.cisco.com/c/en/us/td/docs/wireless/controller/release/notes/fus_rn_OL-31390-01.html.
Note The FUS image installation process reboots the Cisco WLC several times and reboots the runtime image. The entire process takes approximately 30 minutes. We recommend that you install the FUS image in a planned outage window.
Note If you are using a Cisco 2500 Series controller and you intend to use the Application Visibility and Control (AVC) and NetFlow protocol features, you must install Release 1.9.0.0 of Cisco Wireless LAN Controller FUS. This is not required if you are using other controller hardware models.
- After you upgrade to Release 7.4, networks that were not affected by the existing preauthentication access control lists might not work because the rules are now enforced. That is, networks with clients configured with static DNS servers might not work unless the static server is defined in the preauthentication ACL.
- On the Cisco Flex 7500 Series WLCs, if FIPS is enabled, the reduced boot options are displayed only after a bootloader upgrade.
Note Bootloader upgrade is not required if FIPS is disabled.
- If you have to downgrade from one release to another, you might lose the configuration from your current release. The workaround is to reload the previous Cisco WLC configuration files saved on the backup server, or to reconfigure the Cisco WLC.
- It is not possible to directly upgrade to Release 8.1.102.0 release from a release that is earlier than Release 7.0.98.0.
- You can upgrade or downgrade the Cisco WLC software only between certain releases. In some instances, you must first install an intermediate release prior to upgrading to Release 8.1.102.0. Table 5 shows the upgrade path that you must follow before downloading Release 8.1.102.0.
If you upgrade directly to Release 7.6.x or a later release from a release that is earlier than Release 7.5 directly to Release 7.6.X or a later release, the predownload process on Cisco Aironet 2600 and 3600 APs fails. After the Cisco WLC is upgraded to Release 7.6.x or a later release, the new image is loaded on Cisco AP2600 and Cisco AP3600. After the upgrade to a Release 7.6.X image, the predownload functionality works as expected. The predownload failure is only a one-time failure.
- When you upgrade the Cisco WLC to an intermediate software release, you must wait until all of the access points that are associated with the Cisco WLC are upgraded to the intermediate release before you install the latest Cisco WLC software. In large networks, it can take some time to download the software on each access point.
- You can upgrade to a new release of the Cisco WLC software or downgrade to an earlier release even if Federal Information Processing Standard (FIPS) is enabled.
- We recommend that you insert Interoperability test for RADIUS to show Cisco ISE.
- When you upgrade to the latest software release, the software on the access points associated with the Cisco WLC is also automatically upgraded. When an access point is loading software, each of its LEDs blinks in succession.
- We recommend that you access the Cisco WLC GUI using Microsoft Internet Explorer 9 or a later version or Mozilla Firefox 17 or a later version.
Note Microsoft Internet Explorer 8 might fail to connect over HTTPS because of compatibility issues. In such cases, you can explicitly enable SSLv3 by entering the config network secureweb sslv3 enable command.
- Cisco WLCs support standard SNMP MIB files. MIBs can be downloaded from the Software Center on Cisco.com.
- The Cisco WLC software is factory installed on your Cisco WLC and is automatically downloaded to the access points after a release upgrade and whenever an access point joins a Cisco WLC. We recommend that you install the latest software version available for maximum operational benefit.
- Ensure that you have a TFTP, FTP, or SFTP server available for the software upgrade. Follow these guidelines when setting up a server:
– Ensure that your TFTP server supports files that are larger than the size of Cisco WLC software Release 8.1.102.0. Some TFTP servers that support files of this size are tftpd32 and the TFTP server within the Prime Infrastructure. If you attempt to download the 8.1.102.0 Cisco WLC software and your TFTP server does not support files of this size, the following error message appears:
– If you are upgrading through the distribution system network port, the TFTP or FTP server can be on the same subnet or a different subnet because the distribution system port is routable.
- When you plug a Cisco WLC into an AC power source, the bootup script and power-on self test is run to initialize the system. During this time, press Esc to display the bootloader Boot Options menu. The menu options for the Cisco 5500 Series WLC differ from the menu options for the other Cisco WLC platforms.
Bootloader menu for Cisco 5500 Series WLC:
Bootloader menu for other Cisco WLC platforms:
Enter 1 to run the current software, enter 2 to run the previous software, enter 4 (on Cisco 5500 Series WLC), or enter 5 (on Cisco WLC platforms other than 5500 series) to run the current software and set the Cisco WLC configuration to factory defaults. Do not choose the other options unless directed to do so.
Note See the Installation Guide or the Quick Start Guide pertaining to your Cisco WLC platform for more details on running the bootup script and power-on self test.
- The Cisco WLC bootloader stores a copy of the active primary image and the backup image. If the primary image becomes corrupted, you can use the bootloader to boot with the backup image.
With the backup image stored before rebooting, choose Option 2: Run Backup Image from the boot menu to boot from the backup image. Then, upgrade with a known working image and reboot the Cisco WLC.
- You can control the addresses that are sent in the Control and Provisioning of Wireless Access Points (CAPWAP) discovery responses when NAT is enabled on the Management Interface using the following command:
config network ap-discovery nat-ip-only { enable | disable }
– enable —Enables use of NAT IP only in a discovery response. This is the default. Use this command if all the APs are outside the NAT gateway.
– disable —Enables use of both NAT IP and non-NAT IP in a discovery response. Use this command if APs are on the inside and outside the NAT gateway, for example, Local Mode and OfficeExtend APs are on the same Cisco WLC.
Note To avoid stranding of APs, you must disable AP link latency (if enabled) before you use the disable option for the config network ap-discovery nat-ip-only command. To disable AP link latency, use the config ap link-latency disable all command.
- You can configure 802.1p tagging by using the config qos dot1p-tag { bronze | silver | gold | platinum } command. For Release 7.2.103.0 and later releases, if you tag 802.1p packets, the tagging has an impact on only wired packets. Wireless packets are impacted only by the maximum priority level set for QoS.
- You can reduce the network downtime using the following options:
– You can predownload the AP image.
– For FlexConnect access points, use the FlexConnect AP upgrade feature to reduce traffic between the Cisco WLC and the AP (main site and the branch). For more information about the FlexConnect AP upgrade feature, see the Cisco Wireless Controller Configuration Guide.
Note Predownloading Release 8.1.102.0 on a Cisco Aironet 1240 access point is not supported when upgrading from a previous Cisco WLC release. If predownloading is attempted on a Cisco Aironet 1240 access point, an AP disconnect will occur momentarily.
- Do not power down the Cisco WLC or any access point during the upgrade process; otherwise, you might corrupt the software image. Upgrading a Cisco WLC with a large number of access points can take as long as 30 minutes, depending on the size of your network. However, with the increased number of concurrent access point upgrades supported, the upgrade time should be significantly reduced. The access points must remain powered, and the Cisco WLC must not be reset during this time.
- To downgrade from Release 8.1.102.0 to Release 6.0 or an earlier release, perform either of these tasks:
– Delete all the WLANs that are mapped to interface groups, and create new ones.
– Ensure that all the WLANs are mapped to interfaces rather than interface groups.
- After you perform the following functions on the Cisco WLC, reboot the Cisco WLC for the changes to take effect:
– Enable or disable link aggregation (LAG)
– Enable a feature that is dependent on certificates (such as HTTPS and web authentication)
– Add a new license or modify an existing license
– Increase the priority of a license
– Install the vendor-device certificate
– Upload the configuration file
– Install the Web Authentication certificate
– Make changes to the management interface or the virtual interface

Special Notes for Licensed Data Payload Encryption on
Cisco Wireless LAN Controllers
Datagram Transport Layer Security (DTLS) is required for all Cisco 600 Series OfficeExtend Access Point deployments to encrypt data plane traffic between the APs and the Cisco WLC. You can purchase Cisco Wireless LAN Controllers with either DTLS that is enabled (non-LDPE) or disabled (LDPE). If DTLS is disabled, you must install a DTLS license to enable DTLS encryption. The DTLS license is available for download on Cisco.com.
Important Note for Customers in Russia
If you plan to install a Cisco Wireless LAN Controller in Russia, you must get a Paper PAK, and not download the license from Cisco.com. The DTLS Paper PAK license is for customers who purchase a Cisco WLC with DTLS that is disabled due to import restrictions, but have authorization from local regulators to add DTLS support after the initial purchase. Refer to your local government regulations to ensure that DTLS encryption is permitted.
Note Paper PAKs and electronic licenses that are available are outlined in the respective Cisco WLC platform data sheets.

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
Warning Do not locate the antenna near overhead power lines or other electric light or power circuits, or where it can come into contact with such circuits. When installing the antenna, take extreme care not to come into contact with such circuits, as they may cause serious injury or death. For proper installation and grounding of the antenna, please refer to national and local codes (e.g. U.S.: NFPA 70, National Electrical Code, Article 810, Canada: Canadian Electrical Code, Section 54). Statement 280
Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all current-carrying conductors). Statement 13
Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground connector. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024
Warning Read the installation instructions before you connect the system to its power source. Statement 10
Warning Do not work on the system or connect or disconnect any cables (Ethernet, cable, or power) during periods of lightning activity. The possibility of serious physical injury exists if lightning should strike and travel through those cables. In addition, the equipment could be damaged by the higher levels of static electricity present in the atmosphere. Statement 276
Warning Do not operate the unit near unshielded blasting caps or in an explosive environment unless the device has been modified to be especially qualified for such use. Statement 364

Warning This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security. Statement 1017
Safety Information
Follow the guidelines in this section to ensure proper operation and safe use of the Cisco WLCs and access points.
FCC Safety Compliance Statement
FCC Compliance with its action in ET Docket 96-8, has adopted a safety standard for human exposure to RF electromagnetic energy emitted by FCC-certified equipment. When used with approved Cisco Aironet antennas, Cisco Aironet products meet the uncontrolled environmental limits found in OET-65 and ANSI C95.1, 1991. Proper operation of this radio device according to the instructions in this publication results in user exposure substantially below the FCC recommended limits.
Safety Precautions
For your safety, and to help you achieve a good installation, read and follow these safety precautions. They might save your life.
- If you are installing an antenna for the first time, for your own safety as well as others’, seek professional assistance. Your Cisco sales representative can explain which mounting method to use for the size and type of antenna you are about to install.
- Select your installation site with safety as well as performance in mind. Electric power lines and phone lines look alike. For your safety, assume that any overhead line can kill you.
- Call your electric power company. Tell them your plans and ask them to come look at your proposed installation. This is a small inconvenience considering your life is at stake.
- Plan your installation carefully and completely before you begin. Successfully raising a mast or tower is largely a matter of coordination. Each person should be assigned to a specific task and should know what to do and when to do it. One person should be in charge of the operation to issue instructions and watch for signs of trouble.
- When installing an antenna, remember:
– Do not work on a wet or windy day.
– Do dress properly—shoes with rubber soles and heels, rubber gloves, long-sleeved shirt or jacket.
- If the assembly starts to drop, get away from it and let it fall. Remember that the antenna, mast, cable, and metal guy wires are all excellent conductors of electrical current. Even the slightest touch of any of these parts to a power line completes an electrical path through the antenna and the installer: you!
- If any part of an antenna system should come in contact with a power line, do not touch it or try to remove it yourself. Call your local power company. They will remove it safely.
- If an accident should occur with the power lines, call for qualified emergency help immediately.
Installation Instructions
See the appropriate quick start guide or hardware installation guide for instructions on installing Cisco Wireless Controllers and APs.
Note To meet regulatory restrictions, all external antenna configurations must be installed by experts.
Personnel installing the Cisco WLCs and APs must understand wireless techniques and grounding methods. APs with internal antennas can be installed by an experienced IT professional.
The Cisco WLC must be installed by a network administrator or qualified IT professional, and the proper country code must be selected. After the installation, access to the Cisco WLC should be password protected by the installer to maintain compliance with regulatory requirements and ensure proper unit functionality.
