What's Changed in Release 8.10.162.0

This section provides information about the changes and enhancements that are introduced in this release.

Access Points Swapping Wireless Controller Platform Fails Association

Cisco APs running Cisco 9800 Wireless 17.6.1 release image fails to associate with AireOS controller running 8.10.151.0 or earlier releases. The solution is to upgrade the controller to the 8.10.162.0 release before moving these APs to this controller network. For more information about this behavior, see the bug CSCvx98176 in the Resolved Caveats section.

Basic Service Set Coloring

In this release, the default setting is changed to disabled for this feature to prevent some clients from facing interoperability issues.

Upgrading a Cisco Wireless Release

This section describes the guidelines and limitations that you must be aware of when you are upgrading the Cisco Wireless release and the procedure to upgrade.

Guidelines and Limitations

  • An existing WLAN with ? in its name continues to be supported with this upgrade. However, you cannot include ? in the name when creating a new WLAN.

  • If an AP locks out the console due to default management user credentials, you must configure the controller AP global credential with non-default username and password to get access to the AP console.

  • WPA3 upgrade and downgrade guidelines:

    • If you want to upgrade from Release 8.5 to 8.10 and have WPA1 configured with none of the WPA1 AKM valid for Release 8.10, the WPA1 configuration is disabled after the upgrade.

    • If you downgrade from Release 8.10 to Release 8.5, if any AKM for SAE is configured, the AKM validation fails after the downgrade. The security is set to WPA2 and AKM to 802.1X. However, PMF configuration is retained, which results in an error.

    • FT set to enabled state and PMF set to Required state is allowed in Release 8.10 because PMF and FT configurations are decoupled. However, in Release 8.5, this configuration invalid. Therefore, upon downgrading to Release 8.5, the WLAN might be disabled.

  • Software downgrade guidelines for Release 8.10:

    • If you plan to downgrade the Cisco controller from Release 8.10 software, we recommend you to downgrade to Release 8.5.151.0 or later release to prevent the controller configuration files from being corrupted.

    • If you have configured new country codes in Release 8.10 and if you plan to downgrade to an earlier release, then we recommend that you remove the new country code configurations prior to the downgrade. For more information, see CSCvq91895.

  • Before downgrading or upgrading the Cisco Controller to another release check for APs or AP modes support. Ensure that only supported APs are connected and also the APs are moved to supported modes on the release that the controller is upgraded or downgraded to.

  • Legacy clients that require RC4 or 3DES encryption type are not supported in Local EAP authentication.

  • If you downgrade to Release 8.0.140.0 or 8.0.15x.0, and later upgrade to a later release and and also have the multiple country code feature configured, then the configuration file could get corrupted. When you try to upgrade to a later release, special characters are added in the country list causing issues when loading the configuation. For more information, see CSCve41740.


    Note

    Upgrade and downgrade between other releases does not result in this issue.
  • After downloading the new software to the Cisco APs, it is possible that a Cisco AP may get stuck in an upgrading image state. In such a scenario, it might be necessary to forcefully reboot the controller to download a new controller software image or to reboot the controller after the download of the new controller software image. You can forcefully reboot the controller by entering the reset system forced command.

  • It is not possible to download some of the older configurations from the controller because of the Multicast and IP address validations. See the "Restrictions on Configuring Multicast Mode" section in the Cisco Wireless Controller Configuration Guide for detailed information about platform support for global multicast and multicast mode.

  • When a client sends an HTTP request, the controller intercepts it for redirection to the login page. If the HTTP GET request that is intercepted by the controller is longer than 2000 bytes, the controller drops the packet. Track the Caveat ID CSCuy81133 for a possible enhancement to address this restriction.

  • When downgrading from one release to an earlier release, you might lose the configuration from your current release. The workaround is to reload the previous controller configuration files that are saved in the backup server, or to reconfigure the controller.

  • When you upgrade a controller to an intermediate release, wait until all the APs that are associated with the controller are upgraded to the intermediate release before you install the latest controller software. In large networks, it can take some time to download the software on each AP.

  • You can upgrade to a new release of the controller software or downgrade to an earlier release even if FIPS is enabled.

  • When you upgrade to the latest software release, the software on the APs associated with the controller is also automatically upgraded. When an AP is loading software, each of its LEDs blinks in succession.

  • Controllers support standard SNMP MIB files. MIBs can be downloaded from the software download page on Cisco.com.

  • The controller software that is factory-installed on your controller and is automatically downloaded to the APs after a release upgrade and whenever an AP joins a controller. We recommend that you install the latest software version available for maximum operational benefit.

  • Ensure that you have a TFTP, HTTP, 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 controller software image. Some TFTP servers that support files of this size are tftpd32 and the TFTP server within Cisco Prime Infrastructure. If you attempt to download the controller software image and your TFTP server does not support files of this size, the following error message appears:

      TFTP failure while storing in flash

    • 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.

  • The controller 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, from the Boot Options menu, choose Option 2: Run Backup Image to boot from the backup image. Then, upgrade with a known working image and reboot controller.

  • 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}

    The following are the details of the command:

    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 controller.


    Note

    To avoid stranding of APs, you must disable the AP link latency (if enabled) before you use the disable option in the config network ap-discovery nat-ip-only command. To disable AP link latency, use the config ap link-latency disable all command.
  • Do not power down the controller or any AP during the upgrade process. If you do this, the software image might get corrupted. Upgrading the controller with a large number of APs can take as long as 30 minutes, depending on the size of your network. However, with the increased number of concurrent AP upgrades supported, the upgrade time should be significantly reduced. The APs must remain powered, and controller must not be reset during this time.

  • After you perform the following functions on the controller, reboot it for the changes to take effect:

    • Enable or disable LAG.

    • Enable a feature that is dependent on certificates (such as HTTPS and web authentication).

    • Add a new license or modify an existing license.


      Note

      Reboot is not required if you are using Right-to-Use licenses.
    • Increase the priority of a license.

    • Enable HA.

    • Install the SSL certificate.

    • Configure the database size.

    • Install the vendor-device certificate.

    • Download the CA certificate.

    • Upload the configuration file.

    • Install the Web Authentication certificate.

    • Make changes to the management interface or the virtual interface.

CIMC Utility Upgrade for 5520 and 8540 Controllers

The AIR-CT5520-K9 and AIR-CT8540-K9 controller models are based on Cisco UCS server C series, C220 and C240 M4 respectively. These controller models have CIMC utility that can edit or monitor low-level physical parts such as power, memory, disks, fan, temperature, and provide remote console access to the controllers.

We recommend that you upgrade the CIMC utility to a version that has been certified to be used with these controllers. Controllers that have older versions of CIMC installed are susceptible to rebooting without being able to access FlexFlash, with the result that the manufacturing certificates are unavailable, and thus SSH and HTTPS connections will fail, and access points will be unable to join. See: CSCvo33873. The recommended versions addresses the vulnerability tracked in CSCvo01180 caveat.

The certified CIMC images are available at the following locations:
