Upgrading Cisco Wireless Release

This section describes the guidelines and limitations that you need to be aware of when you are upgrading the Cisco WLC software and the procedure to upgrade to this release.


Caution

Before you upgrade to this release, we recommend that you go through the following documents to understand various issues related to Cisco Wave 1 AP flash and the solution to address them:


Guidelines and Limitations

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

  • This release supports additional configuration options for 802.11r FT enable and disable. The additional configuration option is not valid for releases earlier than Release 8.4. If you downgrade from Release 8.7 to Release 8.2 or an earlier release, the additional configuration option is invalidated and defaulted to FT disable. When you reboot Cisco WLC with the downgraded image, invalid configurations are printed on the console. We recommend that you ignore this because there is no functional impact, and the configuration defaults to FT disable.

  • If you downgrade from Release 8.7 to a 7.x release, the trap configuration is lost and must be reconfigured.

  • 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 Cisco WLC to download a new image or to reboot Cisco WLC after the download of the new image. You can forcefully reboot Cisco WLC by entering the reset system forced command.

  • It is not possible to download some of the older configurations from Cisco WLC 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.

  • If you upgrade from Release 8.0.110.0 to a later release, the config redundancy mobilitymac mac-addr command's setting is removed. You must manually reconfigure the mobility MAC address after the upgrade.

  • 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 an 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 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 the Caveat ID CSCuy81133 for a possible enhancement to address this restriction.

  • When downgrading 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 that are saved in the backup server, or to reconfigure Cisco WLC.

  • When you upgrade Cisco WLC to an intermediate release, wait until all the APs that are associated with 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 AP.

  • You can upgrade to a new release of the Cisco WLC 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 Cisco WLC is also automatically upgraded. When an AP is loading software, each of its LEDs blinks in succession.

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

  • The Cisco WLC software is factory installed on your Cisco WLC and is automatically downloaded to the APs after a release upgrade and whenever an AP joins a Cisco WLC. 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 Cisco WLC 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 Cisco WLC 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 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, 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 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}

    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 Cisco WLC.


    Note

    To avoid stranding of APs, you must disable 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 Cisco WLC or any AP during the upgrade process. If you do this, the software image might get corrupted. Upgrading Cisco WLC 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 Cisco WLC must not be reset during this time.

  • To downgrade from this release 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 Cisco WLC, 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

  • From Release 8.3 or a later release, ensure that the configuration file that you back up does not contain the < or > special characters. If either of the special characters is present, the download of the backed up configuration file fails.

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 Version 3.0(4d) 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 CIMC 3.0(4d) images are available at the following locations
