Before you use a Cisco AP802 series lightweight access point with Cisco Wireless Release 8.4, you must upgrade the software in the Cisco 800 Series ISRs to Cisco IOS 15.1(4)M or later releases.

Note

For information about Cisco Wireless software releases that support specific Cisco access point modules, see the "Software Release Support for Specific Access Point Modules" section in https://www.cisco.com/c/en/us/td/docs/wireless/compatibility/matrix/compatibility-matrix.html.

What's New in Release 8.3.122.0

Release 8.3.122.0 is a repost of Release 8.3.121.0 with the inclusion of three caveats in the Resolved caveats list.

There are no other updates in this release, all resolved and open caveats in addition to three resolved bugs apply to this release.

Table 2. Resolved Caveats in Release 8.3.122.0

Caveat ID Number

Description

CSCvd27398

WLC management access stops working while WLAN services are still up

CSCve77722

WLAN in FlexConnect local switching drops NAC+802.1X and WPA2-PSK-WebAuth traffic on MAC filter fail

Backout changes - CSCvc78546 that leads to CSCve20123

What's New in Release 8.3.121.0

Multicast-to-Unicast Support for Passive Client ARPs

This feature enables the Cisco 5520 WLC to work along with Non-Cisco WGBs in Multicast-to-unicast mode to route ARP traffic from the wired clients behind the Non-Cisco WGBs to all the APs.

For more information, see the Multicast-to-Unicast Support for Passive Client ARPs section in the configuration guide.

AVC Based Selective Reanchoring

This feature is designed to reanchor clients when they roam from one Cisco WLC to another Cisco WLC. Reanchoring of Apple clients prevents depletion of IP addresses available for new clients in Cisco WLC.


Note

Some Apple clients roaming to another Cisco WLC fails to reassociate with the new Cisco WLC with the new IP address. These clients do not release the old IP address and therefore do not re-associate with the current Cisco WLC.


For more information, see the AVC Based Reanchoring section in the configuration guide.

Upgrade Warning for Deployments with TSPEC and CAC Enabled

If your network uses TSPEC (VoWLAN clients such as 792x, 882x, Spectralink) protocols, then do not upgrade to 8.3.121.0 if TSPEC and CAC are enabled. You can refer to the bug under open caveats—CSCve20123 for more information.

We recommend you to contact Cisco TAC for further support if you must upgrade to this release.

Important Upgrade Information for Cisco 2500 Series WLCs

If you are using a Cisco 2500 Series WLC and want to upgrade to Release 8.3.121.0, install the Cisco Wireless LAN Controller Field Upgrade Software, Release 1.9.0.0, or a later release. For more information, see http://www.cisco.com/c/en/us/support/wireless/2500-series-wireless-controllers/products-release-notes-list.html#anchor512.

Upgrading the Cisco WLC Software Release

Guidelines and Limitations

  • 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 https://www.cisco.com/c/en/us/td/docs/wireless/controller/release/notes/fus_rn_OL-31390-01.html.


    Note

    If you are using a Cisco 2500 Series controller, you must install Release 1.9.0.0 or higher of Cisco Wireless LAN Controller FUS. This is not required if you are using other controller hardware models.

    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.
  • Release 8.3 supports additional configuration options for 802.11r FT enable and disable. The additional configuration option is not valid for older releases. If you downgrade from Release 8.3.x 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 8.3.122.0 to a 7.x release, the trap configuration is lost and must be reconfigured.

  • If you downgrade from Release 8.3.122.0 to Release 8.1, the Cisco Aironet 1850 Series AP, whose mode prior to the downgrade was Sensor is shown to be in unknown mode after the downgrade. This is because the Sensor mode is not supported in Release 8.1.

  • If you have an IPv6-only network and are upgrading to Release 8.3.122.0 or a later release, ensure that the following is done:

    • Enable IPv4 and DHCPv4 on the network—Load a new Cisco WLC software image on all Cisco WLCs plus Supplementary AP Bundle images on the Cisco 2504 WLC, 5508 WLC, and WiSM2 or perform a predownload of AP images on the required Cisco WLCs.

    • Reboot Cisco WLC immediately or at the preset time.

    • Ensure that all Cisco APs are associated with Cisco WLC.

    • Disable IPv4 and DHCPv4 on the network.

  • After downloading new software to the Cisco APs, it is possible that a Cisco AP may get stuck in an “upgrading image” state. In such a case of a stranded Cisco AP, it may be necessary to forcefully reboot the Cisco WLC to download a new image or to reboot the Cisco WLC after the download of the new image. You can forcefully reboot the Cisco WLC by entering the reset system forced command.

  • It is not possible to download some of the older configurations from the Cisco WLC because of the Multicast and IP address validations. See the Restrictions on Configuring Multicast Mode section in the 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 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 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 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 8.3.122.0, 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 8.3.122.0.


    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.

  • 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 8.3.122.0 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 8.3.122.0. The following table shows the upgrade path that you must follow before downloading Release 8.3.122.0.


    Note

    If you upgrade directly to 7.6.x or a later release from a release that is earlier than 7.5, the predownload functionality on Cisco Aironet 2600 and 3600 APs fails. The predownload functionality failure is only a one-time failure. After the upgrade to 7.6.x or a later release, the new image is loaded on the said Cisco APs, and the predownload functionality works as expected.

For detailed release recommendations, see the Guidelines for Cisco Wireless Software Release Migration Bulletin at: https://www.cisco.com/c/en/us/products/collateral/wireless/8500-series-wireless-controllers/bulletin-c25-738147.html

Table 4. Upgrade Path to Cisco WLC Software Release 8.3.122.0

Current Software Release

Upgrade Path to 8.3.122.0 Software

8.0.x

You can upgrade directly to 8.3.122.0.

8.2.x

You can upgrade directly to 8.3.122.0.

See the "Changes in Images and Installation Procedure for Cisco 2504 WLC, Cisco 5508 WLC, and Cisco WiSM2" section about special upgrade instructions for Cisco 2504 WLC, 5508 WLC, and WiSM2.

8.3.x

You can upgrade directly to 8.3.122.0.

  • 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.

  • 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 10 or a later version or Mozilla Firefox 32 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 8.3.122.0. 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 8.3.122.0 Cisco WLC software 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.

  • 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:

    Boot Options
    Please choose an option from below:
    1. Run primary image
    2. Run backup image
    3. Manually update images
    4. Change active boot image
    5. Clear Configuration
    Please enter your choice:

    Enter 1 to run the current software, enter 2 to run the previous software, enter 4 (on Cisco 5508 WLC), or enter 5 (on Cisco WLC platforms other than 5508 WLC) 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}

    Here:

    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.

  • 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 8.3.122.0 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

    • 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

    • Make changes to TCP MSS settings

Changes in Images and Installation Procedure for Cisco 2504 WLC, Cisco 5508 WLC, and Cisco WiSM2

Due to an increase in the size of the Release 8.3.122.0 Cisco WLC software image, the Cisco 2504 WLC, Cisco 5508 WLC, and Cisco WiSM2 software images are split into the following two images:

  • Base Install image, which includes the Cisco WLC image and a subset of AP images (excluding some mesh AP images and AP80x images) that are packaged in the Supplementary AP Bundle image

  • Supplementary AP Bundle image, which includes AP images that are excluded from the Base Install image. The APs that feature in the Supplementary AP Bundle image are:

    • AP802

    • Cisco Aironet 1530 Series AP

    • Cisco Aironet 1550 Series AP (with 64-MB memory)

    • Cisco Aironet 1550 Series AP (with 128-MB memory)

    • Cisco Aironet 1570 Series APs


Note

There is no change with respect to the rest of the Cisco WLC platforms.

The Cisco Mobility Express wireless network solution is available starting from Cisco Wireless Release 8.1.122.0.

The Cisco Mobility Express wireless network solution provides a wireless controller functionality bundled into the Cisco Aironet 1560, 1815, 1830, 1850, 2800, and 3800 Series access points.

In the Cisco Mobility Express wireless network solution, one AP, which runs the Cisco Mobility Express wireless controller, is designated as the Master AP. Other access points, referred to as Subordinate APs, associate to this Master AP.

The Master AP operates as a wireless controller, to manage and control the subordinate APs. It also operates as an AP to serve clients. The subordinate APs behave as normal lightweight APs to serve clients.

For more information about the solution, including the setup and configuration, see the Cisco Mobility Express User Guide for Release 8.3, at http://www.cisco.com/c/en/us/td/docs/wireless/access_point/mob_exp/83/user_guide/b_ME_User_Guide_83.html
