What's New in Release

This section provides a brief introduction to the new features and enhancements that are introduced in this release.


For complete listing of all the documentation published for Cisco Wireless Release 8.9, see the Documentation Roadmap:


Cisco Catalyst 9100 Access Points

The Cisco Catalyst 9100 Access Points are IEEE 802.11ax standard compliant APs. The 802.11ax standard allows access points support more clients in dense environments and provides a better experience for typical wireless LAN networks. The 802.11ax standard also provides a more predictable performance for advanced applications such as 4K or 8K video, high-density high-definition collaboration applications, all-wireless offices, and Internet of Things (IoT).

Wi-Fi 6 Features

OFDMA Support for 802.11ax APs: Using the OFDMA technology, the Cisco 9100 APs support eight spatial streams and deliver up to 4800-Mbps throughput at the physical layer. OFDMA-based channel access is backward-compatible with traditional EDCA/CSMA, and Cisco 9100 access points use each channel optimally.

MU-MIMO: Provides concurrent downstream communications to multiple wireless devices for more efficient use of the spectrum.

Target Wake Time (TWT): The TWT feature reduces the network energy consumption through better scheduling and spectrum optimization. Devices enter a doze state until their TWT arrives, thereby significantly increasing battery run time, an important requirement for IoT devices.

1024 Quadrature Amplitude Modulation (QAM): The QAM feature increases throughput in Wi-Fi devices by encoding more data in the same amount of spectrum.


For more information about feature support in 802.11ax APs, see Feature Matrix for Cisco Wave 2 Access Points and Wi-Fi 6 (802.11ax) Access Points.

Power Requirements

  • We recommend that you pair the Cisco Catalyst 9115 APs with an 802.3at PoE-capable switch to get the best performance from these APs. If the power supply is not 802.3at-capable, there is a drop in performance that is related to Tx power and spatial streams.


    Under critically low power conditions, the AP LED might blink in a loop of red, blue, and green color, and the controller GUI summary page might display power supply as medium power.
  • We recommend that you pair the Cisco Catalyst 9117 APs with an UPoE switch. This allows the external USB module to be attached to the USB port on the APs.


The following 802.11ax AP models are supported:

Upgrading 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

  • 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.

  • On executing the show tech-support command on a Cisco 9100 AP, if the displayed result is empty, as a workaround, logout and relogin to the same access point using SSH and run the command. For more information, see CSCvo28881.

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

  • If you are upgrading from Release 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.

  • 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.

  • If you are downgrading from Release 8.9 to an earlier release, any local policy to WLAN ID mapping wherein the local policy ID is greater than 255 is lost after the downgrade. If necessary, you can modify the policy mapping so that a local policy whose ID is greater than 255 is not used.

    You can check for the local policy ID in either of the following ways:

    • CLI: Enter the show policy summary command.

    • GUI: Navigate to Security > Local Policies. On the Policy List page, the policy ID is displayed along with the policy name.

  • 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.


    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.


      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 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:
