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.
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
-
We recommend you to perform the following procedure if you have the Cisco Smart License enabled and the Controller is registered on Cisco Smart Account.
Perform this procedure before upgrading the Cisco Controller's boot image.
-
Deregister the Cisco Controller running the old build from the Cisco Smart Software Manager (CSSM).
-
Upgrade the Cisco Controller with new boot image.
-
Reregister the upgraded Cisco Controller with new build on CiscoSmartSoftware Manager (CSSM).
-
-
When the Cisco controller is downgraded from 8.5.140.0 to 8.3.x release, it is possible that the OSU SSID profile name information may be lost and only the OSU SSID name is retained. Reconfigure the controller with the desired profile name to have the HotSpot 2.0 in action after downgrading the controller to 8.3.x release is complete.
-
In Release 8.5.135.0, the creation of Authorization server is deprecated. To create an Authorization server, you must create an Authentication server and duplicate it as an Authorization server. Due to this change in functionality, an alarm is generated in Cisco Prime Infrastructure 3.2 as follows:
1.Successfully created Authentication server. 2.Failed to create authorization server:SNMP operation to Device failed: Set Operation not allowed for TACACS authorization server.1.Successfully created Accounting server.
The workaround on Cisco PI is to uncheck the Authorization server on the Prime template.
For more information about this change in functionality, see CSCvm01415.
-
If you are using Release 8.4 and want to upgrade to a later release, it is necessary that you upgrade to Release 8.5.105.0 and then move to a later release.
Note
This restriction is applicable only to Release 8.4 and not any other release.
-
The image format of Cisco Aironet 1700, 2700, 3700, and IW3702 APs have been changed from ap3g2 to c3700. Therefore, if you are upgrading to Release 8.5 or a later release from Release 8.3 or an earlier release, these APs will download the image twice and reboot twice.
-
Support for Dynamic WEP is reintroduced in Cisco Wave1 APs in this release.
-
The AAA database size is increased from 2048 entries to 12000 entries for these Cisco controllers: Cisco 8510, 5520, and 8540. Therefore, if you downgrade from Release 8.5 to an earlier release that does not include this enhancement, you might lose most of the AAA database configuration, including management user information. To retain at least 2048 entries, including management user information, we recommend that you follow these downgrade instructions and back up the configuration file before proceeding with the downgrade:
-
From Release 8.5, downgrade to one of the following releases, which support 2048 database size and include the enhancement.
-
Release 8.4.100.0 or a later 8.4 release.
-
Release 8.3.102.0 or a later 8.3 release.
-
Release 8.2.130.0 or a later 8.2 release.
-
Release 8.0.140.0 or a later 8.0 release.
-
-
Downgrade to a release of your choice.
-
-
In Release 8.5, the search functionality in the Cisco controller Online Help for all controllers is disabled due to memory issues encountered in Cisco 5508 controllers.
-
Release 8.4 and later releases support 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 8.5 to Release 8.2 or an earlier release, the additional configuration option is invalidated and defaulted to FT disable. When you reboot Cisco controller 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 8.5 to a 7.x release, the trap configuration is lost and must be reconfigured.
-
If you downgrade from Release 8.5 to Release 8.1, the Cisco Aironet 1850 Series AP whose mode was Sensor before the downgrade 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 8.4 or a later release, ensure that you perform the following activities:
-
Enable IPv4 and DHCPv4 on the network—Load a new Cisco controller software image on all the Cisco controllers along with the supplementary AP bundle images on Cisco 5508 controller, or perform a predownload of AP images on the corresponding Cisco controllers.
-
Reboot Cisco controller immediately or at a preset time.
-
Ensure that all Cisco APs are associated with Cisco controller.
-
Disable IPv4 and DHCPv4 on the network.
-
-
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 controller to download a new image or to reboot Cisco controller after the download of the new image. You can forcefully reboot Cisco controller by entering the reset system forced command.
-
It is not possible to download some of the older configurations from Cisco 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 upgrade from Release 8.0.110.0 to a later release, the config redundancy mobilitymac mac-addr command's setting is removed. Manually reconfigure the mobility MAC address after the upgrade.
-
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.
-
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 controller intercepts it for redirection to the login page. If the HTTP GET request that is intercepted by the Cisco controller is longer than 2000 bytes, the Cisco controller drops the packet. Track CSCuy81133 for a possible enhancement to address this restriction.
-
We recommend that you install Cisco Wireless 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 or 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 about FUS and the applicable Cisco controller platforms, see the Field Upgrade Software release notes listing.
-
When downgrading from one release to another, you might lose the configuration from your current release. The workaround is to reload the previous Cisco controller configuration files that are saved in the backup server, or to reconfigure Cisco controller.
-
It is not possible to directly upgrade to this release from a release that is earlier than Release 7.0.98.0.
-
When you upgrade Cisco controller to an intermediate release, wait until all the APs that are associated with Cisco controller are upgraded to the intermediate release before you install the latest Cisco 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 Cisco 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 Cisco controller is also automatically upgraded. When an AP is loading software, each of its LEDs blinks in succession.
-
We recommend that you access the Cisco controller GUI using Microsoft Internet Explorer 11 or a later version, or Mozilla Firefox 32 or a later version.
-
Cisco controllers support standard SNMP MIB files. MIBs can be downloaded from the software download page on Cisco.com.
-
The Cisco controller software is factory installed on your Cisco controller and is automatically downloaded to the APs after a release upgrade and whenever an AP joins a Cisco 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 Cisco 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 Cisco 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.
-
-
When you plug a Cisco controller 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 5508 controller differs from the menu options for the other Cisco controller platforms.
The following is the Bootloader menu for Cisco 5508 controller:
Boot Options Please choose an option from below: 1. Run primary image 2. Run backup image 3. Change active boot image 4. Clear Configuration 5. Format FLASH Drive 6. Manually update images Please enter your choice:
The following is the Bootloader menu for other Cisco controller platforms:
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 of the respective Cisco controller platform for more details on running the bootup script and the power-on self test.
-
The Cisco 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, choose Option 2: Run Backup Image from the Boot Options menu to boot from the backup image. Then, upgrade with a known working image and reboot Cisco 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 Cisco controller.
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 controller or any AP during the upgrade process. If you do this, the software image might get corrupted. Upgrading Cisco controller with many 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 controller 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 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.
-
Changes in Images and Installation Procedure for Cisco 5508 Controllers
Due to an increase in the size of the Cisco controller software image, the Cisco 5508 controller software images are split into the following two images:
-
Base Install image, which includes the Cisco controller 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:
-
Cisco AP802
-
Cisco AP803
-
Cisco Aironet 1530 Series AP
-
Cisco Aironet 1550 Series AP (with 128-MB memory)
-
Cisco Aironet 1570 Series APs
-
Cisco Aironet 1600 Series APs
-
Note |
There is no change with respect to the rest of the Cisco controller platforms. |
Image Details
The following table lists the Cisco controller images that you have to download to upgrade to this release for the applicable Cisco controller platforms:
Cisco Controller |
Base Install Image |
Supplementary AP Bundle Image 1

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:
