Introduction

Cisco Wireless LAN Controller (WLC) Field Upgrade Software (FUS) is a special AES package that performs various system-related component upgrades. We recommend that you install the FUS image to upgrade components such as the bootloader, field recovery image, FPGA/MCU, and other firmware to their latest respective versions.

Table 1 lists the components that are upgraded after you install Field Upgrade Software for various controller platforms.

 

 

Downloading Field Upgrade Software

---

Step 1 Go to the Cisco Software Center at this URL: https://software.cisco.com/download/navigator.html

Step 2 Choose Products > Wireless > Wireless LAN Controller.

Step 3 Choose either of the following depending on the controller platform you use:

• Integrated Controllers and Controller Modules
• Standalone Controllers

Step 4 Choose the controller model number or name. The Download Software page is displayed.

Step 5 Choose Wireless LAN Controller Software.

Step 6 Click a controller software release. The software releases are labeled as follows to help you determine which release to download:

• Early Deployment (ED) —These software releases provide new features and new hardware platform support as well as bug fixes.
• Maintenance Deployment (MD) —These software releases provide bug fixes and ongoing software maintenance.
• Deferred (DF) —These software releases have been deferred. We recommend that you migrate to an upgraded release.

Step 7 Click a software release number. Click the filename (for example, AIR-CT5500-K9-1-9-0-0-FUS.aes). The following AES files are available for various controller platforms:

– AIR-CT5500-K9-1-9-0-0-FUS.aes

– AIR-CT5500-LDPE-1-9-0-0-FUS.aes

– AIR-CT7500-K9-1-9-0-0--FUS.aes

– AIR-WISM2-K9-1-9-0-0-FUS.aes

– AIR-CT2500-K9-1-8-0-0-FUS.aes

Step 8 Click Download.

Step 9 Read Cisco’s End User Software License Agreement and then click Agree.

Step 10 Save the file to your hard drive.

Step 11 Copy the AES file (for example AIR-CT5500-K9-1-9-0-0-FUS.aes) to the default directory on your TFTP or FTP server.

Upgrading FUS Image

---

Step 1 Upload your controller configuration files to a server to back them up.

Step 2 Get the controller software image as defined in Downloading Field Upgrade Software, and follow these steps:

a. Choose Wireless > Wireless LAN Controller. The following options are available: Integrated Controllers and Controller Modules and Standalone Controllers.

b. Depending on your controller platform, click one of the above options.

c. Click the controller model number or name. The Download Software page is displayed.

d. Click a controller software release. The software releases are labeled as follows to help you determine which release to download:

– Early Deployment (ED) —These software releases provide new features, new hardware platform support, and bug fixes.

– Maintenance Deployment (MD) —These software releases provide bug fixes and ongoing software maintenance.

– Deferred (DF) —These software releases have been deferred. We recommend that you migrate to an upgraded release.

e. Choose a software release number.

f. Click the filename (for example, AIR-CT5500-K9-1-9-0-0-FUS.aes).

g. Click Download.

h. Read Cisco’s End User Software License Agreement and then click Agree.

i. Save the file to your hard drive.

j. Repeat steps a through k to download the remaining file.

Step 3 Copy the controller software image (filename.aes) to the default directory on your TFTP or FTP server.

Step 4 (Optional) Disable the 802.11 networks.

---

Note For busy networks, controllers on high utilization, or small controller platforms, we recommend that you disable the 802.11 networks as a precautionary measure.

Step 5 Disable any WLANs on the controller.

Step 6 Choose Commands > Download File to open the Download File to Controller page.

Step 7 From the File Type drop-down list, choose Code.

Step 8 From the Transfer Mode drop-down list, choose from the following options:

• TFTP
• FTP

Step 9 In the IP Address text box, enter the IP address of the server.

If you are using a TFTP server, the default values of 10 retries and 6 seconds for the Maximum Retries and Timeout text boxes should work correctly without any adjustment. However, you can change these values.

Step 10 If you are using a TFTP server, the default values of 10 retries for the Maximum Retries text field, and 6 seconds for the Timeout text field should work correctly without any adjustment. However, you can change these values if desired. To do so, enter the maximum number of times that the TFTP server attempts to download the software in the Maximum Retries text box and the amount of time (in seconds) that the TFTP server attempts to download the software in the Timeout text box.

Step 11 In the File Path text box, enter the directory path of the software.

Step 12 In the File Name text box, enter the name of the controller software file (for example, AIR-CT5500-K9-1-9-0-0-FUS.aes).

Step 13 If you are using an FTP server, follow these steps:

• In the Server Login Username text box, enter the username to log into the FTP server.
• In the Server Login Password text box, enter the password to log into the FTP server.
• In the Server Port Number text box, enter the port number on the FTP server through which the download occurs. The default value is 21.

Step 14 Click Download to download the software to the controller. A message appears indicating the status of the download.

Step 15 After the download is complete, click Reboot.

Step 16 If prompted to save your changes, click Save and Reboot.

Step 17 Click OK to confirm.

Step 18 After the controller reboots, repeat step 6 to step 17 to install the remaining file.

Step 19 Reenable the WLANs.

Step 20 For Cisco WiSM2, reenable the controller port channel on the Catalyst switch.

Step 21 If you have disabled the 802.11 networks in Step 4, reenable them.

Step 22 To verify the controller software version, choose Monitor on the controller GUI and see Software Version in the Controller Summary area.

 

Caveats

The following sections lists Open Caveats and Resolved Caveats for Cisco controllers and lightweight access points for version 1.9.0.0. For your convenience in locating caveats in Cisco’s Bug Toolkit, the caveat titles listed in this section are drawn directly from the Bug Toolkit database. These caveat titles are not intended to be read as complete sentences because the title field length is limited. In the caveat titles, some truncation of wording or punctuation might be necessary to provide the most complete and concise description. The only modifications made to these titles are as follows:

• Commands are in boldface type.
• Product names and acronyms might be standardized.
• Spelling errors and typos might be corrected.

If you need information about a specific caveat that does not appear in these release notes, you can use the Cisco Bug Toolkit to find caveats of any severity. Click this URL to browse to the Bug Toolkit:
