Updating the Operating System SoftwareUpdating the Operating System Software
When you plan to update the Cisco Wireless LAN Controller (and Cisco 1000 Series lightweight access
point) Operating System software, complete the following.
• Be sure you have a TFTP server available for the Operating System software download.
- If you are downloading through the Service port, the TFTP server MUST be on the same
subnet as the Service port, because the Service port is not routable.
- If you are downloading through the DS (Distribution System) network port, the TFTP
server can be on the same or a different subnet, because the DS port is routable.
• Download the desired Operating System software update file from the Cisco SWAN website to
the default directory on your TFTP server.
- Starting with Release 1.2.52.4, the Operating System code update file is a .aes
(compressed) file. Refer to the Upgrading to Operating System Release 1.2 Technical
Bulletin for instructions to update the Cisco Wireless LAN Controller from a .tgz to
a .aes format.
- The Operating System code update file is named AS_2000_2_2_x_x for Cisco 2000
Series Wireless LAN Controllers, or AS_4100_2_2_x_x for Cisco 4100 Series Wireless
LAN Controllers. Note that the Cisco SWAN can be updated or reverted between the 2.0
and 2.2 OS releases.
• Refer to the Using the Cisco SWAN CLI section to connect and use the CLI.
• In the CLI, use the ping <IP Address> command to ensure the Cisco Wireless LAN Controller
can contact the TFTP server.
• In the CLI, use the transfer download start command, and answer ‘n’ to the prompt, to view
the current download settings:
>transfer download start
Mode........................................... TFTP
Data Type...................................... Code
TFTP Server IP................................. xxx.xxx.xxx.xxx
TFTP Path...................................... <directory path>
TFTP Filename.................................. AS_2000_2_2_60_0.aes --or--
AS_4100_2_2_x_x
Note: You can start the Operating System software update using the Web User
Interface, Cisco WCS User Interface, or Management over Wireless. However, in all
three cases, you will lose your connection to the Cisco Wireless LAN Controller some
time during the update process. For this reason, Cisco SWAN strongly recommends
that you use a direct CLI Console Port connection to update the Operating System
software.
Note: On the Cisco 2000 Series Wireless LAN Controller, the TFTP server MUST be on
the same subnet because this switch does not have a service port.
Note: The TFTP server cannot run on the same computer as the Cisco Wireless
Control System, because Cisco WCS and the TFTP server use the same communica-
tion port.
