Finding the Cisco IOS Software Release

To find the version of Cisco IOS software running on your access point, use a Telnet session to log into the access point, and enter the show version EXEC command. This example shows command output from an access point running Cisco IOS Release 12.4(10b)JDA:

ap1240AG> show version
Cisco Internetwork Operating System Software
IOS (tm) C1240 Software (C1240-K9W7-M), Version 12.4(10B)JDA
Copyright (c) 1986-2008 by Cisco Systems, Inc.

On access points running Cisco IOS software, you can also find the software release on the System Software Version page in the access point's web-browser interface. If your access point does not run Cisco IOS software, the software release appears at the top left of most pages in the web-browser interface.

Upgrading to a New Software Release

For instructions on installing access point software for your access point:


Step 1 Follow this link to the Cisco home page:

Step 2 Click Product & Services. A drop-down menu appears.

Step 3 Click Wireless. The Wireless Introduction page appears.

Step 4 Scroll down to the Product Portfolio section.

Step 5 In the Access Point section, select the access point model for which you need the information. The Introduction page for the model you selected appears.

Step 6 Under the Support section, click Configure. A list of configuration documents appears.

Disable Radios to Prevent Unexpected Reboot When Upgrading System Software

If your access point runs Cisco IOS Release 12.2(11)JA, 12.2(11)JA1, or 12.2(11)JA2, your access point might unexpectedly reboot after you upgrade to a later Cisco IOS release. Because of a rare timing condition that affects the radios, the access point sometimes reboots immediately after the upgrade when the radios are enabled. However, after the access point reboots the upgrade is complete and the access point operates normally. To prevent the access point from rebooting unexpectedly, disable the radio interfaces before upgrading software.

Follow these steps to disable the radio interfaces using the web-browser interface:


Step 1 Browse to the Network Interfaces: Radio Settings page. Figure 1 shows the top portion of the Network Interfaces: Radio Settings page.

Figure 1 Network Interfaces: Radio Settings Page

Step 2 Select Disable to disable the radio.

Step 3 Click Apply at the bottom of the page.

Step 4 If your access point has two radios, repeat these steps for the second radio.


Beginning in privileged EXEC mode, follow these steps to disable the access point radios using the CLI:

 
Command
Purpose

Step 1 

configure terminal

Enter global configuration mode.

Step 2 

interface dot11radio {0 | 1}

Enter interface configuration mode for the radio interface. The 2.4-GHz radio is radio 0, and the 5-GHz radio is radio 1.

Step 3 

shutdown

Disable the radio port.

Step 4 

end

Return to privileged EXEC mode.

Step 5 

copy running-config startup-config

(Optional) Save your entries in the configuration file.

If your access point has two radios, repeat these steps for the second radio. Use the no form of the shutdown command to enable the radio.
