Firmware FAQs and Troubleshooting
Note Do not make this value extremely high. It is advisable to keep this value to something slightly higher than the actual reboot time of the slowest access point.
Symptom Firmware jobs over slow links do not succeed.
Possible Cause The access points being upgraded are connected to the WLSE over a slow link (less than 1.544 Mbps) and the job is timing out.
Caution Do not take the following action for firmware jobs that you are running to convert
Recommended Action
a.Access the WLSE through the following URL: http://your_wlse:1741/debug/jobprops.jsp
b.Increase the value of the Per device job operation timeout parameter. For example, for a 56kbps link, the recommended value is 2400 seconds (40 minutes). On a 128kbps link, the recommended value is 1200 seconds (20 minutes).
Symptom A conversion job fails because the firmware installation does not start.
Possible Cause The AP may not have enough free memory. A minimum of 4 MB (DRAM) of free space is required for the conversion to succeed.
Recommended Action To check the free space available, use the CLI command :vxdiag_memshow. You can temporarily remove the 11a radio to free up space. For more information, see the access point documentation on Cisco.com.
