Controller c9800 AP 9120AXI stuck in operation state downloading

GiuseppeCarmine — Mon, 05 Jul 2021 19:45:50 GMT

Hello everyone,

I'm trying to register two APs 9120AXI to a c9800.

c9800 software version: Cisco IOS XE Software, Version 16.12.04a

AP, current software version: Cisco AP Software, ap1g7-k9w8 Version: 8.10.105.0

It has been two days already, and the APs are still in downloading.

I have no access to the APs through ssh.

Any suggestions?

Reboot the AP’s is your only solution. Shut down the PoE.

connect a console cable to the AP to check console logging.
we experienced some issues where the new software was successfully downloaded to the AP,
but the boot-variable was not correctly changed to the new version. the AP then reloads with the AP recovery image.
this can be recognized by "RCVR" in the booted image name like: Loading "flash:/ap3g2-rcvk9w8-mx/ap3g2-rcvk9w8-mx"
this cycle download image -> boot -> load recovery image keeps repeating!
solutions are
- boot into rommon
change the boot variable
set (display all variables)
set BOOT ..... (variable name in capitals!)
boot
- boot into rommon
manually boot the correct image
- boot into AP OS (recovery image)
login with cisco Cisco
debug capwap console cli (hidden command to enable local config changes)
re-config boot variable
show boot
conf t
no boot .....
boot system .....
end (NB! no need to write because boot variable is not stored in the startup-config on flash but in NVRAM)
NB! you need to complete this within the timeout before it reloads automatically
reload

Hello Scott,

isn't that risky when you are downloading the OS from the controller?

Hello Pieterh,

Is there any command I can run on the controller to verify it?

It won't be easy to get console access from that remote site but I'll try.

Thanks

Not at all. I’ve done that many times when stuck.

first: it can be seen on the switchport, you can see the port going up/down repeatedly as the AP reboots
and with show cdp neighbors <interfacename> detail (repeat multiple times) you can see what image is active

second: when you copy the MAC address from above info you can start a debug on the controller
troubleshooting -> radioactive trace -> add mac address of AP -> start (if not allready started)
after 10-15 minutes download the logs and look for confirmation if this situation occurs
