Access Point 2702 Keeps booting

Susotelo — Mon, 05 Jul 2021 15:53:21 GMT

Hi!

I recently update the default gateway of my wireless infrastructure, when one of my access point reboot, it stopped works so I tried somethings to restart the AP but nothing worked so I decided to do a factory reset at the end of the reboot the access point started to rebooting all the time and keeps rebooting.

This is the main error that I saw Error opening flash:/capwap-saved-config (No such file or directory)

Hope you can help me. Thank you!

Try the command "clear capwap private-config" via CLI.

Make sure AP can ping AP and vice-versa.

Console into the AP and post the boot-up process. We want to see what is causing this issue.
What is the firmware version of the controller?

I did that is the PDF file.
I'm not pretty sure about the firmware, but I think is; C2700 Software (AP3G2-RCVK9W8-M)

I tried to do that but I can't. Check the video below please to see what happen with the AP.

I think I know what this is. The AP is running a firmware with a bug which sends BPDU to the switch. The switch then error-disables the port which causes the AP to lose power. There is an auto-recovery of an error-disabled port statement which then enables the port and the cycle repeats itself.

The only way to fix this is to go to the port and enter the command "spanning-tree bpduguard disable".

Refer to CSCur86600.

That almost works, but now the AP wait for more time to reboot.

I tried to connect to the WLC because the AP din't connect by itself. Please see the PDF to see the configuration.

This is the configuration of the switch port:

interface GigabitEthernet5/7
description Port 278 AP
switchport access vlan 10
switchport mode access
spanning-tree bpduguard disable
end

Thank you.

Two issues, first the very old image of LWAPP image version 8.0.115.0, but it should still work with this.
Second issue, it seems the AP has some old invalid configuration, I suggest you reset it by using the reset button on the device. Here you find details: https://popravak.wordpress.com/2014/08/26/resetting-cisco-capwaplwap-access-point-to-factory-defaults/
