what will be the problem of AP keep rebooting?

[Leo Laohoo]

what will be the problem of AP keep rebooting?

Not sure until someone can console into the AP.  

[ljustl]

I tried factory reset, (pressing button while i'm connecting)

set the times correctly.. i don't know where else to start..

[Leo Laohoo]

Can you console into the AP and leave the console session alone? 

We want to see what triggers the AP to reload/reboot independently.  

[ljustl]

that error messages are above.

thats the only messages i saw so far. same thing over and over and over

as you see, AP gets the time wrong and gets to fix later to current it does its own stuff and keep rebooting...

[Leo Laohoo]

I need to see the lines in the console terminal.  I can't help troubleshoot if I don't see them.

[ljustl]

do you need to see certain command from AP's CLI?

i've attached error messages..

[Leo Laohoo]

I can see the AP boot up, get an IP address, joined the controller, receive the IOS file from the controller and reboot. 

From the look of things, I don't see any problem. 

Are you seeing the AP downloading the IOS and reboot over and over again?

[ljustl]

Are you seeing the AP downloading the IOS and reboot over and over again?

- Yes..

[Leo Laohoo · Accepted solution]

- Yes..

Reboot your controller.

[ljustl]

I will reboot and let you know!

[ljustl]

Well... i did reboot my controller and i was able to console in and login to the AP

HOWEVER.... AP is keep rebooting itself. I confirmed that AP is joined in controller as well, but it keep rebooting automatically. Refer below...

[ljustl]

now i found out why

port is flapping.... IEEE PD on "show power inline" command.....

this was reason why AP were keep rebooting itself.

[Leo Laohoo]

port is flapping

If the port was flapping then the AP wouldn't be downloading the IOS over and over again.  

But let's move forward, is the switch connected to the AP a Cisco switch?  If it is, can you tell me the model and IOS version?

[ljustl]

maybe i stated wrong. but it was getting power and suddenly stopped. i found out it IEEE PD.
