AP'S are disassociating with ciscl wlc frequently

[guestme]

Hello Team,

we have three AP'S In a remote site.

All three WAP'S are disassociating with cisco wlc frequently.

when we checked using command show ap join stat summary,its showing AP'S last join error as echo failed.

what is possible reason as earlier there was no such issue.

That means that the WLC couldn't anymore talk to the AP.
This can be because of a bad connection or an overloaded one. How much latency do you have to the APs?
If they are in Flexconnect with activated office-extend, check it with 'show flexconnect office-extend latency '.

Hi mate,

It seems more of reachability issue.

You need to check your layer 2 - layer 3 connectivity between WLC and AP.

You can try and ssh to the AP as well and it will show you more info on the logs.

Thanks.

Cheers,

Raffy
