Cisco AP send BPDU on Cisco Switch?

Hi All,

We have a Cisco AP AIR-AP2802(18.5) typical flexconnect setup which connected on managed switch which have a BPDU guard enabled and the issue is that recently we can see that the AP send BPDU causing the interface to get disabled which result connection issue which clients connected to that AP.

Seen that this mostly due to bug on the current AP version but we have multiple site using this same AP model and version but only a single site getting this issue and note that we just recently encountered this and this happens on a random time/day.

question:

1. Is it possible that the wireless client (laptop,ipphones,mobile) can forward/genarate a BPDU to AP then AP forward the BPDU message to switch?

2. If #1 is true, How can we prevent this and identify which host mac address sending the BPDU messages?

3. Is is possible to filter,block,disable the BPDU on AP?

   Thank you
