I had configure the Cat3750 ports that are connecting AP1242  with BPDU guard .

I find out the ports will error disabled by "SPANTREE-2-BLOCK_BPDUGUARD: Received BPDU on port FastEthernet2/0/6 with BPDU Guard enabled. Disabling port";

It indicate the AP 1242 send out some BPDU packets to the switch. But I find out that all three physic interface (Dot11Radio0 / 1 / FastEhernet ) had configed with "bridge-group 1 spanning-disabled"

Where are these BPDU packsrts come from? How to slove this issue ?

Thank you !

Hi Hao,

you can just configure 3750 with bpdu filter enable command.

Alternatively, you can specify on the interface the command "no spanning-tree bpduguard enable".
