Re: Bpdu issues

Hi Mustafa!!

I enabled both features just to check what the result would be.
When a BPDU came into the access-port, the port went to err-disable, so the
BPDU Guard feature wins.

I'm not sure if it's useful to enable both features in global config. BPDU
Filter stops sending BPDUs (but and access-port doesnt send BPDUs anyway)
and make the port loose its portfast condition if it receives a BPDU.
On the other hand, BPDU Guard doesnt make a port to stop sending BPDUs
(doesnt matter when the port is an access-port, because it already doesnt
send them) but it makes the port to shut down if it receives a BPDU.

So, why to enable both features in global config?? I would config only BPDU
Guard.

Experts, do you see any reason to do it??
