I am trying to use BPDU guard feature but I am not able to make it work. I am configuring one switch port, with portfast (even in trunking mode), and I am enabling bpduguard feature. After this, I am connecting another switch to this port, which has stp enable, thus is sending BPDUs every 2 s (I have already tested it with sniffer), and as far as I know, the port from first switch should enter in errdisable state, but no way.
Can anyone help me?
Thanks in advance.
