I understand teh use of these commands as per the cisco and various other documents. However, there are still few unclear spots.
1-When filter option is ebnabled on port level, teh port is no longer part of SPT and BPDU's are filtered ( In/out). If u receive a BPDU from a misconfigured device, port looses it's portfast status...but why does is this happen in 1st place if BPDU's are filtered ?
2-Once BPDUs are received and portfast status lost, do u then keep on receiving BPDUs...unless Guard option is on to disable the port ?
3-On RSTP, and edge port is on portfast, what happens when the port receives a BPDU and filter is on. What show i see in spanning -tree port definition P2P ?
Links would be great, the existing ones are a repeat of main definition and guidelines of the command.
It is obvious that Filter on its own is not enough.
