BPDU filter in Nortel

[Rajesh]

Hi,

Is Nortel BPDU filtering similar to Cisco BPDU guard?

 
In Nortel any bpdu receive on the bpdu filter enable port, the port gets blocked while in Cisco this feature only supported by BPDU guard command.

 
On the other hand bpd filter in cisco, filter the bpdu if any bpdu comes on port while sending or receiving.

Rgds,

BPDU Filtering blocks an unwanted root selection process when a device is added to the link and also blocks BPDU packets from ingressing the port

Hmmm... If I understand the question... are all packets blocked when BPDU guard is tripped?

I believe they are?

At least that's my assumption although I could be wrong. I had thought that Cisco behaves the same although I'll defer to anyone that has recently experience. If I recall the Cisco switch will put the port into an err-disable state.

It shouldn't be hard to test... or Google...

I know for fact that on ES470's, ERS4500 and ERS5500 devices. when bpdu gets tripped the whole port goes state_dis.
