[j-nsp] TCN guard on Juniper EX

[Dennis Hagens]

Hi All,

Is there some way to filter out STP TCN BPDU's on a Juniper EX series switch?

We have some old Netgears in our office environment (yes, I need to get rid of those) which send TCN's on edge port flaps.
This causes a lot of reconvergence / mac table flushes on our datacenter switches, which are connected via layer 2 with the office. We currently hooked up an HP switch with TCN  guard to mitigate this, but this introduces a SPOF.

Any ideas?

Thanks,

Dennis Hagens
