Hi,

When STP is disabled on E-Series, the box seems to discard the BPDUs
received on it's interfaces(layer 2 switch port mode).
Can I configure the box to pass through (flood) the multicast destined for
mac address "01:80:c2:00:00:00"?

[bridge]---BPDU(A)--> gi1/0 [E-series(STP disabled)] gi1/1 ---BPDU(A)--->

#show cam mac linecard 0 port-set 0
:
Index Table ID VlanId Mac Address Region Interface
:
28668 0 0 01:80:c2:00:00:00 BLACKHOLE 01c05
:

TIA

Your observation is correct. Current behavior is to consume the BPDUs in
the situation you describe.

There currently is no option to change this behavior.

Hope this helps.

Ron,

So, I will enable STP on the E-box.

Thanks!
