per vlan spanning tree question
Posted on 2013-10-22
It's been a long time since I've had to deal with switches. I have a 3750 Stack (two 3750s) that is the root bridge for vlan x.
When I do a sh span vlan x, I get the below output:
Gi2/0/47 Desg FWD 4 128.101 P2p
Gi1/0/47 Root FWD 4 128.47 P2p
Both ports above trunk to a Nortel switch.
#1) It shows both ports as FWD. Does that mean both ports are actively sending traffic?
I believe the other side is just 1 Nortel switch. Would that Nortel switch block the port that connects to my cisco switch 2/0/47? My thoughts are that it would be active on the port connected to cisco switch 1/0/47 since that is marked as root and thus the best way to get to the root.
#2) question 2: If the Nortel switch has other mechanisms for loop avoidance and STP being one of them, should I automatically enable STP on the NOrtel?
