In a dual 6509 setup, is it possible to know which trunk interface is involved in the communication between the two 6509 switches?
Lets say for example that I have three individual trunk links going between the 6509's. Can I know over which link is the communication happening OR which link is currently active and passing packets between the switches? The reason I am asking this question is because I am seeing three links between the two 6509's and all are configured for VLAN pruning except one.
And there is only one trunk link where all VLAN's are allowed and I want to make sure that that is the one being used.
The spanning tree mode is PVST if that might help.
Thanks and Regards
