We have two core switches at clients site.Both the core switches are connected to WAN individually.So there are two WAN circuits. There is also a link between the 2 core switches.
One of the core switch-1 catalyst 6509 is showing no traffic in MSFC on vlan interfaces although it has spanning tree forwardoing ports from the access switches and it is also HSRP active switch.
What i am seeing that traffic though comes on link to this switch from the access switch but then it goes to the other Core switch -2 using the link between and it exits to WAN.
There hardly any traffic that exits from Core switch-1. I have checked routes , both the core switches have same routes from MPLS provider.
Thanks in advance.
