We currently have a switching topology in which two 7600 make up the core and there are N many access layer 4948s at the top of every few racks. They are trunked to both 7600s. I would like to migrate to a Nexus environment. My question is can Nexus series co-exist with 4948s?
From the documentation it seems as if it would be possible to create a vPC for each 4948 as in:
vPC1: 4948 rack 1 Te1/49 ---> Nexus1, 4948 rack 1 Te1/50 ---> Nexus2 vPC2: 4948 rack 2 Te1/49 ---> Nexus1, 4948 rack 2 Te1/50 ---> Nexus2 . . . vPCN: 4948 rack N Te1/49 ---> Nexus1, 4948 rack N Te1/50 ---> Nexus2
The current setup obviously leaves one of the Te's blocked by STP. Is that true (if this is possible) that the 4948s would utilize both Te interfaces since vPCs are non blocking?
Is this a viable setup?
