vPC best practices indicate to use a minimum of 2 x 10GE ports for the peer-link. I am trying to determine if I should use the minimum (2x 10GE ports) or use more ports for my design.
I have about 50 access switches separated into about 10 stacks. Each stack has 4 x 10GE uplinks to the Nexus 7700 VPC domain (2x 10GE links to each nexus switch). If the access switch uplink bandwidth is 40 GE then would having only 2 x 10GE for the peer-link be considered okay? What is the best practice in terms of uplink bandwidth to peer-link bandwidth (2:1, 1:1 or 1:2)? I have done VSS before and used 1:2 access switch uplink to vss bandwidth.
