Creating A Vpc Peer Link - Cisco Nexus 3548 Configuration Manual

Configuring Virtual Port Channels

Creating a vPC Peer Link

You can create a vPC peer link by designating the EtherChannel that you want on each switch as the peer link
for the specified vPC domain. We recommend that you configure the EtherChannels that you are designating
as the vPC peer link in trunk mode and that you use two ports on separate modules on each vPC peer switch
for redundancy.
Before you begin
Ensure that you have enabled the vPC feature.
You must configure both switches on either side of the vPC peer link
