Vpc (Virtual Port Channel)
Similar to MEC (Multichassis Etherchannel) but for nexus switch however the difference is instead of having the VSS cluster acting as 1 physical switch, vPC (Virtual Port Channel) remains separate physical and logical entity
This will separate the Control Plane but single Data Plane (Forward Plane)
This feature is for Nexus switches but required vPC feature to be enabled.
Between the vPC peer switch there will be a peer keepalive link
