Information About vPC Operations
A vPC allows links that are physically connected to two different Cisco Nexus 5000 Series switches to
appear as a single port channel to a third switch. The third switch can be a Cisco Nexus 2000 Series
Fabric Extender or a switch, server, or any other networking device. A vPC can provide Layer 2
multipath capability which allows you to create redundancy by increasing bandwidth, enabling multiple
parallel paths between nodes, and load-balancing traffic where alternative paths exist.
For a quick overview of vPC configurations, see the Virtual PortChannel Quick Configuration Guide at
