vPC Overview
A virtual port channel (vPC) allows links that are physically connected to two different Cisco Nexus
7000 Series devices to appear as a single port channel by a third device (see Figure 7-1). The third device
can be a switch, server, or any other networking device that supports port channels. A vPC can provide
Layer 2 multipathing, which allows you to create redundancy and increase bisectional bandwidth by
enabling multiple parallel paths between nodes and allowing load balancing traffic.
