Information About Enhanced vPCs
Enhanced Virtual Port Channels Overview
The virtual port channel (vPC) feature allows the dual homed connection of a host to two fabric extenders
(FEXs) or a dual homed connection of a FEX to two switches. The enhanced vPC feature, or two-layer vPC,
allows both dual homing topologies to be combined simultaneously, as shown in the following figure:
Figure 13: Dual Homing Topology
With enhanced vPCs, all available paths from the hosts to the FEXs and from the FEXs to the switches are
active and carry Ethernet traffic, maximizing the available bandwidth and providing redundancy at both levels.
