Understanding the differences 04 mar 2013.
What is difference between vpc and port channel. Vpc virtual port channel. Vpc virtual port channel introduced in 2008 and is sometimes known as mec but it is actually an improvement to mec that serves the same functionality without having to use vss virtual switching system or stackwise. 3 vss can support l3 port channels across multiple chassis however vpc is used for l2 port channels only.
Vpc virtual port channel also known as multichassis etherchannel mec is a feature on the cisco nexus switches that provides the ability to configure a port channel across multiple switches i e. They actually combine the control and management planes of the member switches effectively turning them into one logical entity. However the key difference between vpc and vss is that vss creates a single logical switch.
Both stackwise and vss go far beyond just port channels. Virtual port channel vpc is a technology that has been around for a few years on the nexus range of platforms. Vpc is similar to virtual switch system vss on the catalyst 6500s.
