Chapter Description

Port Channel technology allows multiple links between two participating devices to be used to forward traffic by using a load-balancing algorithm. vPC (virtual port channel) technology allows multiple devices to form a port channel. In this sample chapter from Cisco Data Center Fundamentals, the authors discuss Ethernet port channels, including port channel modes, port channel compatibility requirements, and port channel load balancing.
