About PortChannels
PortChannels refer to the aggregation of multiple physical interfaces into one logical interface to provide
higher aggregated bandwidth, load balancing, and link redundancy (See Figure 23-1). PortChannels can
connect to interfaces across switching modules, so a failure of a switching module cannot bring down
the PortChannel link.
