EtherChannel is the name that Cisco gives to its technology and architecture for link aggregation. EtherChannel is sometimes used interchangeably with the term PortChannel, which is the name of the virtual port created in a switch that binds the physical ports.
EtherChannel is a technology that lets you bundle multiple physical links into a single logical link. The bundle of physical links participating in the EtherChannel operates as a single logical interface.
This provides higher throughputs as well as redundancy in the event of a link failure.
