· An Ether Channel is the aggregation of multiple physical channels into a single logical connection.
· The single logical connection is referred to as a port channel.
· You can configure the port channel to operate as a Layer 3 interface on some switches.
· When assigned with an IP address, the port channel becomes the logical Layer 3 interface.
· If any single link of the channel fails, the port channel interface is still accessible through the other links.
· Layer 3 Ether Channel operation is the same as Layer 2 Ether Channels for traffic distribution and channel establishment.
