interface port-channel

A port-channel interface is a logical interface that is created by aggregating multiple physical interfaces into a single logical interface. This allows for the use of multiple physical connections between devices to increase bandwidth and provide redundancy.

Port-channel interfaces are commonly used in networking technologies such as Ethernet and Fibre Channel. They are often referred to as link aggregation groups (LAG) or EtherChannel.

The configuration of a port-channel interface typically involves specifying the physical interfaces that will be used to form the channel, setting the channel protocol and mode, and configuring any additional settings such as load balancing or failover.

Once the port-channel interface is configured, it appears as a single interface to the rest of the network and can be used like any other interface for routing, switching, or other networking functions.
