> # Interfaces in a PortChannel

> You can add or remove a physical interface (or a range of interfaces) to an existing PortChannel. The compatible parameters on the configuration are mapped to the PortChannel. Adding an interface to a PortChannel increases the channel size and bandwidth of the PortChannel. Removing an interface from a PortChannel decreases the channel size and bandwidth of the PortChannel.

> This section describes interface configuration for a PortChannel and includes the following topics:

> - Interface Addition to a PortChannel
> - Forcing an Interface Addition
> - Interface Deletion from a PortChannel

> Note For information about PortChannel support on Generation 2 switching modules, see the "PortChannel Limitations" topic.
