The Admin Group defines the range of the ports that are going to be used by the EtherChannel. In Example 4-15, the Admin Group is 275, which covers the ports that fall in the range of 13-16. Ports 10/9-12 are configured as a channel using Admin Group 274. If a new EtherChannel needs to be configured on ports 10/11-14, two separate channels would form because the ports are part of two different Admin Groups. The Admin Group for an EtherChannel needs to be the same. The Admin Group can be reassigned with the following command in Example 4-16 to allow ports 10/11-14 to be in a single EtherChannel.
