Defining an EtherChannel Administrative Group

You can define an EtherChannel administrative group manually to identify groups of ports that are
allowed to form an EtherChannel bundle together. When you create an EtherChannel port bundle, an
administrative group is defined automatically. Administrative group membership is limited by hardware
restrictions.
The admin_group can be any value between 1 and 1024, inclusive.
Caution Modifying the EtherChannel administrative group on connected ports causes the specified ports to be
removed from and then added to spanning tree (that is, a spanning tree topology change occurs and the
ports must enter listening and learning mode before returning to forwarding mode).
To define an EtherChannel administrative group, perform this task in privileged mode:
Task
Step 1 Define the administrative group by specifying the
ports in the group.
Step 2
Verify the administrative group configuration.
This example shows how to assign ports to an administrative group and verify the configuration:
Console> (enable) set port channel 3/5-6 50
Port(s) 3/5-6 are assigned to admin group 50.
Console> (enable) show channel group 50
