Command Mode

Command Usage
◆ Ports are only allowed to join the same LAG if (1) the LACP system priority
matches, (2) the LACP port admin key matches, and (3) the LACP port channel
key matches (if configured).
◆ If the port channel admin key (lacp admin key - Port Channel) is not set when a
channel group is formed (i.e., it has the null value of 0), the operational key is
set to the same value as the operational key of the first member port. Note that
when the LAG is no longer used, the port channel admin key is reset to 0.
Example
Console(config)#interface port-channel 1
Console(config-if)#lacp admin-key 3
