key -The port channel admin key is used to identify a specific link aggregation group (LAG) during local LACP setup on
this switch. (Range: 0-65535)
Default Setting
0
Command Mode
Interface Configuration (Port Channel)
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), this key is set to the same value as the port admin key (lacp admin key - Ethernet Interface) used by the
interfaces that joined the group. 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 actor admin-key 3
Console(config-if)#

two or more ports have the same LACP port priority, the port with the lowest physical port number will be selected as the
