Use the no form torestore the default setting.Syntaxlacp {actor | partner} admin-key key[no] lacp {actor | partner} admin-key• actor - The local side an aggregate link.• partner - The remote side of an aggregate link.• key - The port admin key must be set to the same value for ports that belongto the same link aggregation group (LAG). (Range: 0-65535)Default Setting0Command ModeInterface Configuration (Ethernet)Command Usage• Ports are only allowed to join the same LAG if (1) the LACP system prioritymatches, (2) the LACP port admin key matches, and (3) the LACP portchannel admin key matches (if configured).• If the port channel admin key (lacp admin key - Port Channel) is not set whena channel group is formed (i.e., it has the null value of 0), this key is set to thesame value as the port admin key (lacp admin key - Ethernet Interface) usedby the interfaces that joined the group.• Once the remote side of a link has been established, LACP operationalsettings are already in use on that side. Configuring LACP settings for thepartner only applies to its administrative state, not its operational state, andwill only take effect the next time an aggregate link is established with thepartner.ExampleConsole(config)#interface ethernet 1/5Console(config-if)#lacp actor admin-key 120Console(config-if)#
