lacp admin-key
(Ethernet Interface)
This command configures a port's LACP administration key. Use the no form to
restore the default setting.
Syntax
lacp {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
belong to the same link aggregation group (LAG). (Range: 0-65535)
Default Setting
Actor: 1, Partner: 0
Command Mode
Interface Configuration (Ethernet)
Command Usage
â—† 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).
â—† 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.
â—† Once the remote side of a link has been established, LACP operational settings
are already in use on that side. Configuring LACP settings for the partner only
applies to its administrative state, not its operational state.
Example
Console(config)#interface ethernet 1/5
Console(config-if)#lacp actor admin-key 120
Console(config-if)#
lacp port-priority This command configures LACP port priority. Use the no form to restore the default
setting.
Syntax
lacp {actor | partner} port-priority priority
no lacp {actor | partner} port-priority
