Default Setting
Actor: Dependant on the port speed i.e. 1000f - 4, 100f - 3, 10f - 2 , Partner: 0
Command Mode
Interface Configuration (Ethernet)
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.
◆ 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.
Note: Configuring the partner admin-key does not affect remote or local switch
operation. The local switch just records the partner admin-key for user reference.
◆ By default, the actor’s operational key is determined by port's link speed
(1000f - 4, 100f - 3, 10f - 2), and copied to the admin key.
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.
