Link Aggregation Commands 4

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

0

Command Mode

Interface Configuration (Ethernet Ports 1-8)

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, and will only take effect the next time an aggregate link is established with the partner.

Example

Console(config)#interface ethernet 1/5

Console(config-if)#lacp actor admin-key 120

Console(config-if)#

Syntax
