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)
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)#
