• 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
lacp admin-key (Port Channel)
This command configures a port channel's LACP administration key string.
Use the no form to restore the default setting.
Syntax

aggregation group (LAG) during local LACP setup on this switch.

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. Note
that when the LAG is no longer used, the port channel admin key is reset
to 0.
