◆
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 port-priority 128
lacp system-priority
This command configures a port's LACP system priority. Use the

identifier. This identifier is used to indicate a specific LAG during LACP
negotiations with other systems.
