lacp port-priority
This command configures LACP port priority. Use the no form to restore
the default setting.
Syntax
lacp {actor | partner} port-priority priority
no lacp {actor | partner} port-priority
• actor - The local side an aggregate link.
• partner - The remote side of an aggregate link.
• priority - LACP port priority is used to select a backup link.
(Range: 0-65535)
Default Setting
32768
Command Mode
Interface Configuration (Ethernet)
Command Usage
• Setting a lower value indicates a higher effective priority.
• If an active port link goes down, the backup port with the highest
priority is selected to replace the downed link. However, if two or
more ports have the same LACP port priority, the port with the lowest
physical port number will be selected as the backup port.
• 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
