configure lacp member-port priority

configure lacp member-port port priority port_priority


Configures the member port of an LACP to ensure the order that ports are added to the aggregator. The lower value you configure for the port‘s priority, the higher priority that port has to be added to the aggregator.

Syntax Description

port Specifies the LACP member port that you are specifying the priority for.
port_priority Specifies the priority you are applying to this member port to be assigned to the LACP aggregator. The range is from 0 to 65535; the default is 0. The lower configured value has higher priority to be added to the aggregator.


The default priority is 0.

Usage Guidelines

The port must be added to the LAG (Link Aggregation Group) prior to configuring it for LACP. The default value is 0, or highest priority.

You can configure the port priority to ensure the order in which LAG ports join the aggregator. If you do not configure this parameter, the lowest numbered ports in the LAG are the first to be added to the aggregator; if there are additional ports configured for that LAG, they are put in standby mode.

Use this command to override the default behavior and ensure the order in which LAG ports are selected. Also, if more than one port is configured with the same priority, the lowest numbered port joins the aggregator.


The following command sets the port priority for the LAG port 5:1 to be 55 (which will probably put that port in standby initially):

configure lacp member-port 5:1 priority 55


This command was first available in ExtremeXOS 11.4.
