LACP configuration guidelines

Consider the following guidelines when you configure LACP trunks:

„When ports become members of a trunk, configuration parameters (except ACL and QoS) are applied per trunk. When a trunk group is formed, these parameters are configured for the trunk ID, which overrides the port-level parameters.

„The range of potential LACP trunk IDs is 53-104.

„When a LACP trunk forms, the trunk ID is determined by the lowest port number in the trunk. For example, if the lowest port number is 1, then the LACP trunk ID is 53.

„The LACP trunk ID can change if the link is lost on the lowest port in the group. When the trunk ID changes, trunk-level parameters are cleared. To avoid losing configuration parameters, configure LACP trunk-level parameters for all possible trunk IDs. Use the port range configuration mode to set parameters for all of the ports that might participate in LACP.

„When a port becomes a member of a LACP trunk, LACP overrides the individual port configuration.

„If the port leaves the LACP trunk, you must reconfigure the port settings.

„Each port that is configured to participate in LACP must be set to full duplex.

Configuring LACP

Use the following procedure to configure LACP on ports 2-6 to participate in link aggregation.

1.Configure port parameters. All ports that participate in the LACP trunk group must have the same settings, including VLAN membership.

2.Select a range of ports and define the admin key. Only ports with the same admin key can form a LACP trunk group.

RS G8000 (config)# interface port 2-6

RS G8000 (config-if)# lacp key 100

3.Set the LACP mode.

RS G8000 (config-if)# lacp mode active

RS G8000 (config-if)# exit
