Configured LACP MAC is the configured LACP MAC using the:

configure {mlag peer} peer_name lacp-mac lacp_mac_address

command.

If no MAC is configured,

Config'd LACP MAC

is shown as None.

If same LACP MAC is configured on both the switches, the current LACP MAC will be the same as

Config'd LACP MAC.

If LACP MAC is not configured on any of the MLAG peers or if a different MAC is configured on the peers,

Current LACP MAC

is different from Config'd LACP MAC and is selected from Local MAC/Peer MAC combination.

History

This command was first available in ExtremeXOS 12.5.
