DRAFT: BROCADE CONFIDENTIAL
switch(config)#interface tengigabitethernet 0/1
switch(conf-if-te-0/1)#lacp timeout short
switch#clear lacp 42 counters
switch#clear lacp counters
Make sure that both ends of the link are configured as standard for the trunk type.
Make sure that both ends of the link are not configured for passive mode. They must be
configured as either active/active, active/passive, or passive/active.
Make sure that the port-channel interface is in the administrative "up" state by ensuring that
the no shutdown command was entered on the interface on both ends of the link.
Make sure that the links that are part of the LAG are connected to the same neighboring
switch.
Make sure that the system ID of the switches connected by the link is unique. This can be
verified by entering the show lacp sys-id command on both switches.
