◆ If the actor does not receive an LACPDU from its partner before the configured
timeout expires, the partner port information will be deleted from the LACP
group.
◆ When a dynamic port-channel member leaves a port-channel, the default
timeout value will be restored on that port.
◆ When a dynamic port-channel is torn down, the configured timeout value will
be retained. When the dynamic port-channel is constructed again, that timeout
value will be used.
Example
Console(config)#interface port-channel 1
Console(config-if)#lacp timeout short
Console(config-if)#
