Command Usage
◆ The timeout configured by this command is set in the LACP timeout bit of the
Actor State field in transmitted LACPDUs. When the partner switch receives an
LACPDU set with a short timeout from the actor switch, the partner adjusts the
transmit LACPDU interval to 1 second. When it receives an LACPDU set with a
long timeout from the actor, it adjusts the transmit LACPDU interval to 30
seconds.
◆ 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
