Command Usage
â—†
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.
â—†
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.
â—†
When a dynamic port-channel member leaves a port-channel, the default
timeout value will be restored on that port.
â—†
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)#
