User Guidelines
The LACP time-out setting indicates a local preference for the rate of
LACPDU transmission and the period of time before invalidating received
LACPDU information. This setting is negotiated with the link partner. Long
time-outs are 90 seconds with a transmission rate of once every 30 seconds.
Short time-outs are 3 seconds with a transmission rate of once every second.
For further information, refer to the LACP_Timeout setting in IEEE Std.
802.1AX-2008.
Example

Gi1/0/8 to a long timeout value.

port-channel local-preference
Use the port-channel local-preference command in Interface Configuration
mode to enable the local-preference mode on a port-channel (LAG) interface
or range of port-channel interfaces.
