Configuring the LACP Fast Timer Rate
You can change the LACP timer rate to modify the duration of the LACP timeout. Use the lacp rate
command to set the rate at which LACP control packets are sent to an LACP-supported interface. You
can change the timeout rate from the default rate (30 seconds) to the fast rate (1 second). This command
is supported only on LACP-enabled interfaces.
BEFORE YOU BEGIN
Ensure that you have enabled the LACP feature.
Ensure that you are in the correct VDC (or use the switchto vdc command).

This example shows how to configure the LACP fast rate on Ethernet interface 1/4:
switch# configure terminal
switch (config)# interface ethernet 1/4
switch(config-if)# lacp rate fast
This example shows how to restore the LACP default rate (30 seconds) on Ethernet interface 1/4.
switch# configure terminal
switch (config)# interface ethernet 1/4
switch(config-if)# no lacp rate fast
