Configuring Port Channels
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).
SUMMARY STEPS
1. configure terminal
2. interface type slot/port
3. lacp rate fast
DETAILED STEPS
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
Configuring the LACP System Priority
The LACP system ID is the combination of the LACP system priority value and the MAC address.
Command or Action Purpose
Step 1
configure terminal
Example:
switch# configure terminal
switch(config)#
Enters configuration mode.
Step 2
interface type slot/port
Example:
switch(config)# interface
ethernet 1/4
Specifies the interface to configure and enters the interface
configuration mode.
Step 3
lacp rate fast
Example:
switch(config-if)# lacp rate
fast
Configures the fast rate (one second) at which LACP control
packets are sent to an LACP-supported interface.
To reset the timeout rate to its default, use the no form of the
command.
