DETAILED STEPS
Command or Action
Step 1
switch# configure terminal
Step 2
switch(config)# interface type

Step 3 switch(config-if)# channel-group
channel-number [force] [mode {on
| active | passive}]
Step 4
switch(config-if)# no channel-group
number mode
This example shows how to set the LACP-enabled interface to active port-channel mode for Ethernet interface
1/4 in channel group 5:
switch# configure terminal
switch (config)# interface ethernet 1/4
switch(config-if)# channel-group 5 mode active
This example shows how to forcefully add an interface to the channel group 5:
switch(config)# interface ethernet 1/1
switch(config-if)# channel-group 5 force
switch(config-if)#

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.
OL-25842-01
Purpose
Enters global configuration mode.
Specifies the interface to configure, and enters the interface configuration mode.
Specifies the port mode for the link in a port channel. After LACP is enabled, you
configure each link or the entire channel as active or passive.
force—Specifies that the LAN port be forcefully added to the channel group.
mode—Specifies the port channel mode of the interface.
active—Specifies that when you enable LACP, this command enables LACP on
the specified interface. The interface is in an active negotiating state in which the
port initiates negotiations with other ports by sending LACP packets.
on—(Default mode) Specifies that all port channels that are not running LACP
remain in this mode.
passive—Enables LACP only if an LACP device is detected. The interface is in
a passive negotiation state in which the port responds to LACP packets that it
receives but does not initiate LACP negotiation.
When you run port channels with no associated protocol, the channel mode is
always on.
Returns the port mode to on for the specified interface.
