To configure the LACP link mode, perform this task:
Command
Step 1
switch# configure terminal
Step 2
switch(config)# interface type
slot/port
Step 3
switch(config-if)# channel-group
number mode {active | on | passive}
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
Configuring the LACP System Priority and System ID
The LACP system ID is the combination of the LACP system priority value and the MAC address.
To configure the LACP system priority, perform this task:
Command
Step 1
switch# configure terminal
Step 2
switch(config)# lacp system-priority
priority
Step 3
switch(config-if)# show lacp
system-identifier
This example shows how to set the LACP system priority to 2500:
switch# configure terminal
switch(config)# lacp system-priority 2500
Configuring the LACP Port Priority
When you enable LACP, you can configure each link in the LACP EtherChannel for the port priority.
OL-16597-01
Purpose
Enters configuration mode.
Specifies the interface to configure, and enters the
interface configuration mode.
Specifies the port mode for the link in an EtherChannel.
After LACP is enabled, you configure each link or the
entire channel as active or passive.
When you run EtherChannels with no associated
protocol, the port-channel mode is always on.
The default port-channel mode is on.
Returns the port mode to on for the specified interface.
Purpose
Enters configuration mode.
Configures the system priority for use with LACP. Valid
values are 1 through 65535, and higher numbers have
lower priority. The default value is 32768.
Displays the LACP system identifier.
