LACP CONFIGUATION CISCO NEXUS SWITCH
LACP supports two modes: Active and Passive. The Active mode initiates the negotiation by sending LACP packets to the connected device, while the Passive mode waits for the other end to initiate the negotiation. By default, Cisco Nexus switches are configured in the Active mode. To change the mode, use the following command:
switch# configure terminal
switch(config)# interface Ethernet1/1
switch(config-if)# lacp mode [active | passive]
Configure LACP on Cisco Nexus Switch
To configure LACP on a Cisco Nexus switch, follow the steps below:
Step 1: Enable the feature set
switch# configure terminal
switch(config)# feature lacp
Step 2: Create an EtherChannel
switch# configure terminal
switch(config)# interface port-channel1
Step 3: Configure the member interfaces
switch(config-if)# interface Ethernet1/1
switch(config-if)# channel-group 1 mode active
switch(config-if)# exit
switch(config-if)# interface Ethernet1/2
switch(config-if)# channel-group 1 mode active
switch(config-if)# exit
Step 4: Verify the configuration
The output of the command will show the status of the LACP negotiation between the Nexus switch and the connected device.
Conclusion
LACP is an important protocol for aggregating multiple links into a single logical link, which improves network performance, enhances redundancy, and increases bandwidth. Configuring LACP on a Cisco Nexus switch is a simple process, but it requires attention to detail to ensure that the EtherChannel is properly configured and functioning as expected. By following the steps outlined in this article, network administrators can configure LACP on Cisco Nexus switches with confidence.
