How to Configure VPC on Cisco Nexus
Virtual Port Channel (VPC) is a feature in Cisco Nexus switches that allows you to create a logical link between two switches. This link enables you to have redundancy and load balancing in your network, as well as increase overall resiliency.
Configuring VPC on Cisco Nexus switches is a straightforward process, but it requires attention to detail to ensure a successful setup. In this article, we will guide you through the steps to configure VPC on your Cisco Nexus switch.
Prerequisites
- Access to Cisco Nexus switch
- Console or SSH access to the switch
- Basic knowledge of Cisco Nexus CLI
- Understanding of VPC concepts
Step 1: Configure VPC Domain
The first step in configuring VPC on Cisco Nexus is to define a VPC domain. This domain acts as a unique identifier for the VPC peer switches. To configure the VPC domain, use the following command:
switch# conf t
switch(config)# vpc domain 10
switch(config-vpc-domain)# peer-keepalive destination 192.168.1.2
switch(config-vpc-domain)# exit
Step 2: Configure VPC Peer-Link
Next, you will need to configure the VPC peer-link, which is the link that connects the VPC peer switches. Make sure to specify the interface, speed, and VLAN settings for the peer-link. Here is an example configuration:
switch(config)# interface ethernet 1/1
switch(config-if)# switchport mode trunk
switch(config-if)# channel-group 1 mode active
switch(config-if)# exit
Step 3: Configure VPC Member Ports
After configuring the peer-link, you can now configure the VPC member ports. These are the ports on the switches that will be part of the VPC setup. Here is an example configuration for a member port:
switch(config)# interface ethernet 1/2
switch(config-if)# switchport mode trunk
switch(config-if)# channel-group 1 mode active
switch(config-if)# exit
Step 4: Verify VPC Configuration
Once you have completed the VPC configuration, it is important to verify that it has been set up correctly. Use the following command to check the VPC status and configuration:
switch# show vpc
If the VPC configuration is successful, you should see output that confirms the VPC status and configuration details.
Conclusion
Configuring VPC on Cisco Nexus switches is essential for creating a resilient and high-performing network. By following the steps outlined in this article, you can successfully set up VPC on your Cisco Nexus switch and enjoy the benefits of improved redundancy and load balancing.
Remember to test your VPC setup thoroughly and monitor its performance to ensure that your network remains stable and efficient.
