Create vPC Logical Interfaces with Config Mirroring

Build vPC port-channels with automatic configuration mirroring—ensuring consistency across both vPC peers.

Logical Interfaces

Much like the access interface you modified, this section focuses on creating a brand new Logical Interface—a vPC interface from your Site1-L1 and Site1-L2 vPC pairs.

Config Mirroring

ND's config mirroring feature automatically replicates port-channel settings to both vPC peers, preventing common misconfiguration issues.

Lab Environment Note

Since these switches reside inside of a CML environment, the vPC interface will not actually come up. But this showcases the simplicity of ND when configuring vPC. These steps can be repeated or further automated for any number of vPC interfaces.

Step 1 - Clear Previous Filter

Clear the filter used in the previous section by:

  1. clicking the small on your filter parameter

Step 2 - Launch Create Interface Wizard

With the filter cleared in preparation for applying another one later, it's time for you to create an interface:

  1. Click Actions on the far right
  2. Click Create Interface in the dropdown menu

Step 3 - Populate Create Interface Wizard for a vPC Interface

The Create Interface wizard supports creating many different types of interfaces and is dynamic in what is displayed to you based on the interface type selected.

  1. Set the Type to virtual Port-Channel (vPC)
  2. Select Trunk
  3. The vPC pair should already be set to Site1-L1--Site1-L2
  4. Leave the vPC ID set to 1
  5. Click Enable Config Mirrowing
  6. Locate the Peer-1 Member Interfaces and set the interface to eth1/6
  7. Click Save



  8. Then click Deploy

Step 4 - Deploy Interface Configuration

After clicking Deploy, Nexus Dashboard launches the Deploy interfaces configuration wizard. Review the pending configuration as desired. Once done:

  1. Click Deploy Config in the bottom right

    2. You will see the intended vPC interface configuration start being deployed for Port-Channel 1 (that is a vPC) with the Ethernet1/6 interface on Site1-L1 and Site2-L1 as members.

Step 6 - Review vPC is Created

    Back at the main Interfaces overview, locate the vPC1 interface for Site1-L1 and Site1-L2 by using the filter option at the top. Again, for this lab, the vPC interface will remain down, but show consistent between Site1-L1 and Site1-L2. This process demonstrates how you would create a vPC interface.
  1. In the filter box type Interface == vPC1
  2. Review the vPC1 interface you created
  3. Clear the filter box by clicking the small on your filter parameter
