This example uses interfaces 1/1/49-1/1/52 for the VLTi between the two leaf switches. Remove each interface from Layer 2 mode with the no switchport command. Enable jumbo frames on the VLANs with the mtu 9216 command.
Create the VLT domain. The backup destination is the OOB management IP address of the VLT peer switch. Configure the interfaces used as the VLTi with the discovery-interface command. Specify a virtual MAC address that the switches will share. Enable peer routing.
Note: The manual configuration of the VLT MAC address minimizes the time required to synchronize the default MAC address of the VLT domain on both peer devices when one peer switch reboots.
