7.6 Configure VLT The QSFP28-DD ports on the S5248F-ON are used for the VLTi between the two leaf switches as shown in Figure 5. The two physical QSFP28-DD ports provide four 100GbE interfaces, 1/1/49-1/1/52. Configure the VLTi interfaces as follows: 1. Provide an interface description. 2. Remove each interface from Layer 2 mode with the no switchport command. 3. Set the MTU to its maximum size, 9216 bytes. Configure the VLT domain as follows: 1. Create the VLT domain with the vlt-domain domain_id_number command. Use any number from 1-255 as the domain ID. Use the same ID number on both VLT peers. 2. Set the backup destination IP address. The backup destination is the OOB management IP address of the VLT peer switch. 3. Configure the interfaces used as the VLTi with the discovery-interface command. 4. Enable peer routing. Note: For more information on VLT, see the OS10 Enterprise Edition User Guide Release 10.4.2.0. 5. When the configuration is complete, exit configuration mode and save the configuration with the end and write memory commands.
