9. Configure the static LAG/LACP between ports connected from VLT peer 1 and VLT peer 2 to the top of rack unit. EXEC Privilege mode show running-config entity 10. Configure the VLT peer link port channel id in VLT peer 1 and VLT peer 2. EXEC mode or EXEC Privilege mode show interfaces interface 11. In the top of rack unit, configure LACP in the physical ports. EXEC Privilege mode show running-config entity 12. Verify that VLT is running. EXEC mode show vlt brief or show vlt detail 13. Verify that the VLT LAG is running in both VLT peer units. EXEC mode or EXEC Privilege mode show interfaces interface Example of Configuring VLT In the following sample VLT configuration steps, VLT peer 1 is Dell-2, VLT peer 2 is Dell-4, and the ToR is S60-1. NOTE: If you use a third-party ToR unit, Dell Networking recommends using static LAGs with VLT peers to avoid potential problems if you reboot the VLT peers. Configure the VLT domain with the same ID in VLT peer 1 and VLT peer 2. Dell-2(conf)#vlt domain 5 Dell-2(conf-vlt-domain)# Dell-4(conf)#vlt domain 5 Dell-4(conf-vlt-domain)# Configure the VLTi between VLT peer 1 and VLT peer 2. 1. You can configure the LACP/static LAG between the peer units (not shown). 2. Configure the peer-link port-channel in the VLT domains of each peer unit. Dell-2(conf)#interface port-channel 1 Dell-2(conf-if-po-1)#channel-member TenGigabitEthernet 0/4-7 Dell-4(conf)#interface port-channel 1 Dell-4(conf-if-po-1)#channel-member TenGigabitEthernet 0/4-7 Configure the backup link between the VLT peer units. 1. Configure the peer 2 management ip/ interface ip for which connectivity is present in VLT peer 1. 1088 Virtual Link Trunking (VLT)
