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 1/1/4/1-1/1/4/4
Dell-4(conf)#interface port-channel 1
Dell-4(conf-if-po-1)#channel-member TenGigabitEthernet 1/1/4/1-1/1/4/4
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.
2 Configure the peer 1 management ip/ interface ip for which connectivity is present in VLT peer 2.
Configure the VLT links between VLT peer 1 and VLT peer 2 to the Top of Rack unit. In the following example, port Te 1/1/4/1 in VLT peer 1
is connected to Te 1/1/8/1 of ToR and port Te 1/1/5/1 in VLT peer 2 is connected to Te 1/1/3/1 of ToR.
1 Configure the static LAG/LACP between the ports connected from VLT peer 1 and VLT peer 2 to the Top of Rack unit.
2 Configure the VLT peer link port channel id in VLT peer 1 and VLT peer 2.
3 In the Top of Rack unit, configure LACP in the physical ports (shown for VLT peer 1 only. Repeat steps for VLT peer 2. The bold vlt-
peer-lag port-channel 2 indicates that port-channel 2 is the port-channel id configured in VLT peer 2).
