Example of Conguring VLT
In the following sample VLT conguration 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.
Congure 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)#
Congure the VLTi between VLT peer 1 and VLT peer 2.
1 You can congure the LACP/static LAG between the peer units (not shown).
2 Congure 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
Congure the backup link between the VLT peer units.
1 Congure the peer 2 management ip/ interface ip for which connectivity is present in VLT peer 1.
2 Congure the peer 1 management ip/ interface ip for which connectivity is present in VLT peer 2.

Congure the VLT links between VLT peer 1 and VLT peer 2 to the Top of Rack unit. In the following example, port Te 0/40 in VLT peer 1 is
connected to Te 0/48 of TOR and port Te 0/18 in VLT peer 2 is connected to Te 0/50 of TOR.
1 Congure the static LAG/LACP between the ports connected from VLT peer 1 and VLT peer 2 to the Top of Rack unit.
2 Congure the VLT peer link port channel id in VLT peer 1 and VLT peer 2.
3 In the Top of Rack unit, congure 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 congured in VLT peer 2).
