Example of Conguring VLT
In the following sample VLT conguration 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.
Congure 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)#
Congure the VLTi between VLT peer 1 and VLT peer 2.
1 You can congure the LACP/static LAG between the peer units (not shown).
2 Congure 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
Congure the backup link between the VLT peer units.
1 Congure the peer 2 management ip/ interface ip for which connectivity is present in VLT peer 1.
2 Congure the peer 1 management ip/ interface ip for which connectivity is present in VLT peer 2.
Congure 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 Congure the static LAG/LACP between the ports connected from VLT peer 1 and VLT peer 2 to the Top of Rack unit.
2 Congure the VLT peer link port channel id in VLT peer 1 and VLT peer 2.
3 In the Top of Rack unit, congure 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 congured in VLT peer 2).
