Example of Configuring VLT
In the following sample VLT configuration steps, VLT peer 1 is , VLT peer 2 is , 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.
s4810-2(conf)#vlt domain 5
s4810-2(conf-vlt-domain)#
s4810-4(conf)#vlt domain 5
s4810-4(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.
s4810-2(conf)#interface port-channel 1
s4810-2(conf-if-po-1)#channel-member TenGigabitEthernet 1/4-7
s4810-4(conf)#interface port-channel 1
s4810-4(conf-if-po-1)#channel-member TenGigabitEthernet 1/4-7
