Setup Guide

5 Congure the backup link between the VLT peer units (shown in the following example).
6 Congure the peer 2 management ip/ interface ip for which connectivity is present in VLT peer 1.
EXEC Privilege mode
show running-config vlt
7 Congure the peer 1 management ip/ interface ip for which connectivity is present in VLT peer 1.
EXEC mode or EXEC Privilege mode
show interfaces interface
8 Congure the VLT links between VLT peer 1 and VLT peer 2 to the top of rack unit (shown in the following example).
9 Congure 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 Congure 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, congure 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

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 EMC 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 1/4-1/7
Dell-4(conf)#interface port-channel 1
Dell-4(conf-if-po-1)#channel-member TenGigabitEthernet 1/4-1/7
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.
