interface port-channel port-channel id
NOTE: To benefit from the protocol negotiations, Dell Networking recommends configuring VLTs used as facing hosts/
switches with LACP. Ensure both peers use the same port channel ID.
4 Configure the peer-link port-channel in the VLT domains of each peer unit.
INTERFACE PORTCHANNEL mode

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