Connecting a VLT Domain
To connect a VLT domain to an attached access device, use the following commands.
For more information, refer to Verifying a VLT Configuration.
1 Configure the VLT domain with the same ID in VLT peer 1 and VLT peer 2.
VLT DOMAIN
vlt domain domain id
2 Configure the VLTi between VLT peer 1 and VLT peer 2. LACP/Static LAG can be configured between
the peer units (not shown).
CONFIGURATION mode
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. Both peers must use the same port channel ID.
3 Configure the peer-link port-channel in the VLT domains of each peer unit.
INTERFACE PORTCHANNEL mode
channel-member
4 Configure the backup link between the VLT peer units. Configure the peer 2 management ip/ interface
ip for which connectivity is present in VLT peer 1.
EXEC Privilege mode

5 Configure the peer 1 management ip/ interface ip for which connectivity is present in VLT peer 1.
EXEC mode or EXEC Privilege mode

6 Configure the VLT links between VLT peer 1 and VLT peer 2 to the top of rack unit. Configure the
static LAG/LACP between ports connected from VLT peer 1 and VLT peer 2 to the top of rack unit.
