VLT Sample Configuration
To review a sample VLT configuration setup, study these steps.
1 Configure the VLT domain with the same ID in VLT peer 1 and VLT peer 2.
VLT DOMAIN mode
vlt domain domain id
2 Configure the VLTi between VLT peer 1 and VLT peer 2.
3 You can configure LACP/static LAG 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. 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
channel-member
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.
