To verify the configuration of a VLT domain, use any of the show commands described in
Verifying a VLT
Configuration.
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.
