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.

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

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.
