NOTE: To benet from the protocol negotiations, Dell Networking recommends conguring VLTs used as facing hosts/
switches with LACP. Both peers must use the same port channel ID.
3 Congure the peer-link port-channel in the VLT domains of each peer unit.

4 Congure the backup link between the VLT peer units. Congure the peer 2 management ip/ interface ip for which connectivity is
present in VLT peer 1.

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

In the following sample VLT conguration steps, VLT peer 1 is FN IOM-2, VLT peer 2 is FN IOM-4, and the ToR is FN IOM-1.
NOTE
: If you use a third-party ToR unit, Dell Networking recommends using static LAGs with VLT peers to avoid potential
problems if the VLT peers are rebooted.
Congure the VLT domain with the same ID in VLT peer 1 and VLT peer 2

Congure the VLTi between VLT peer 1 and VLT peer 2
1 LACP/Static LAG can be congured between the peer units (not shown).
