Dell-4(conf)#vlt domain 5
Dell-4(conf-vlt-domain)#
Congure the VLTi between VLT peer 1 and VLT peer 2.
1. You can congure the LACP/static LAG between the peer units (not shown).
2. Congure the peer-link port-channel in the VLT domains of each peer unit.

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

Congure the VLT links between VLT peer 1 and VLT peer 2 to the Top of Rack unit. In the following example, port Gi 1/4 in VLT peer
1 is connected to Gi 1/8 of TOR and port Gi 1/18 in VLT peer 2 is connected to Gi 1/30 of TOR.
1. Congure the static LAG/LACP between the ports connected from VLT peer 1 and VLT peer 2 to the Top of Rack unit.
2. Congure the VLT peer link port channel id in VLT peer 1 and VLT peer 2.
3. In the Top of Rack unit, congure LACP in the physical ports (shown for VLT peer 1 only. Repeat steps for VLT peer 2. The bold
vlt-peer-lag port-channel 2 indicates that port-channel 2 is the port-channel id congured in VLT peer 2).
