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

Configure the VLT links between VLT peer 1 and VLT peer 2 to the Top of Rack unit. In the following example, port Te 1/4 in VLT peer
1 is connected to Te 1/8 of TOR and port Te 1/18 in VLT peer 2 is connected to Te 1/30 of TOR.
1. Configure the static LAG/LACP between the ports connected from VLT peer 1 and VLT peer 2 to the Top of Rack unit.
2. Configure the VLT peer link port channel id in VLT peer 1 and VLT peer 2.
3. In the Top of Rack unit, configure 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 configured in VLT peer 2).
