Configure the VLT links between VLT peer 1 and VLT peer 2 to the Top of Rack unit. In the following
example, port Te 0/40 in VLT peer 1 is connected to Te 0/48 of TOR and port Te 0/18 in VLT peer 2 is
connected to Te 0/50 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).
