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 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 highlighted vlt-peer-lag port-channel 2 indicates that port-channel 2 is the port-
channel id configured in VLT peer 2).
