Congure 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 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).
