Manually Configuring the vPC Peer Device Role

By default, the Cisco NX-OS software elects a primary and secondary vPC peer device after you
configure the vPC domain and both sides of the vPC peer link. However, you may want to elect a specific
vPC peer device as the primary device for the vPC. Then, you would manually configure the role value
for the vPC peer device that you want as the primary device to be lower than the other vPC peer device.
vPC does not support role preemption. If the primary vPC peer device fails, the secondary vPC peer
device takes over to become operationally the vPC primary device. However, the original operational
roles are not restored if the formerly primary vPC comes up again.
BEFORE YOU BEGIN
Ensure that you have enabled the vPC feature.
Ensure that you are in the correct VDC (or use the switchto vdc command).
