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). SUMMARY STEPS 1. configure terminal 2. vpc domain domain-id 3. role priority priority 4. exit 5. (Optional) show vpc role 6.
