there are two switches with vPC. SW1 - primary, SW2 - secondary. We use the "delay restore 360" option. Peer link is a separate Po1. Keepalive link is a separate Po2. Po 101 and Po 102 are vPC. We had a need before working shutdown Po 101 and Po102. After that, on the secondary switch it was necessary to issue the no port-channel load-balance hash-modulo command. Therefore, ALL Po down and then up. SW2 became operation primary, and SW1 operation secondary. As a result, Po 101 and 102 on SW1 were able to down 360 seconds.
