Please bare with me as I am new to the Cisco Flex Stack technology. Our organization have Two Cisco 2960x swithes stack with FlexStack Plus technology. Each switch has an uplink cable (Total two) connected to the upstream core router running HSRP protocol. We are going to have a resilience test where our upstream router administrator will disable one of the primary uplink cable to see if the Cisco 2960x can switch over to the secondary switch can take over task for service resilience. Then upstream router administrator will enable back the primary uplink to see if the traffic can failback to the primary/master switch.
Our question is what is the health check procedure (or IOS command) to check if the traffic is actully fail over to the secondary switch and what command to check if the traffic is indeed failback to the original one ? Kindly let us know if any health check diagnostic command might help during this exercise.
Thank you so much for your technical advice in advance.
