Wide open pool member - I-Rule to monitor node

Hello , I have a request to create 100 VS which uses the same VIP but 100 different TCP ports and same on the back end two node with 100 TCP ports. I am thinking to use a wide open VS and pool, and add an Irule to limit the access by inspecting the Client accepted ports. The help I need is how to monitor the back end pool member if one node is down. Please can I get some advice

    Assuming each port is for a unique application, you would have to create 100 Pools with unique monitors per pool. You can use a single catch-all VS that directs traffic to any of the 100 configured pools based on incoming port request. You can use a datagroup or switch statement within iRule. I would recommend datagroup for a cleaner iRule.
