ltm vip port list

The status of the virtual server typically relies on the status of the default pool and health check monitor that is bound to it. The virtual server will only show as offline if *ALL* pool members fail their load balancer health checks. This is true for virtual servers that use traffic-matching-criteria (such as port lists and address-lists). You can't check the status of the virtual server that is using a port list by a port-by-port basis; the virtual server statistics are aggregated for all ports.
