Disable VS when Assosiated Pool is down

Once you add a TCP profile to a virtual server, BIG-IP will answer SYNs with a SYN ACK regardless of the state of its resources. If you wanted to disable a virtual server if the pool is down, you'd need to use iControl. Check the iControl forum for more info on that.

Else, if you want to reset the established TCP connection, you could use a rule like this:

 this event is triggered when a TCP handshake is complete with the client
when CLIENT_ACCEPTED {
    check if there are no active members in the default pool of the virtual server
   if {[active_members [LB::server pool]] < 1}{
       send a TCP reset to the client
      reject
   }
}
