How can i create an iRule for one VIP with multiple service ports.

It's possible but you need to set VIP destination port to 0. And write irule to allow defined port and block rest of the service.

Below irule might help...

    when CLIENT_ACCEPTED {
       if { [TCP::local_port] == 5540 } {
        pool test_PROD_pool1
        } elseif { [TCP::local_port] == 5580 } {
        pool test_PROD_pool2
        } else {
            reject
    }
}

Cheers...
