    Hi Meshal,

    what about creating two pools? Pools are using the same nodes but listen on the 2 different ports. 

    ltm pool pool_port_8081 {
    members {
        10.131.131.101:8081 {
            address 10.131.131.101
        }
        10.131.131.102:8081 {
            address 10.131.131.102
        }
    }
    monitor http_head_f5
}
ltm pool pool_port_8082 {
    members {
        10.131.131.101:8082 {
            address 10.131.131.101
        }
        10.131.131.102:8082 {
            address 10.131.131.102
        }
    }
    monitor http_head_f5
}

    An iRule may solve the problem by checking the availability of pool_port_8081 first and forwards to pool_port_8082 in case there are no members available on the "primary" pool_port_8081. 

    when CLIENT_ACCEPTED {
     two pools configured (same nodes using different ports)
    if { [active_members pool_port_8081] > 0 } {
        pool pool_port_8081
    } else {
        pool pool_port_8082
    }
}

    Thanks, Stephan
