    Hi All,

    yes, Alex, it's pingable from the switch,

    Switch>ping 192.168.168.12

    Type escape sequence to abort.
    Sending 5, 100-byte ICMP Echos to 192.168.168.12, timeout is 2 seconds:
    !!!!!
    Success rate is 100 percent (5/5), round-trip min/avg/max = 1/202/1006 ms
     Cheers.

    Mark Sargent.
