Verfication is a string that must match a verification code at
    the receiving system in order to trigger the bootstrap mechanism.
    The default verification is '0000000000000000'H.  Verification is
    an optional argument, but Address information is required, either
    from the command line or from the MOP Client database.

    boot  [node node-id] mop circuit circuit-name -
          address lan-address, verification hex-string

    Or, to override any default Verification information for this
    Client in the MOP Client database:

    boot  [node node-id] mop circuit circuit-name -
          client client-name, verification hex-string

    Examples:

    boot mop circuit fddi-1 address 08-00-2b-00-33-44, -
          verification %x0000000000000011

    boot mop circuit csmacd-1 client lamchp, -
          verification %x0000000000000011
