1  –  mop

1.1  –  circuit 

    Initiates an XID exchange between the system specified by node-
    id and the system specified by the arguments or a client.

    query  [node node-id] mop circuit circuit-name -
            address lan-address [,sap octet]

    The Address information is required.  If Address is not specified
    in the command, then a Client must be specified which can supply
    the address information.

    query [node node-id] mop circuit circuit-name -
            client client-name [,sap octet]

    SAP is an optional argument for the query mop circuit command.
    The optional SAP argument specifies the Service Access Point on
    the target system to which the XID message is to be sent.  SAP is
    an octet (00-FF).  The default SAP is 00.

    The query requester function must be enabled on the MOP Circuit
    to perform the query operation.  You may enable this function
    using:

    enable mop circuit circuit-name function {query requester}

    Examples:

    query mop circuit csmacd-1 address 08-00-2b-45-77-ED

    query mop circuit csmacd-1 -
        client lamchp ! Client lamchp has the Address.

1.1.1  –  Exception Messages 

 o  data link error

    An error was reported by the Data Link layer.  Ascertain that
    the query requester function is enabled on the MOP circuit.

 o  unrecognized client

    There is no client with the specified identification.

 o  unrecognized circuit

    There is no circuit with the specified identification.

 o  timeout

    Operation has timed out on the loop command.

 o  entity class not supported (OpenVMS)

    MOP is not registered with EMAA.  The NET$MOP process is
    probably not started.  For instructions on how to restart the
    MOP process, refer to HELP NETWORK_MANAGEMENT MOP.

1.2  –  client 

    Initiates an XID exchange between the system specified by node-id
    and the client.

    query  [node node-id] mop client client-name [,sap octet]

    The Address and Circuit information is required.  If the Client
    cannot provide that information, then it must be supplied in the
    command.

    query [node node-id] mop client client-name -
          address lan-address, -
          circuit circuit-name [,sap octet]

    The optional SAP argument specifies the Service Access Point on
    the target system to which the XID message is to be sent.  SAP is
    an octet (00-FF).  The default SAP is 00.

    The query requester function must be enabled on the MOP Circuit
    to perform the query operation.  You may enable this function
    using:

    enable mop circuit circuit-name function {query requester}

    Examples:

    query mop client lamchp -       ! Client provides the Circuit.
          address 08-00-2b-34-09-FF

    query mop client lamchp -       ! Client provides the Address.
