很不错java的SNMP应用例子

          [For example, for setting up
          a point-to-point VP cross-connect, the
          ATM traffic parameters in the receive direction
          of a VPL at the low end of the cross-connect
          must equal to the traffic parameters in the
          transmit direction of the other VPL at the
          high end of the cross-connect,
          otherwise, the row creation fails.]
          The agent also checks for internal errors
          in building the cross-connect.

          The atmVpCrossConnectIndex values in the
          corresponding atmVplTable rows are filled
          in by the agent at this point.

     (2b) The manager promotes the row in the
          atmVpCrossConnectTable by setting
          atmVpCrossConnectRowStatus to active(1).  If
          this set is successful, the agent has reserved
          the resources specified by the ATM traffic
          parameter and Service category values
          for each direction of the VP cross-connect
          in an ATM switch or network.

      (3) The manager sets the
          atmVpCrossConnectAdminStatus to up(1) in all
          rows of this VP cross-connect to turn the
          traffic flow on.


       One-Shot VP Cross-Connect Establishment

       A VP cross-connect may also be established in
       one step by a set-request with all necessary
       parameter values and atmVpCrossConnectRowStatus
       set to createAndGo(4).

       In contrast to the negotiated VP cross-connect
       establishment which allows for detailed error
       checking (i.e., set errors are explicitly linked
       to particular resource acquisition failures),
       the one-shot VP cross-connect establishment
       performs the setup on one operation but does not
       have the advantage of step-wise error checking.

       VP Cross-Connect Retirement

       A VP cross-connect identified by a particular
       value of atmVpCrossConnectIndex is released by:

      (1) Setting atmVpCrossConnectRowStatus of all
          rows identified by this value of
          atmVpCrossConnectIndex to destroy(6).
          The agent may release all
          associated resources, and the
          atmVpCrossConnectIndex values in the
          corresponding atmVplTable row are removed.
          Note that a situation when only a subset of
          the associated rows are deleted corresponds
          to a VP topology change.

      (2) After deletion of the appropriate
          atmVpCrossConnectEntries, the manager may
          set atmVplRowStatus to destroy(6) the
          associated VPLs.  The agent releases
          the resources and removes the associated
          rows in the atmVplTable.

       VP Cross-connect Reconfiguration

       At the discretion of the agent, a VP
       cross-connect may be reconfigured by
       adding and/or deleting leafs to/from
       the VP topology as per the VP cross-connect
       establishment/retirement procedures.
       Reconfiguration of traffic/service category parameter
       values requires release of the VP cross-connect
       before those parameter values may by changed
       for individual VPLs."

      "An entry in the ATM VC Cross Connect table.
       This entry is used to model a bi-directional ATM
       VC cross-connect cross-connecting two end points.

       Step-wise Procedures to set up a VC Cross-connect
       Once the entries in the atmVclTable are created,
       the following procedures are used
       to cross-connect the VCLs together to
       form a VCC segment.

      (1) The manager obtains a unique
          atmVcCrossConnectIndex by reading the
          atmVcCrossConnectIndexNext object.

      (2) Next, the manager creates a set of one
          or more rows in the ATM VC Cross Connect
          Table, one for each cross-connection between
          two VCLs.  Each row is indexed by the ATM
          interface port numbers and VPI/VCI values of
          the two ends of that cross-connection.
          This set of rows specifies the topology of the
          VCC cross-connect and is identified by a single
          value of atmVcCrossConnectIndex.

       Negotiated VC Cross-Connect Establishment

     (2a) The manager creates a row in this table by
          setting atmVcCrossConnectRowStatus to
          createAndWait(5).  The agent checks the
          requested topology and the mutual sanity of
          the ATM traffic parameters and
          service categories, i.e., the row creation
          fails if:
          - the requested topology is incompatible with
            associated values of atmVclCastType,
          - the requested topology is not supported
            by the agent,
          - the traffic/service category parameter values
            associated with the requested row are
            incompatible with those of already existing
            rows for this VC cross-connect.
          [For example, for setting up
          a point-to-point VC cross-connect, the
          ATM traffic parameters in the receive direction
          of a VCL at the low end of the cross-connect
          must equal to the traffic parameters in the
          transmit direction of the other VCL at the
          high end of the cross-connect,
          otherwise, the row creation fails.]
          The agent also checks for internal errors
          in building the cross-connect.

          The atmVcCrossConnectIndex values in the
          corresponding atmVclTable rows are filled
          in by the agent at this point.

     (2b) The manager promotes the row in the
          atmVcCrossConnectTable by setting
          atmVcCrossConnectRowStatus to active(1).  If
          this set is successful, the agent has reserved
          the resources specified by the ATM traffic
          parameter and Service category values
          for each direction of the VC cross-connect
          in an ATM switch or network.

      (3) The manager sets the
          atmVcCrossConnectAdminStatus to up(1)
          in all rows of this VC cross-connect to
          turn the traffic flow on.


       One-Shot VC Cross-Connect Establishment

       A VC cross-connect may also be established in
       one step by a set-request with all necessary
       parameter values and atmVcCrossConnectRowStatus
       set to createAndGo(4).

       In contrast to the negotiated VC cross-connect
