                      either of the following procedures are used:

Top      Up      ToC       Page 34 
                      Negotiated VPL establishment

                    (1) The management application creates
                        a VPL entry in the atmVplTable
                        by setting atmVplRowStatus to createAndWait(5).
                        This may fail for the following reasons:
                        - The selected VPI value is unavailable,
                        - The selected VPI value is in use.
                        Otherwise, the agent creates a row and
                        reserves the VPI value on that port.

                    (2) The manager selects an existing row(s) in the
                        atmTrafficDescrParamTable,
                        thereby, selecting a set of self-consistent
                        ATM traffic parameters and the QoS Class
                        for receive and transmit directions of the VPL.

                   (2a) If no suitable row(s) in the
                        atmTrafficDescrParamTable exists,
                        the manager must create a new row(s)
                        in that table.

                   (2b) The manager characterizes the VPL's traffic
                        parameters through setting the
                        atmVplReceiveTrafficDescrIndex and the
                        atmVplTransmitTrafficDescrIndex values
                        in the VPL table, which point to the rows
                        containing desired ATM traffic parameter values
                        in the atmTrafficDescrParamTable.  The agent
                        will check the availability of resources and
                        may refuse the request.

                    (3) The manager activates the VPL by setting the
                        the atmVplRowStatus to active(1).
                        If this set is successful, the agent has
                        reserved the resources to satisfy the requested
                        traffic parameter values and the QoS Class
                        for that VPL.
                    (4) If the VPL terminates a VPC in the ATM host
                        or switch, the manager turns on the
                        atmVplAdminStatus to up(1) to turn the VPL
                        traffic flow on.  Otherwise, the
                        atmVpCrossConnectTable  must be used
                        to cross-connect the VPL to another VPL(s)
                        in an ATM switch or network.

                      One-Shot VPL Establishment

Top      Up      ToC       Page 35 
                      A VPL may also be established in one step by a
                      set-request with all necessary VPL parameter
                      values and atmVplRowStatus set to createAndGo(4).

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

                      VPL Retirement

                      A VPL is released by setting atmVplRowStatus to
                      destroy(6), and the agent may release all
                      associated resources."

                      either of the following procedures are used:

                      Negotiated VCL establishment

                    (1) The management application creates
                        a VCL entry in the atmVclTable

Top      Up      ToC       Page 39 
                        by setting atmVclRowStatus to createAndWait(5).
                        This may fail for the following reasons:
                        - The selected VPI/VCI values are unavailable,
                        - The selected VPI/VCI values are in use.
                        Otherwise, the agent creates a row and
                        reserves the VPI/VCI values on that port.

                    (2) The manager selects an existing row(s) in the
                        atmTrafficDescrParamTable,
                        thereby, selecting a set of self-consistent
                        ATM traffic parameters and the QoS Class
                        for receive and transmit directions of the VCL.

                   (2a) If no suitable row(s) in the
                        atmTrafficDescrParamTable exists,
                        the manager must create a new row(s)
                        in that table.

                   (2b) The manager characterizes the VCL's traffic
                        parameters through setting the
                        atmVclReceiveTrafficDescrIndex and the
                        atmVclTransmitTrafficDescrIndex values
                        in the VCL table, which point to the rows
                        containing desired ATM traffic parameter values
                        in the atmTrafficDescrParamTable.  The agent
                        will check the availability of resources and
                        may refuse the request.

                    (3) The manager activates the VCL by setting the
                        the atmVclRowStatus to active(1).
                        If this set is successful, the agent has
                        reserved the resources to satisfy the requested
                        traffic parameter values and the QoS Class
                        for that VCL.
                    (4) If the VCL terminates a VCC in the ATM host
                        or switch, the manager turns on the
                        atmVclAdminStatus to up(1) to turn the VCL
                        traffic flow on.  Otherwise, the
                        atmVcCrossConnectTable  must be used
                        to cross-connect the VCL to another VCL(s)
                        in an ATM switch or network.

                     One-Shot VCL Establishment

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

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

                     VCL Retirement

                     A VCL is released by setting atmVclRowStatus to
                     destroy(6), and the agent may release all
                     associated resources."
