(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.

This entry is used to model a bi-directional ATM VP cross-connect which cross-connects two VPLs. Step-wise Procedures to set up a VP Cross-connect Once the entries in the atmVplTable are created, the following procedures are used to cross-connect the VPLs together. (1) The manager obtains a unique atmVpCrossConnectIndex by reading the atmVpCrossConnectIndexNext object. (2) Next, the manager creates a set of one or more rows in the ATM VP Cross Connect Table, one for each cross-connection between two VPLs. Each row is indexed by the ATM interface port numbers and VPI values of the two ends of that cross-connection. This set of rows specifies the topology of the VPC cross-connect and is identified by a single value of atmVpCrossConnectIndex. Negotiated VP Cross-Connect Establishment (2a) The manager creates a row in this table by setting atmVpCrossConnectRowStatus to createAndWait(5). The agent checks the requested topology and the mutual sanity of the ATM traffic parameters and QoS Classes, i.e., the row creation fails if: - the requested topology is not supported by the agent, - the traffic/QoS parameter values associated with the requested row are incompatible with those of already existing rows for this VP cross-connect. [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 QoS Class 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/QoS parameter values requires release of the VP cross-connect before those parameter values may by changed for individual VPLs."
