atmVplEntry

An entry in the VPL table.  This entry is
used to model a bi-directional VPL.
To create a VPL at an ATM interface,
either of the following procedures are used:
            
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 service category
  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.
  If the transmit and receive service categories
  are inconsistent, the agent should 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 service category
  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
            
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.
