MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"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 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
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."

Negotiated VCL establishment
(1) The management application creates
a VCL entry in the atmVclTable
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."
