"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."

DESCRIPTION
"An entry in the ATM VP Cross Connect table.
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
service categories, i.e., the row creation
fails if:
- the requested topology is incompatible with
associated values of atmVplCastType,
- 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 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 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."
