FRNETSERV-MIB Table View

The Frame Relay Logical Port Information table is
an interface-specific addendum to the generic
ifTable of the Interface MIB.

The Frame Relay Management VC Signaling
Parameters and Errors table.

The Frame Relay PVC End-Point table.  This table
is used to model a PVC end-point.  This table
contains the traffic parameters and statistics for
a PVC end-point.
          
This table is used to identify the traffic
parameters for a bi-directional PVC segment end-
          
point, and it also provides statistics for a PVC
segment end-point.
          
A PVC segment end-point is identified by a UNI/NNI
logical port index value and DLCI index value.
          
If the frame relay service provider allows the
frame relay CNM subscriber to create, modify or
delete PVCs using SNMP, then this table is used to
identify and reserve the requested traffic
parameters of each PVC segment end-point.  The
Connection table is used to 'connect' the end-
points together.  Not all implementations will
support the capability of
creating/modifying/deleting PVCs using SNMP as a
feature of frame relay CNM service.
          
Uni-directional PVCs are modeled with zero valued
traffic parameters in one of the directions (In or
 Out direction) in this table.
          
To create a PVC, the following procedures shall be
followed:
          
1)  Create the entries for the PVC segment
    endpoints in the frPVCEndptTable by specifying
    the traffic parameters for the bi-directional
    PVC segment endpoints. As shown in figure 2, a
    point-to-point PVC has two endpoints, thus two
    entries in this table.  Uni-directional PVCs
    are modeled with zero valued traffic
    parameters in one direction; all the `In'
    direction parameters for one frame relay PVC
    End-point or all the `Out' direction
    parameters for the other frame relay PVC
    Endpoint.

2)  Go to the Frame Relay Connection Group.

The Frame Relay PVC Connect Table is used to
model the bi-directional PVC segment flows
including:  point-to-point PVCs, point-to-
multipoint PVCs, and multipoint-to-multipoint
PVCs.
          
This table has read-create access and is used to
associate PVC end-points together as belonging to
one connection.  The frPVCConnectIndex is used to
associate all the bi-directional flows.  Not all
implementations will support the capability of
creating/modifying/deleting PVCs using SNMP as a
feature of frame relay CNM service.
          
Once the entries in the frPVCEndptTable are
created, the following step are used to associate
the PVC end-points as belonging to one PVC
connection:
          
1)  Obtain a unique frPVCConnectIndex
    using the frPVCConnectIndexValue object.
          
2)  Connect the PVC segment endpoints together
    with the applicable frPVCConnectIndex value
    obtained via  frPVCConnectIndexValue.  The
    entries in this table are created by using
    the frPVCConnectRowStatus object.
          
3)  The agent will provide the value of the
    corresponding instances of
    frPVCEndptConnectIdentifier with the
    frPVCConnectIndex value.
          
4)  Set frPVCConnectAdminStatus to `active(1)' in
          
    all rows for this PVC segment to turn the
    PVC on.
          
For example, the Frame Relay PVC Connection Group
models a bi-directional, point-to-point PVC
segment as one entry in this table.

   _____| >> from low to high PVC flow  >> |_____
        | << from high to low PVC flow  << |
        |__________________________________|
          
The terms low and high are chosen to represent
numerical ordering of a PVC segment's endpoints
for representation in this table.  That is, the
endpoint with the lower value of ifIndex is termed
'low', while the opposite endpoint of the segment
is termed 'high'.  This terminology is to provide
directional information; for example the
frPVCConnectL2hOperStatus and
frPVCConnectH2lOperStatus as illustrated above.
          
If the Frame Relay Connection table is used to
model a unidirectional PVC, then one direction
(either from low to high or from high to low) has
 its Operational Status equal to down.
          
 A PVC segment is a portion of a PVC that traverses
one Frame Relay Network, and a PVC segment is
identified by its two end-points (UNI/NNI logical
port index value and DLCI index value) through one
Frame Relay Network.

is used to perform accounting on a PVC segment
end-point basis.

The Frame Relay Accounting Logical Port table.
This table is used to perform accounting on a
UNI/NNI Logical Port basis.
