This value contains the object identifier that uniquely
describes the circuit that is to be added to this table.
The object identifier should be that of the first field
on the table that contains the circuit. The index sub
identifiers should uniquely define the circuit.
The purpose of this object identifier is to point a
network manager to the table in which the circuit was
created as well as define the circuit on which the
interface is defined.
Valid tables for this object are the frCircuitTable from
the Frame Relay DTE MIB(FRAME-RELAY-DTE-MIB) or the
frPVCEndptTable from the Frame Relay Service MIB
(FRNETSERV-MIB). However, it does not exclude enterprise
MIBs used for the same purpose.
The direction of data flow through the circuit for which
the virtual interface is defined. The following define
the information that the virtual interface will report.
transmit(1) - Only transmitted frames
receive(2) - Only received frames
both(3) - Both transmitted and received frames.
The need to monitor directional flow depends on the
application for which the circuit is created. For example,
Monitoring of protocols passed on a circuit using
RMON-II (RFC 2021) does not capture the direction the flow.
This is left to the circuit.
The status of the current row. This object is
used to add, delete, and disable rows in this
table. When the status changes to active(1), a row
will also be added to the interface map table below
and a row will be added to the ifTable. These rows
SHOULD not be removed until the status is changed
from active(1). The value of ifIndex for the row that
is added to the ifTable is determined by the agent
and MUST follow the rules of the ifTable. The value
of ifType for that interface will be .
When this object is set to destroy(6), the associated
row in the interface map table will be removed and the
ifIndex will be removed from the ifTable. Removing
the ifIndex MAY initiate a chain of events that causes
changes to other tables as well.
The rows added to this table MUST have a valid object
identifier for frciCircuitObject. This means that the
referenced object must exist and it must be in a table
that supports circuits.
The object referenced by frciCircuitObject MUST exist
prior to transitioning a row to active(1). If at any
point the object referenced by frciCircuitObject does not
exist or the row containing it is not in the active(1)
state, the status SHOULD report notReady(3). The effects
transitioning from active(1) to notReady(3) are the same
as those caused by setting the status to destroy(6).
