ciCircuitObject OBJECT-TYPE
SYNTAX RowPointer
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"This value contains the RowPointer that uniquely
describes the circuit that is to be added to this table.
Any RowPointer that will force the size of OBJECT
IDENTIFIER of the row to grow beyond the legal limit
MUST be rejected.
The purpose of this object 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 include the frCircuitTable
from the Frame Relay DTE MIB(FRAME-RELAY-DTE-MIB), the
frPVCEndptTable from the Frame Relay Service MIB
(FRNETSERV-MIB), and the aal5VccTable from the ATM MIB
(ATM MIB). However, including circuits from other MIB
tables IS NOT prohibited."
::= { ciCircuitEntry 1 }
ciCircuitFlow OBJECT-TYPE
SYNTAX CiFlowDirection
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"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.
It is recommended that the ifDescr of the circuit
interfaces that are not both(3) SHOULD have text warning
the operators that the particular interface represents
only half the traffic on the circuit."
::= { ciCircuitEntry 2 }
ciCircuitStatus OBJECT-TYPE
SYNTAX RowStatus
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"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 frDlciEndPt(193)
for a frame relay circuit, atmVciEndPt(194) for an
ATM circuit, or another ifType defining the circuit
type for any other circuit.
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 ciCircuitObject. This means that the
referenced object must exist and it must be in a table
that supports circuits.
The object referenced by ciCircuitObject MUST exist
prior to transitioning a row to active(1). If at any
point the object referenced by ciCircuitObject does not
exist or the row containing it is not in the active(1)
state, the status SHOULD either age out the row or
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).
Each row in this table relies on information from other
MIB modules. The rules persistence of data SHOULD follow
the same rules as those of the underlying MIB module.
For example, if the circuit defined by ciCircuitObject
would normally be stored in non-volatile memory, then
the row SHOULD also be non-volatile."

DESCRIPTION
"This object returns the value of sysUpTime at the time

this object SHOULD return 0."
