| ciscoIfLoopbackMIB | 1.3.6.1.4.1.9.9.9399 | | | The MIB module to configure the loopback on certain interfaces
in ifTable with ifType ds1/e1, ds3/e3, ds0 etc. |
| ciscoIfLoopbackMIBObjects | 1.3.6.1.4.1.9.9.9399.1 | | | |
| ciscoIfLoopbackConfig | 1.3.6.1.4.1.9.9.9399.1.1 | | | |
| cifLConfTable | 1.3.6.1.4.1.9.9.9399.1.1.1 | | not-accessible | This table contains configuration, control and status
parameters for performing loopback on an interface
in the ifTable. |
| cifLConfEntry | 1.3.6.1.4.1.9.9.9399.1.1.1.1 | | not-accessible | An entry can be created or deleted in this table
for an entry in the ifTable. An entry created in this
table puts the interface specified by ifIndex
in loopback state. An entry deleted from this table
removes the loopback from the interface specified by
ifIndex. The ifIndex refers to a unique value for an
interface in the ifTable.
Entry is deleted from this table if corresponding
ifTable entry is deleted. |
| INT cifLLoopback | 1.3.6.1.4.1.9.9.9399.1.1.1.1.1 | INTEGER | read-create | This object specifies the type of loopback to be established.
This object is required in order to complete the creation of a
row in this table. It cannot be modified when the cifLRowStatus
is active(1).
Possible values are :
farEndLineLoopback(1): This loopback occurs at the CPE upon
receiving a special code from the
device which initiates the loopback.
Upon receiving the loop activation request
code, CPE enters a Line loop mode in which it
returns the entire line back to the initiator.
The CPE will continue to return the data
back to the initiator until it receives
a loopback deactivation request code.
farEndPayloadLoopback(2): This loopback occurs at the CPE
upon receiving a special code from the
device which initiates the loopback.
Upon receiving the loop activation request
code, CPE enters a Payload loop mode in which it
returns the Payload of the received data back
to the initiator.
The CPE will continue to return the data
back to the initiator until it receives
loopback deactivation request code.
remoteLineLoopback(3): This loopback is established at the
Near-end. In this loopback the entire line is looped
back to the Far-end with a) bit-sequence integrity
maintained,
b) no change in framing, and c) no removal of bi-
polar violations.
remotePayloadLoopback(4): This loopback is established at
the Near-end. In this loopback the signal that is
returned to the Far-end consists of the payload of
the received signal (with bit sequence integrity
retained) and newly generated framing information.
localLoopback(5): This is also known as metallic loopback.
This loopback is used for checking the
internal circuitry of the T3/E3, T1/E1
device. Only for physical lines. |
| INT cifLLoopbackStatus | 1.3.6.1.4.1.9.9.9399.1.1.1.1.2 | INTEGER | read-only | This object shows the current status of loopback.
The value for this object is valid only when
cifLRowStatus is active(1).
Possible values for this object:
completed(1): Loopback is successfully completed.
inProgress(2): loop up or loop down in progress.
clockOutOfSync(3): When the send and receive clocks are not
synchronized.
failed(4) : Loopback failed. |
| INT cifLFELoopbackDeviceAndCode | 1.3.6.1.4.1.9.9.9399.1.1.1.1.3 | INTEGER | read-create | This object specifies the type of the end device and
the type of mechanism used to establish the loopback.
Loopback type may not be modified once the farend loopback
is established.
Latching Loopback: Latching Loopback is appropriate with
64 kbit/s DS0-A rate. Once invoked by a specific activation
sequence, it typically remains in effect until released by
another specific code sequence.
non-latching loopback: Non latching activation involves
continuous transmission of loopback command codes, followed
by test data interspersed with command codes.
nonLatchOCUwithOneDevice(1): Non-latching OCU with
one device.
nonLatchOCUwithChainDevices(2): Non-latching OCU
with chain of devices.
nonLatchCSU(3): Non-latching CSU.
nonLatchDSU(4): Non-latching DSU.
latchDS0Drop(5): Latching DS0-DP Drop device.
latchDS0Line(6): Latching DS0-DP line device.
latchOCU(7): Latching OCU.
latchCSU(8): Latching CSU.
latchDSU(9): Latching DSU.
latchDSU(9): Latching DSU .
latchHL96(10): Latching HL96 device.
v54PN127Polynomial(8): For fractional T1.
This loopback is based on
CCITT-ITU V.54 and is
used to place either a single
DS0 or a DS0 Bundle(N*DS0) in
loopback mode.
lineInband(12): This is used to loop back the
entire T1 line at the far end.
This is a repeating 5-bit
pattern(00001), i.e. 00001000010001....
lineLoopbackESF(13): This loopback results in a full
1.544Mbit/s loopback of the
incoming signal at the far end.
The loopback is activated (latched) and
deactivated by a bit sequence defined in
ANSI T1.403 - 1995.
This corresponds to Facility Data Link
(FDL) loopbacks on a T1 channel.
This causes a repeating, 16-bit ESF data
link code word (00001110 11111111) to be
sent to the remote end requesting that it
enter into a network line loopback.
payloadLoopbackESF(14): This loopback results in
1.536 Mbit/s
loopback of the payload of the incoming
signal at the far end. The loopback
is activated(latched) and deactivated
by a bit sequence defined in
ANSI T1.403 - 1995.
This corresponds to Facility Data Link
(FDL) loopbacks on a T1 channel.
This causes a repeating, 16-bit ESF data
link code word (00010100 11111111) to be
sent to the remote end requesting that it
enter into a network payload loopback.
noCode (15): LoopBack is on this device - NearEnd.
lineLoopbackFEAC(16): The FEAC channel is used to request
a line loopback
at the Far-end. Loopback activate and
de-activate are specified using the
code-words specified in ANSI T1.404-1994.
smartJackInband(17): Inband loop code for SmartJack (a Telco owned
device that represents the demarcation point of T1 service),

| ROW cifLRowStatus | 1.3.6.1.4.1.9.9.9399.1.1.1.1.4 | RowStatus | read-create | This object is used for creating a new row or delete an
existing row in this table.
In order to successfully create a row and set the value
of this object to active(1), cifLLoopback and
cifLFELoopbackDeviceAndCode must be set with desired values.
The value of this object can be set to notInService(2) to
disable the loopback. |
