This table
describes selected fields from the
show controllers
dwdm command output.
Table 1. show
controllers dwdm Command Output Field Descriptions
Field
|
Description
|
AIS
|
Number of
alarm indication signal (AIS) alarms. AIS is a signal sent downstream as an
indication that an upstream defect has been detected.
|
Alarm
reporting enabled for
|
Lists the
alarms that are enabled for reporting.
|
Asserted
Alarms
|
Alarms
indicated to be reported by the user.
|
BDI
|
Number of
backward defect indication (BDI) alarms. The BDI is a single bit that conveys
information regarding signal failure in the upstream direction.
|
BER
thresholds
|
Values of
the configured bit error rate thresholds.
|
BIP
|
Number of
bit interleaved parity alarms. The BIP is comprised of one byte and is used for
error detection. It is computed over the entire optical channel payload unit
(OPU).
|
Controller
State
|
Status of
the controller.
|
Detected
Alarms
|
Alarms
detected by the hardware.
|
EC
|
Corrected
code words. This is the number of words corrected by the FEC and is displayed
as a per second rate.
|
FEC Mode
|
Indicates
the forward error correction (FEC) mode for the controller.
This can be Disabled,
Enhanced FEC G.975.1 1.7 (Default), or Standard FEC.
|
IAE
|
Number of
incoming alignment errors (IAE).
|
LCK
|
Number of
upstream connection locked alarms. LCK is a signal sent downstream as an
indication that upstream the connection is locked, and no signal is passed
through.
|
LOF
|
Number of
OTU loss of frame (LOF) alarms.
|
LOM
|
Number of
OTU loss of multiframe (LOM) alarms.

Loopback
status. Indicates whether or not loopback is enabled and the type of loopback
enabled.
|
LOS
|
Number of
OTU loss of signal (LOS) alarms.
The LOS threshold is set
using the
rx-los-threshold command. If the receive
optical power is less than or equal to this defined threshold, the optical LOS
alarm is raised.
|
OCI
|
Number of
open connection indication alarms. OCI is a signal sent downstream as an
indication that upstream the signal is not connected to a trail termination
source.
|
ODU
|
Optical
channel data unit alarms.
|
OTU
|
Optical
transport unit overhead alarms.
|
OTU TTI
Expected
|

Received
|
Value of
the received TTI.
|
OTU TTI
Sent
|
Value of
the transmit trail trace identifier (TTI).
|
PTIM
|
Number of
payload type identifier mismatch alarms. This occurs when there is a mismatch
between the way the ITU-T G.709 option is configured on the PLIM at each end of
the optical span.
|
TDC Info
|
Tunable
Dispersion Compensator (TDC) information.
|
Transport
Admin State
|
Current
status of the port as set by the
admin-state
command. Possible values are: IS (In-Service) and OOS (Out-of-Service).
|
UC
|
Uncorrectable code words. This is a raw counter.
|
Pre-FEC
BER
|
Pre - bit
error rate (BER) forward error correction (FEC). The pre-FEC BER is calculated
using pre-forward error correction (FEC) error counts.
|
Q
|
The
general signal quality bit error rate (BER) per voltage. The Q and Q margin are
calculated using the Pre-FEC BER.
|
Q Margin
|
The
general signal quality bit error rate (BER) per voltage. The Q and Q margin are
calculated using the Pre-FEC BER.
|
Operational Mode
|
Indicates
whether the tunable dispersion compensator (TDC) operational mode option is set
to Auto or Manual.
|
Status
|
Indicates
whether the tunable dispersion compensator (TDC) is in the acquiring state or
locked state. The status is invalid if there is a major alarm.
|
Dispersion
Setting
|
Indicates
a value between –700 and +700 packets per second (pps). The dispersion setting
is read from the optics module after the tunable dispersion compensator (TDC)
has locked.
|
Reroute
Control
|
Not used.
