Parameters

Parameter	Description	Value
interface-number	Specifies the number of an interface.	-
los	Indicates the signal loss alarm. This alarm is caused by a poor link.	-
lof	Indicates the frame loss alarm. This alarm is caused by a poor physical link or low clock precision.	-
lais	Indicates the line alarm.	-
oof	Indicates the frame loss alarm. If consecutive five frames are not received, an OOF alarm will be generated.	-
lrdi	Indicates the line remote defect alarm.	-
lcd	Indicates the loss of Code Group Synchronization.	-
auais	Indicates the administrative unit alarm.	-
b3tca	Indicates the B3 threshold crossing alarm.	-
lom	Indicates the tributary multiframe loss alarm.	-
lop	Indicates the pointer loss alarm. If consecutive eight frames received by pointer J1 are invalid, the LOP alarm will be generated.	-
lrei	Indicates the line remote error alarm.	-
pais	Indicates the path alarm.	-
prdi	Indicates the path remote defect alarm.	-
prei	Indicates the path remote error alarm.	-
pplm	Indicates the path payload mismatch alarm.	-

rdool	Indicates the receive data out of lock.	-
rrool	Indicates the receive reference out of lock.	-
sdbere	Indicates the signal degrade threshold alarm.	-
sfbere	Indicates the signal failure threshold alarm.	-
trool	Indicates the out-of-lock alarm of the transmitted reference clock.	-
wlnk	Indicates the WAN interface status alarm. The statistics of WLNK alarms can be displayed on 10GE WAN interfaces only.	-

Usage Guidelines

Usage Scenario

This command can be used to view the alarm status and alarm statistics on an interface.

Prerequisites

The transmission-alarm damping command has been run.

Precautions

WLNK alarms are always enabled and cannot be configured. You can run only the display transmission-alarm command to view the statistics of WLNK alarms.

Example

The actual command output varies according to the device. The command output here is only an example.
