show interfaces diagnostics optics (SONET)

 

Syntax

Release Information

Command introduced in Junos OS Release 7.5.

Description

(M320, T320, T640, and T1600 routers only) For SONET/SDH interfaces that support optical diagnostics and monitoring, display transceiver diagnostics and data alarms.

Options

so-fpc/pic/portSONET/SDH interface name.

Additional Information

The transceivers are polled in 1-second intervals for diagnostics data, alarms, and warnings and stores them into memory. The alarms will not cause the links to go down or the LEDs to change color or generate SNMP traps. Changes in alarm and warning status will generate system log messages.

Thresholds that trigger a high alarm, low alarm, high warning, or low warning are set by the transceiver vendors. Generally, a high alarm or low alarm indicates that the optics module is not operating properly. This information can be used to diagnose why a PIC is not working.

In the output fields, when an alarm is On, this indicates an error condition. Alarm Off indicates normal operation.

Note

The show interfaces diagnostics optics command for optical interfaces does not report the decibel (dBm) value of the received signal if the received power is zero milliwatts (0.0000 mW).
