Configuring the SD and SF Alarm Threshold
Context
Different services allow different bit error rates. You can configure the error rate alarm threshold for a POS interface so that an alarm is reported when the link performance deteriorates. Network administrators can locate and process link faults based on the alarms.
The Signal Degrade (SD) and Signal Fail (SF) alarms indicate the current link performance. Their generation reasons are both that the receiver detects error codes. The difference is that an SD alarm is reported when a small number of error codes are detected and an SF alarm is reported when a large number of error codes are detected.
Procedure
- Run system-view
The system view is displayed.
- Run interface pos interface-number
The POS interface view is displayed.
- Run threshold { sd | sf } value
The SD and SF alarm threshold is configured for the POS interface.
The default SD alarm threshold is 10e-6 and the default SF alarm threshold is 10e-3.
The SD alarm threshold must be smaller than the SF alarm threshold.
