Alarm Configuration
Introduction to Alarm
Sampling and Alarms
Sampling means the system retrieves statistics data at the sampling interval
At the alarm monitor interval, the system samples the alarm variables and will trigger an alarm if the
value of a variable exceeds its alarm threshold. Alarm information can be output to the network
management system or alarm buffer by configuring the information center.
The alarms can be global alarms, OLT port alarms, or ONU port alarms.
When an alarm configuration command is executed in FTTH view, the command takes effect on all
the OLT ports and all the ONUs attached to the OLT ports.
When an alarm configuration command is executed in OLT port view, the command takes effect on
the current OLT port and all the ONUs attached to the OLT port.
When an alarm configuration command is executed in ONU port view, the command takes effect
only on the ONU corresponding to the current ONU port.
