To ensure the normal running of the network, the network management and maintenance staff should periodically check and monitor the network by taking appropriate alarm management measures.
Basic Concepts
Alarm is the primary information source for you to learn the network running status and to locate faults. Hence, you need to familiarize yourself with the basic concepts and related operations of the alarm management so that you can effectively obtain and manage the alarms.
Viewing Alarms
The network maintenance personnel can view alarms to know the network status.
Suppressing Alarms
You can suppress alarms, so that the Web LCT does not monitor these alarms. These alarms can be generated from networkwide equipment, a particular NE, board, or even from a particular functional module of a board.
Setting Alarm Reversion for a Specified Port
During a new deployment, certain alarms that are reasonable but meaningless occur. For example, when you configure a tributary board, line board, or Ethernet board for a service but not connect cables, the corresponding LOS alarm is generated. After the alarm reversion is set, the alarm is not displayed. This does not affect the network monitoring that is performed by maintainers.
Setting Automatic Reporting Status for Alarms of a Board
You can set the automatic reporting status of the alarms of specific boards so that the Web LCT only monitors important alarms, thus improving the network maintenance efficiency. To implement the function, you can manually set the automatic reporting status for each alarm.
Modifying the Alarm Severity for a Board
You can modify the severity of the board alarms according to the requirement. In this way, you can focus on the important alarms, thus facilitating maintenance.
Specifying the Port QoS Alarm
You can set the QoS for a port depending on whether there are services on the port or whether the services are important. In this way, you can effectively manage alarms. You can set the QoS by specifying the bit error alarm threshold and setting the port switching conditions.
Setting NE Alarm Attributes
You can set NE alarm attributes to effectively decrease the occurrence frequency of invalid alarms and to improve the efficiency of alarm monitoring.
Enabling the Alarm Monitoring for Lower Order Paths
If you enable the alarm monitoring function for the lower order paths when you configure lower order services in a VC4 higher order path, you can monitor the alarms of an individual lower order path.
