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 U2000 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 U2000 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.
Clearing the Audible and Visual Alarm Indication of an NE Cabinet Temporarily
When an alarm is raised from an NE, the NE cabinet displays different visual alarms and generates different audible alarms according to the alarm severities. You can clear these audible and visual alarms by using the U2000 Web LCT.
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.
Setting Triggered Alarm Insertion
This topic describes how to implement the triggered alarm insertion to ensure that protection switching functions properly. In a network consisting of different IF cards that support different switching mechanisms for the SNCP ring, triggered alarm insertion is necessary.
Browsing Microwave Link Alarms The topic describes how to browse microwave link alarms to obtain the important intermediate frequency information and alarm information of the NEs on both ends of a microwave link.
