An alarm refers to the notification MA5600T of the system after a fault is detected. After an alarm is generated, the system broadcasts the alarm to the terminals, mainly including the NMS and command line interface (CLI) terminals.

Alarms are classified into fault alarm and recovery alarm. After a fault alarm is generated at a certain time, the fault alarm lasts till the fault is rectified to clear the alarm.

You can modify the alarm settings according to your requirements. The settings are alarm severity, alarm output mode through the CLI and alarm statistics switch.

When managing alarms on the GUI through the NMS, you can set filtering criteria to mask unimportant alarms and events. Such filtering function facilitates the focus of the important alarms and eliminates the load of the NMS.

Procedure

The output of all alarms at level warning is shielded to the CLI terminal, the alarm jitter-proof function is enabled, the alarm jitter-proof period is set to 15s, the level of alarms with IDs 0x0a310021 and 0x2e314021 are modified to critical, do as follows:

huawei(config)#undo alarm output alarmlevel warning

huawei(config)#alarm jitter-proof on

huawei(config)#alarm jitter-proof 15

huawei(config)#alarm alarmlevel 0x0a310021 critical

huawei(config)#alarm alarmlevel 0x2e314021 critical

To create ONT alarm policy profile 10, filter the following alarms, and bind this profile to GPON ONT 1 connected to port 0/3/0, do as follows:

0x2e112003 (The signal degrade of ONTi (SDi) occurs)

0x2e112004 (The signal fail of ONTi (SFi) occurs)

0x2e112006 (The loss of frame of ONTi (LOFi) occurs)

0x2e313015 (The hardware of the ONT is faulty)

0x2e313016 (The ONT switches to the standby battery)

0x2e313017 (The standby battery of the ONT is lost)

0x2e313018 (The standby battery of the ONT cannot be charged)

0x2e313019 (The voltage of the standby battery of the ONT is too low)

0x2e31301a (The shell of the ONT is opened)

0x2e313024 (The loss of signals occurs on the ethernet port of the ONT)

0x2e313025 (No signal is received in the video UNI of the ONT)

0x2e31302a (The E1/T1 port loss of signal (LOS) occurs at the ONT)
