Huawei Gpon ONT Alarm Profile Configure

by

Huawei Gpon ONT Alarm Profile:

Today i will describes how to add an alarm profile, and configure most of the performance parameters for various ONT lines as a profile. After the alarm profile is configured and bound successfully, the ONT can directly use the profile when it is activated. [boxads]

An ONT alarm profile defines a series of alarm thresholds that are used to monitor the performance of an activated ONT line. When the statistics result of a parameter reaches the alarm threshold, the NE is notified and an alarm is sent to the log server and the NMS.

  • The MA5600T/MA5603T/MA5608T supports up to 50 alarm profiles.
  • The system contains a default alarm profile with the ID 1. This profile cannot be deleted but can be modified.

Procedure:

  • Step-1: Run the gpon alarm-profile add command to add a GPON ONT alarm profile. All parameters in the default profile are set to 0, which indicates that no alarm is reported. When an alarm profile is created, the default values of all alarm thresholds are 0, which indicates that no alarm is reported.
  • Step-2: Run the display gpon alarm-profile command to query the alarm profile.

ONT Alarm Profile Configuration Example:

[adsense] To add Huawei GPON ONT alarm profile 5, set the alarm threshold for the packet loss of the GEM port to 10, set the alarm threshold for the number of mis-transmitted packets to 30, and use the default value 0 for all other thresholds, do as follows:
