STORM_CUR_QUENUM_OVER

STORM_CUR_QUENUM_OVER

Description

The STORM_CUR_QUENUM_OVER alarm indicates a storm. When the number of current alarms on the NE reaches the value that is equal to the maximum number of alarms supported by an alarm queue minus one, the alarm is reported. The alarm cannot be wrapped by other alarms on the NE.

Attribute

Alarm Severity Alarm Type

Minor

Equipment alarm

Parameters

None.

Impact on the System

When the alarm is reported, services are not affected. When the count of current alarms on the NE reaches a certain value, the alarm is reported to prompt the user that the alarm queue is full. In this case, certain alarms in the system control, switching, and timing board database are lost due to the alarm storage mode.

Possible Causes

The possible cause of the STORM_CUR_QUENUM_OVER alarm is as follows:

The alarm queue is insufficient to contain all current alarms.

Procedure

  1. Check the queue of current alarms on the U2000. Identify and clear the frequently reported alarms (STORM_CUR_QUENUM_OVER excluded). When the count of alarms in the alarm queue is decreased to a specified value, the alarm is cleared automatically.

Related Information

Alarm Storage

The NE register stores the alarm data by "Stopping" and "Wrapping". The NE uses the "Wrapping" mode by default.

  • When the storage mode is "Stopping", if the count of alarms reaches the capacity threshold of the register, new alarms are discarded.
  • When the alarm storage mode is "Wrapping", if the count of alarms reaches the capacity threshold, new alarms overwrite earlier alarms and the new alarms are stored from the start address of the register.
