Description

WLAN/4/AP_MEM_OVERLOAD: OID [oid] AP memory overload notify.(APMAC=[OPAQUE], APName=[STRING], ApMemRate=[INTEGER], APID=[INTEGER])

The AP's memory usage exceeded the upper threshold.

Attribute

Alarm ID Alarm Severity Alarm Type
1.3.6.1.4.1.2011.6.139.13.1.1.9 Warning equipmentAlarm(5)

Parameters

Name Meaning
oid Indicates the ID of the MIB object.
APMAC Indicates the MAC address of an AP.
APName Indicates the AP name.
ApMemRate Indicates the AP's memory usage.
APID Indicates the AP ID.

Impact on the System

The memory usage exceeds the alarm threshold.

The default memory usage threshold of a cloud AP is 90%. If this threshold is exceeded, services may be affected, for example, the AP may suffer from packet loss or even go offline.

The memory usage threshold of a Fat AP can be adjusted. If the threshold is set to a medium value (such as 50 or 60), services are not affected when the threshold is exceeded. If the threshold is set high (such as 90), services may be affected when the threshold is exceeded, for example, the AP may suffer from packet loss.

Possible Causes

Cause 1: The memory alarm threshold is low.

Cause 2: The device provides too many services.

Procedure

  1. Run the display ap-system-profile command to check the alarm threshold for memory usage. Check whether the alarm threshold is set properly. On a cloud AP, go to step 3 directly.

    • If so, go to step 3.
    • If not, go to step 2.

  2. Run the memory-usage threshold command to set a proper alarm threshold for memory usage. Then, check whether the alarm persists.

    • If the alarm persists, go to step 3.
    • If the alarm is cleared, go to step 5.

  3. Delete unnecessary services and configurations to reduce memory usage. Then check whether the alarm is cleared.

    • If the alarm persists, go to step 4.
    • If the alarm is cleared, go to step 5.

  4. Collect alarms, logs, and configurations, and then contact technical support personnel.
  5. End.
