ISIS-STD_1.3.6.1.2.1.138.0.1 isisDatabaseOverload

Description

ISIS-STD/3/OLOAD:OID [oid] The overload state of IS-IS LSDB changed. (sysLevel=[integer], NotificationSysLevelIndex=[integer], OverLoadState=[integer])

The IS-IS LSDB entered or exited from the overload state.

Attribute

Alarm ID	Alarm Severity	Alarm Type
1.3.6.1.2.1.138.0.1	Minor	other(1)

Parameters

Name	Meaning
oid	Indicates the MIB object ID of the alarm.
SysLevel	IS-IS level: 1: Level-1 2: Level-2
NotificationSysLevelIndex	IS-IS level of a device that sends the trap
OverLoadState	Overload state

Impact on the System

1. If the trap is generated because the IS-IS LSDB entered or exited from the overload state, route selection on the IS-IS neighbor will be affected.

2. If the trap is generated because the memory usage exceeds the upper threshold, the IS-IS LSDB is unreliable.

Possible Causes

Cause 1: The set-overload or undo set-overload command was run in the IS-IS view.

Cause 2: After the set-overload on-startup command was run in the IS-IS view, the wireless access controller restarted.

Cause 3: Applying for memory resources failed in the case of memory shortage, causing a system crash.

Procedure

Run the display this command in the IS-IS view to check whether the set-overload command has been run in the process.
- If set-overload command has been run in the process, go to Step 6.
- If set-overload command has not been run in the process, go to Step 2.
Run the display history-command command in any view to check whether the undo set-overload command has been run in the process.
- If the undo set-overload command has been run in the process, go to Step 6.
- If the undo set-overload command has not been run in the process, go to Step 3.
Run the display memory-usage command to check whether the memory usage of the wireless access controller has reached the upper threshold.
- If the memory usage has reached the upper threshold, go to Step 4.
- If the memory usage has not reached the upper threshold, go to Step 5.
Obtain the logs.
Collect alarm information and configuration information, and then contact technical support personnel.
End.
