ENTITYTRAP_1.3.6.1.4.1.2011.5.25.219.2.14.5 hwFWDCPUUtilizationRising

Description

ENTITYTRAP/2/FWDCPUUSAGERISING: OID [oid] FWD CPU utilization exceeded the pre-alarm threshold.(FwdCoreIndex=[INTEGER], HwEntityPhysicalIndex=[INTEGER], PhysicalName="[OCTET]", EntityThresholdType=[INTEGER], EntityThresholdWarning=[INTEGER], EntityThresholdCurrent=[INTEGER], EntityTrapFaultID=[INTEGER])

The forwarding CPU usage exceeds the alarm threshold.

Attribute

Alarm ID	Alarm Severity	Alarm Type
1.3.6.1.4.1.2011.5.25.219.2.14.5	Major	equipmentAlarm(5)

Parameters

Name	Meaning
OID	Indicates the ID of a MIB object.
FwdCoreIndex	Indicates the forwarding CPU entity index.
HwEntityPhysicalIndex	Indicates a physical index.
PhysicalName	Indicates the name of the physical entity.
EntityThresholdType	Indicates the threshold type.
EntityThresholdWarning	Indicates the alarm threshold value.
EntityThresholdCurrent	Indicates the current value.
EntityTrapFaultID	Indicates the error code.

Impact on the System

Packet loss may occur during traffic forwarding.

Possible Causes

Cause 1: The CPU usage alarm threshold is set too low.

Cause 2: The service traffic is heavy. For example, broadcast flooding occurs, a physical loop occurs, or the Internet access traffic is heavy.

Cause 3: Too many services are enabled on the device.

Cause 4: The device is being attacked.

Procedure

Run the display cpu-usage configuration command to check whether the alarm threshold for the forwarding CPU usage is set properly.
- If so, go to step 3.
- If not, go to step 2.
Run the set cap cpu-usage threshold command to set a proper alarm threshold for the forwarding CPU usage. Then, check whether the alarm persists.
- If the alarm persists, go to step 3.
- If the alarm is cleared, no further action is required.
Check whether there are a large number of services, such as broadcast flooding, physical loops, and heavy Internet access traffic.
- If broadcast flooding occurs, run the display cap cpu-usage verbose command in the diagnostic view to check the CPU usage of broadcast, unicast, and multicast packets. If these packets occupy many CPU resources, configure functions such as traffic optimization in large broadcast domain scenarios and ARP flood attack defense.
- If a physical loop exists, configure the STP function.
- If the Internet access traffic is heavy, limit the user rate or contact technical support personnel.
- If the traffic volume is low, go to step 4.
Collect alarm messages, log messages, and configurations, run the display cpu-usage command in the diagnostic view to collect CPU usage details, and contact technical support personnel.
