IFPDT_1.3.6.1.4.1.2011.5.25.157.2.157.20 hwPhysicalPortInBroadcastRapidChange

Description

IFPDT/4/PORT_INBRDCAST: OID [oid] The rapid-change of input broadcast exceeded the threshold. (IfIndex=[INTEGER], InterfaceName=[STRING], InputBroadcastChangeThreshold=[INTEGER]pps, CurrentInputBroadcastRate=[COUNTER64]pps, BaseInputBroadcastRate=[COUNTER64]pps)

The difference (increase or decrease) in the broadcast traffic volume change in the inbound direction of interfaces exceeded the threshold.

Attribute

Alarm ID Alarm Severity Alarm Type
1.3.6.1.4.1.2011.5.25.157.2.157.20 Warning qualityOfServiceAlarm(3)

Parameters

Name Meaning

oid

Indicates the MIB object ID of the alarm.

IfIndex

Indicates the interface index.

InterfaceName

Indicates the interface name.

InputBroadcastChangeThreshold

Indicates the threshold of the broadcast packet rate change in the inbound direction of interfaces.

CurrentInputBroadcastRate

Indicates the broadcast packet rate in the inbound direction of interfaces in the current traffic statistics collection interval.

BaseInputBroadcastRate

Indicates the base broadcast packet rate in the inbound direction of interfaces.

Impact on the System

  • If the CurrentInputBroadcastRate value is greater than or equal to the sum of the BaseInputBroadcastRate and InputBroadcastChangeThreshold values, packet loss may occur on the switch.
  • If the CurrentInputBroadcastRate value is less than or equal to the BaseInputBroadcastRate value minus the InputBroadcastChangeThreshold value, there is no impact.

Possible Causes

  • If the CurrentInputBroadcastRate value is greater than or equal to the sum of the BaseInputBroadcastRate and InputBroadcastChangeThreshold values, a loop might occur on the network and caused a broadcast storm.
  • If the CurrentInputBroadcastRate value is less than or equal to the BaseInputBroadcastRate value minus the InputBroadcastChangeThreshold value, the broadcast traffic volume in the inbound direction of interfaces restored.

The sudden traffic volume increase trap and sudden traffic volume change clear trap are timed respectively. After a sudden traffic volume increase trap or sudden traffic volume change clear trap is generated, the switch will not generate the trap again within 10 minutes.

Procedure

  • If the CurrentInputBroadcastRate value is greater than or equal to the sum of the BaseInputBroadcastRate and InputBroadcastChangeThreshold values, check whether the broadcast traffic volume increase is normal. If not, check whether a loop exists on the link.
  • If the CurrentInputBroadcastRate value is less than or equal to the BaseInputBroadcastRate value minus the InputBroadcastChangeThreshold value, this trap is informational only, and no action is required.
