Description

IFPDT/4/PORT_OUTRATECHG: OID [OID] The output rate change ratio exceeded the threshold. (IfIndex=[INTEGER], InterfaceName=[STRING], ThresholdPercent=[INTEGER]%, CurrentStatisticalPeriodRate=[COUNTER64], LastStatisticalPeriodRate=[COUNTER64])

The sudden traffic volume change percentage in the outbound direction of interfaces exceeded the trap threshold.

Attribute

Alarm ID	Alarm Severity	Alarm Type
3276800088	Warning	Quality of service alarm

Parameters

Name	Meaning
OID	Indicates the MIB object ID of the alarm.
IfIndex	Indicates the interface index.
InterfaceName	Indicates the interface name.
ThresholdPercent	Indicates the detection threshold of sudden traffic volume changes.
CurrentStatisticalPeriodRate	Rate of bytes on the interface in the current traffic statistics collection interval.
LastStatisticalPeriodRate	Rate of bytes on the interface in the previous traffic statistics collection interval.

Impact on the System

Packet loss may occur on interfaces.

Possible Causes

The sudden traffic volume change percentage in the outbound direction of interfaces exceeded the trap threshold.

Procedure

Run the display this interface command to view the Output bandwidth utilization field, and check whether the sudden traffic in the inbound direction of interfaces is normal.
- If so, no action is required.
- If not, check whether a loop exists on the link.
Collect log information, and contact technical support personnel.
