IFPDT_1.3.6.1.4.1.2011.5.25.157.2.157.18 hwPortCrcRateExceed

Description

IFPDT/1/CRCRATEEXCEED: OID [OID] The interface CRC error rate exceeded the trap threshold, which may affect forwarding. Handle it as soon as possible. (InterfaceIndex=[INTEGER], InterfaceName=[OCTET], CrcRate=[OCTET], TrapThreshold=[OCTET])

The rate of receiving CRC error packets equals or exceeds 1000 packets per second.

Attribute

Alarm ID	Alarm Severity	Alarm Type
1.3.6.1.4.1.2011.5.25.157.2.157.18	Critical	qualityOfServiceAlarm(3)

Parameters

Name	Meaning
OID	Indicates the MIB object ID of the alarm.
InterfaceIndex	Indicates the interface index.
InterfaceName	Indicates the interface name.
CrcRate	Indicates the current rate of receiving CRC error packets.
TrapThreshold	Indicates the alarm threshold for the rate of receiving CRC error packets.

Impact on the System

This interface discards some service data.

Possible Causes

After the stacking function is enabled on the switch, the rate of receiving CRC error packets by an interface equals or exceeds 1000 packets per second. The possible causes include:

Cause 1:

The optical module is faulty.

Cause 2:

The optical fiber is faulty.

Procedure

Replace the optical module and run the display interface command to check whether the number of CRC error packets received by the interface keeps increasing.
1. If so, go to step 2.
2. If not, go to step 4.
Replace the optical fiber and run the display interface command to check whether the number of CRC error packets received by the interface keeps increasing.
1. If so, go to step 3.
2. If not, go to step 4.
Collect trap, log, and configuration information, and contact technical support personnel.
