IFNET_1.3.6.1.4.1.2011.5.25.41.4.1 hwIfMonitorCrcErrorRising

Description

IFNET/1/CRCERRORRISING: OID [oid] The CRC error is rising. (hwIfMonitorIndex=[INTEGER], hwIfMonitorCrcErrorStatistics=[COUNTER64], hwIfMonitorCrcErrorThreshold=[INTEGER], hwIfMonitorCrcErrorInterval=[INTEGER], InterfaceName=[STRING])

The trap is generated if the number of CRC errors exceeds the specified value in the specified time.

Attribute

Alarm ID	Alarm Severity	Alarm Type
1.3.6.1.4.1.2011.5.25.41.4.1	Critical	other(1)

Parameters

Name	Meaning
OID	Indicates the MIB object ID of the alarm.
hwIfMonitorIndex	indicates the interface index.
hwIfMonitorCrcErrorStatistics	indicates statistics on CRC errors.
hwIfMonitorCrcErrorThreshold	indicates the threshold for CRC trap (a trap is generated if the number of CRCs exceeds the threshold).
hwIfMonitorCrcErrorInterval	indicates the time period for collecting CRC error statistics.
InterfaceName	indicates the interface name.

Impact on the System

Data of some services on the interface will be dropped.

Possible Causes

The number of packets that are dropped because they failed the CRC exceeded the threshold.

The possible causes are as follows:

1. The optical module was faulty.

2. The optical fiber was faulty.

Procedure

Replace the optical module and then check whether the fault is rectified.
1. If so, go to step 4.
2. If not, go to step 2.
Replace the optical fiber, and then check whether the fault is rectified.
1. If so, go to step 4.
2. If not, go to step 3.
Collect alarm information and configuration information, and then contact technical support personnel.
End.
