ALM-67706884 hwRuPortCrcErrorRising

Description

Remote unit CRC error is rising. (RemoteUnitEsn=[RemoteUnitEsn], InterfaceName=[InterfaceName], CrcErrorStatistics=[CrcErrorStatistics], CrcErrorThreshold=[CrcErrorThreshold], CrcErrorInterval=[CrcErrorInterval](s))

The number of interface CRC errors on the remote module exceeded the threshold.

This alarm is supported only on S5735-L-V2, S5735-S-V2, S5735I-S-V2, S5735I-L-V2, S6730-H-V2, S5732-H-V2.

Parameters

Parameter	Description
RemoteUnitEsn	ESN of the remote module.
InterfaceName	Port number of the remote module.
CrcErrorStatistics	Statistics in a CRC period.
CrcErrorThreshold	CRC alarm threshold. The value is fixed at 20.

Impact on the System

Some service data on the port is discarded.

Possible Causes

Cause 1: transceiver fault.
Cause 2: Fiber failure.

Procedure

Cause 1: transceiver fault.
Replace the optical module and check whether the alarm is cleared.
- If so, no further action is required.
- If not, collect alarm and configuration information, and contact technical support.
Cause 2: Fiber failure.
Replace the optical fiber and check whether the alarm is cleared.
- If so, no further action is required.
- If not, collect alarm and configuration information, and contact technical support.
