Description

IPLPM/2/IPLPM_TRAP_GLOBAL_LOSSRATIO_EXCEED: OID [OID] The global packet loss ratio exceeded the upper threshold in five consecutive intervals. (PeriodHigh=[ULONG], PeriodLow=[ULONG], LossPkts=[COUNTER64], LossRatio=[LONG], PeriodNo=[COUNTER64])

In device packet loss measurement, the packet loss ratios in five consecutive intervals exceeded 5%.

Parameters

Name	Meaning
OID	Indicates the MIB object ID of the alarm.
PeriodHigh	Indicates the high bit in measurement interval number.
PeriodLow	Indicates the low bit in measurement interval number.
LossPkts	Indicates the number of packets lost.
PktLossRatio	Indicates the packet loss ratio.
PeriodNo	Indicates the measurement interval number.

Impact on the System

The forwarding performance of the device is affected.

Possible Causes

Packets received and sent by the device are not all known IP unicast packets. This alarm is generated if the device adds MPLS or VPN labels when forwarding known IP unicast packets.
Other causes are as follows: Packets are discarded by CAR or ACL, no route is found for the packets, IP packets are discarded due to TTL timeout, or invalid packets are discarded.

Procedure

Check whether packets received and sent by the device are all known IP unicast packets.
- If so, go to step 4.
- If not, go to step 2.
Check whether the device needs the MPLS or VPN service.
- If so, this alarm is informational only, and no action is required. To avoid generating this alarm, delete the iPCA configuration on the device if possible.
- If not, go to step 3.
Delete the MPLS or VPN service from the device, and check whether the device generates a clear alarm IPLPM_1.3.6.1.4.1.2011.5.25.328.2.2 hwIplpmGlobalLossRatioRecovery after 10 measurement intervals.
- If so, no further action is required.
- If not, go to step 4.
For details about the packet loss causes and troubleshooting methods, see "Fault Locating Guide - Software Troubleshooting - Packet Loss" in the Huawei S Series Campus Switches Troubleshooting Guide. Check whether the device generates a clear alarm IPLPM_1.3.6.1.4.1.2011.5.25.328.2.2 hwIplpmGlobalLossRatioRecovery after 10 measurement intervals.
- If so, no further action is required.
- If not, go to step 5.
Collect alarm information and configuration information, and then contact technical support personnel.
