SECE/4/OLC_DROP_PACKET

Message

SECE/4/OLC_DROP_PACKET: Some packets are dropped because cpu is overloaded on the board in slot [STRING]. (Protocol=[STRING], PassedPacketCount= [ULONG], DroppedPacketCount=[ULONG])

Description

The CPU usage reached the OLC start threshold, and the monitored protocol packets were discarded.

Parameters

Parameter Name	Parameter Meaning
slot	Indicates the slot ID.
Protocol	Indicates the protocol type of packets.
PassedPacketCount	Indicates the number of passed packets.
DroppedPacketCount	Indicates the number of discarded packets.

Possible Causes

A large number of packets of a monitored protocol were sent to the CPU or an attack was initiated.

Procedure

Run the display cpu-usage command to view the current CPU usage.
Run the display cpu-overload-control statistics command to view OLC statistics to locate the type of discarded protocol packets.
If the CPU usage is within the acceptable range, run the cpu-overload-control packet-type disable command to disable the OLC function for the protocol. Otherwise, no further action is required.
