DEFD/6/CPCAR_DROP_MPU

Message

DEFD/6/CPCAR_DROP_MPU:Rate of packets to cpu exceeded the CPCAR limit on the MPU. (Protocol=[STRING], CIR/CBS=[ULONG]/[ULONG], ExceededPacketCount=[STRING])

Description

The rate of packets delivered to the CPU exceeds the CPCAR limit on the MPU.

Parameters

Parameter Name Parameter Meaning
Protocol Indicates the protocol type.
CIR/CBS Indicates the committed information rate and committed burst size.
ExceededPacketCount Indicates the number of packets whose rate exceeds the CPCAR.

Possible Causes

The rate of packets delivered to the CPU exceeded the CPCAR limit on the MPU. As a result, some packets are discarded.

Procedure

  1. Control the rate of packets delivered to the CPU within the CPCAR limit, or run the car packet-type packet-type cir cir-value [ cbs cbs-value ] command to configure a proper CPCAR limit.

    Improper CPCAR settings will affect services on your network. If you need to adjust CPCAR settings, you are advised to contact technical support personnel for help.

DEFD/6/CPCAR_DROP_LPU

Message

DEFD/6/CPCAR_DROP_LPU:Rate of packets to cpu exceeded the CPCAR limit on the LPU in slot [STRING]. (Protocol=[STRING], CIR/CBS=[ULONG]/[ULONG], ExceededPacketCount=[STRING])

Description

The rate of packets delivered to the CPU exceeds the CPCAR limit on the specified LPU.

Parameters

Parameter Name Parameter Meaning
slot

Specifies the slot ID.

Protocol Indicates the protocol type.
CIR/CBS Indicates the committed information rate and committed burst size.
ExceededPacketCount Specifies the number of packets whose rate exceeds the CPCAR.

Possible Causes

The rate of packets sent to the CPU of the specified LPU exceeds the CPCAR.

Procedure

  1. Run the auto-defend enable command to configure attack source tracing. If a possible attack source is detected, check on the network to determine whether it is a real attack source.
  2. If a real attack source exists, run the blacklist command to add the attack source to the blacklist or run the auto-defend action command to configure a punish action for the attack source. If no attack source exists, run the car (attack defense policy view) command to increase the CPCAR value properly.

    Improper CPCAR settings will affect services on your network. If you need to adjust CPCAR settings, you are advised to contact technical support personnel for help.

DEFD/6/CPCAR_DROP_SLAVE

Message

DEFD/6/CPCAR_DROP_SLAVE:Rate of packets to cpu exceeded the CPCAR limit on the slaveboard. (Protocol=[STRING], CIR/CBS=[ULONG]/[ULONG], ExceededPacketCount=[STRING])

Description

The rate of packets delivered to the CPU exceeds the CPCAR limit on the slaveboard.

Parameters

Parameter Name Parameter Meaning
Protocol Indicates the protocol type.
CIR/CBS Indicates the committed information rate and committed burst size.
ExceededPacketCoun Indicates the number of packets whose rate exceeds the CPCAR.

Possible Causes

The rate of packets delivered to the CPU exceeded the CPCAR limit on the standby card. As a result, the standby card discarded some packets.

Procedure

  1. Control the rate of packets delivered to the CPU within the CPCAR limit, or run the car packet-type packet-type cir cir-value [ cbs cbs-value ] command to configure a proper CPCAR limit.

    Improper CPCAR settings will affect services on your network. If you need to adjust CPCAR settings, you are advised to contact technical support personnel for help.

DEFD/6/CPCAR_INVALID

Message

DEFD/6/CPCAR_INVALID:Packets are dropped because CPCAR is invalid. (Protocol=[STRING], slot=[STRING], CIR/CBS=[ULONG]/[ULONG])

NOTE:

Only the V200R013C00SPC500 version supports this log.

Description

Protocol packets were dropped because CPCAR was ineffective.

Parameters

Parameter Name Parameter Meaning
Protocol Indicates the protocol type.
slot

Indicates a slot ID.

CIR/CBS Indicates the committed information rate and committed burst size.

Possible Causes

Within the 5-minute detection interval, all CPU-bound protocol packets were discarded because the deny action was not configured.

Procedure

  1. The device will automatically reconfigure CPCAR values, and no action is required.

DEFD/6/HOSTCAR_DROP

Message

DEFD/6/HOSTCAR_DROP:Rate of packets to cpu exceeded the HOSTCAR limit. (CarID=[ULONG], ExceededPacketCount=[STRING])

Description

The rate of packets sent to the CPU exceeded the user-level rate limit.

Parameters

Parameter Name Parameter Meaning
CarID Indicates the bucket ID for rate limiting.
ExceededPacketCount Indicates the number of packets exceeding the user-level rate limit.

Possible Causes

The rate of packets sent to the CPU exceeded the user-level rate limit and the excessive packets were discarded.

Procedure

  • If a large number of normal service packets are sent to the CPU, run the cpu-defend host-car [ mac-address mac-address | car-id car-id ] pps pps-value command to adjust the rate limit. Otherwise, some packets will be discarded, affecting normal services. Adjusting the rate limit may affect CPU usage. You are advised to contact technical support personnel.
  • If a large number of packets from abnormal services are sent to the CPU, locate the cause based on other log information.

DEFD/3/IPC_FAIL

Message

DEFD/3/IPC_FAIL:IPC failed to send message to the slot [ULONG]. (MessageName=[STRING])

Description

The MPU failed to send IPC messages to an LPU.

Parameters

Parameter Name Parameter Meaning
[ULONG] Indicates the slot ID of the LPU.
[STRING] Indicates the message name.

Possible Causes

The LPU was abnormal.

Procedure

  1. Run the display device command to check whether the LPU has registered.

    • If so, go to step 3.
    • If not, go to step 2.

  2. If the LPU has not registered, IPC communication fails, which is normal. This log is informational only, and no action is required.
  3. Collect log information about IPC message sending failures of the LPU, and contact technical support personnel. You can collect diagnostic information using the display diagnostic-information command.
