Verifying the CPU Attack Defense Configuration

Verifying the CPU Attack Defense Configuration

Procedure

  • Run the display cpu-defend policy [ policy-name ] command to check the attack defense policy.
  • Run the display cpu-defend statistics [ packet-type packet-type ] [ all | slot slot-id ] command to check statistics on packets sent to the CPU.

    NOTE:

    Only the S5720EI, S5720HI, S6720S-EI, and S6720EI support this command.

  • Run the display cpu-defend applied [ packet-type packet-type ] { mcu | slot slot-id | all } command to check the actual CIR values after protocol packets are sent to the chip.
  • Run the display cpu-defend rate [ packet-type packet-type ] [ all | slot slot-id ] command to check the rate limit of protocol packets sent to the CPU.

    NOTE:

    Only the S5720EI, S5720HI, S6720S-EI, and S6720EI support this command.

  • Run the display cpu-defend configuration [ packet-type packet-type ] [ all | slot slot-id ] command or display cpu-defend configuration [ packet-type packet-type ] { all | slot slot-id | mcu } command to check the CAR configuration for protocol packets sent to the CPU.
  • Run the display cpu-defend dynamic-car history-record command to check history records on dynamic adjustment of the default CIR value of protocol packets.

    NOTE:

    Only the S5720HI, S5720EI, S5720SI, S5720S-SI, S5730SI, S5730S-EI, S6720LI, S6720S-LI, S6720SI, S6720S-SI, S6720S-EI, and S6720EI support this command.
