display cpu-defend dynamic-car history-record

Function

The display cpu-defend dynamic-car history-record command displays historical records on dynamic adjustment of the default CIR value of protocol packets.

Default Level

1: Monitoring level

Usage Guidelines

After the default CIR value is set, you can run this command to view the historical records of adjusting the CPCAR value of protocol packets from 64 kbit/s to a specific value.

The granularity of each adjustment is 64 kbit/s on the switch. If the default CPCAR value is greater than 64 kbit/s, the adjustments from 64 kbit/s to the default CPCAR value are only recorded but do not take effect.

You can use this command to check a maximum of 100 latest historical records.

Example

# Display the historical records on dynamic adjustment of the default CIR value of protocol packets.

**Table 1** Description of the display cpu-defend dynamic-car history-record command output
Item	Description
Global status	The device is enabled to dynamically adjust the default CIR value of protocol packets. To enable the device to dynamically adjust the default CIR value of protocol packets, run the cpu-defend dynamic-car enable command.
Time	Timestamps of the default CIR value of protocol packets that is dynamically adjusted.
Protocol	Protocol name. To configure a protocol, run the cpu-defend dynamic-car [ arp \| vrrp ] command.
Packet-type	Packet type.
Slot	ID of the stack where the default CIR value is dynamically adjusted. The value indicates the slot ID if stacking is not configured.
CIR(Kbps)	Dynamically adjusted default CIR value, in kbit/s. If the default CIR value restores to the original default CIR value, NA is displayed. NOTE: When the rate of sending packets to the CPU is too large, the CPU becomes overloaded. The device restores the original default CIR value for protocol packets and this field is displayed as NA.
Status	Result of dynamic adjustment. The value can be: success: indicates that the adjustment succeeds. fail: indicates that the adjustment fails. conflict: indicates that the adjusted default CIR value conflicts the configured CIR value. The CIR value configured by users takes effect.
