Abnormal Packet Analysis

Function

The anomaly packet analysis chart displays the traffic status of normal and anomaly DNS request packets.

Parameter

**Table 1** Query parameters of Abnormal Packet Analysis
Parameter	Description
Device	Select a device from the drop-down list. Total-Cleaning and Total-Detecting are described as follows: Total-Cleaning: Indicates that DNS traffic on all cleaning devices is queried. Total-Detecting: If two or more detecting devices in a defense group work in Load Redundancy mode, the maximum DNS traffic volume in the defense group is queried and the sum of DNS traffic volumes among defense groups is queried. If two or more detecting devices in each defense group work in Load Balancing mode, the sum of DNS traffic volumes within each defense group and among defense groups is queried.
Zone	Click , select a Zone on the Zone page that is displayed, and then click OK.
IP address	Enter the destination IP address. Both IPv4 and IPv6 addresses are applicable. The DNS traffic destined for the IP address is queried.
Time	Click to select the start time and end time of statistics. Or you can change the time values in corresponding text boxes. The end time should be later than the start time and the interval cannot be longer than one year. If the query interval is longer than or equal to seven days and shorter than one year, statistics are collected daily. If the query interval is longer than or equal to one day and shorter than seven days, statistics are collected hourly. If the query interval is shorter than one day, statistics are collected every five minutes.

Example

If the Device is set to Total-Cleaning and the Zone to Total, the analysis of the normal and anomaly packets within a period of time is displayed in Figure 1.
