The behavior of each rule is different, and so are their configuration parameters. But the designed principle of each rule is the same.

The configuration is divided into three parts as

part according to your requirement. As for the definitions of the three-part configuration, please refer to the following description.

1. Status: Describe the status and name of this rule.

2. Condition: What kind of characteristics does packet hold? And it will be captured by this rule.

3. Action: If the packet is captured by this rule? What action will this rule do?
