P2P behavior identification rules are another type of application identification and are used for the intelligent identification of P2P data that cannot be recognized in the Application Signature. P2P behavior rules can be edited. Click P2P Behavior, and the rule editing dialog box will be shown.

Select Enabled to enable this rule.

Name: specifies the name of the intelligent identification rule.

Category: specifies the application type to which the rule belongs.

Description: specifies the description of the rule.

The preceding three fields cannot be edited.

In Sensitivity, you can set the sensitivity of the rule to high, medium, low, and very low. Errors may exist in the intelligent identification of P2P applications. Therefore, you can set the sensitivity to improve the identification accuracy. You can adjust the sensitivity level based on the data identification conditions. For example, suppose there is a large amount of unrecognized data. In that case, the connected ports are all random high-end ports, and the destination IP addresses are unknown. The data may be unrecognized P2P data. In this case, you can set the sensitivity to a high level. On the other hand, if some application data is mistakenly recognized as P2P data, it may be because the sensitivity level is too high. To solve this problem, adjust the sensitivity to a lower level.

In Excluded Port, set one or more ports to be excluded from scanning. If the destination port of data is an exclusion port, the device will not perform P2P identification for the data.
