Whether the bearer protocols of a predefined application used as a match condition and referenced by a policy shall also be referenced by the policy

Yes. If a predefined application is referenced in a policy as a match condition and the predefined application has a bearer protocol, the bearer protocol must also be referenced in the policy. For example, BT is referenced in a policy as a match condition, the policy must also reference its bearer protocol HTTP. For application and bearer protocol information, see http://sec.huawei.com. When you download the SA signature database, you can download the signature database description file to understand the relationship between the application and bearer protocol.
