Local Traffic Policies Policy List

There are two types of policies shown: 1. [Virtual Server Name] 2. asm_auto_l7_policy_[Virtual Server Name]

 

What is the difference between them?

 

One thing I noted whether you create a policy and assing VS to it or directly assign the VS at the time of creation the asm_auto_l7_policy_[Virtaul Server Name] automatically created.
