logging
  
    
      purview-application-policy
      Enables DPI application recognition logging. It also sets the logging
        level.
      DPI analyzes packet and packet content headers to determine the nature of network traffic.
        When enabled, the Purview™ DPI engine inspects layer 7 traffic to identify applications
        (such as, Netflix, Twitter, Facebook, etc.) and extract metadata (such as, host name, server
        name, TCP-RTT, etc.) for further use by the WiNG firewall.
    
    Supported in the following
        platforms:
      
      
        - Access Points — AP410i/e, AP460i/e,
          AP505i, AP510i/e, AP560i/h
