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 — AP505i, AP510i/e,
AP560i/h
Note
Purview DPI engine is not supported on
the WiNG 7.1.2 enabled NX5500, NX7500, NX9500, NX9600 and VX9000 platforms. This support
will be introduced in future releases.
