application

Global Configuration Commands

Creates an application definition and enters its configuration mode. Use this command to create application detection signatures that are not in the pre-defined set of application definitions provided by ExtremeWireless WiNG.

Application Visibility and Control (AVC) enables detection of top-level hosting applications along with the services these applications host. It also provides Metadata extraction capabilities for a variety of protocols and applications.

AVC and statistics reporting is available on both the WiNG 5.9.X and WiNG 7.X operating systems. However, the DPI engine used to check data points varies. The WiNG 7.X OS uses Extreme Application Analytics (Purview™) libDPI engine to detect applications and manage traffic flow. It recognizes 36 application categories with 2458 applications. The WiNG 5.9.X operating system uses a third-party DPI engine, which recognizes 23 application-categories with a total of 2384 applications.

The application command is part of the AVC feature. It allows you to create custom application definitions to detect native applications. Refer to the following on how to use the customized application definitions:

• For WiNG 5.9.X networks, configure the application definition on the controller and apply in the following contexts.
  • application-policy - To enable packet filtering on WiNG 5.9.X APs, use the application definition in the 'application policy' and specify allow, deny, mark and rate-limit rules for these application packets.
  • application-group - To enable mandatory stats reporting on WiNG 5.9.X APs, use the application definition in an 'application group'.
• For WiNG 7.X networks, configure the application definition on the controller and apply in the following contexts:
  • purview-application-policy - To enable packet filtering on WiNG 7.X APs, use the application definition in the 'purview application policy' and specify allow, deny, mark, and rate-limit rules for these application packets .
  • purview-application-group - To enable packet filtering on WiNG 7.X APs, use the custom application definition in the 'purview application group'.

Note

The WiNG 7.X OS does not support Purview™ libDPI engine on NX5500, NX7500, NX9500, NX9600 and VX9000 platforms. This support will be introduced in future releases.

Supported on the following platforms:
