Create a Custom Application Definition

About this task

Use the Application screen to create custom application definitions.

Extreme Network's AP5xx model APs, running WiNG 7.1.2 and later versions of the WiNG 7 OS, use Extreme Application Analytics (Purview™) libDPI engine to implement Application Visibility and Control (AVC) within a managed network. libDPI detects top-level hosting applications along with the services these applications host. Refer to the WiNG 7.2.1 CLI Reference guide for information on Purview Application policy and group.

Legacy WiNG 802.11ac APs and service platforms use a third-party DPI engine to enforce AVC within a managed network. To enforce AVC on legacy WiNG APs and service platforms, use application definitions in Create an Application Policy and Create an Application Group.

To create a user-defined application:

Procedure

Select Configuration → Network → Application.
The Application screen displays. This screen lists the application configurations defined thus far.

Refer to the following to determine whether a application requires creation, modification or deletion:


Name	Displays the name of each user-defined application created using this application interface.
Category	Lists the category to which each listed user-defined application belongs.
Application Description	Lists the 80 character maximum description administratively assigned to each listed user-defined application.

Select Add to create a new application configuration, Edit to modify the attributes of a selected application or Delete to remove obsolete applications from the list of those available.
If creating a new user-defined application type, assign it a Name up to 32 characters. Ensure you do not create confusion by naming a user-defined application with the same name as an existing application appearing the Application Policy screen.
Use the Category list to classify the application. Select the appropriate pre-defined category or select custom to create a custom classification for the application.
Provide an 80 character maximum Application Description to each new user-defined application to further differentiate it from existing applications.

Refer to the Application Definition field to assign either a network service alias, predefined URL list or set of HTTPS parameters to the user-defined application.


Network Service	Use the drop-down menu to select an existing network service alias for the user-defined application. If there are no existing network service alias suited to this new user-defined application, select the Create icon to define a new alias or the Edit icon to modify an existing one. Provide or modify a 32 character maximum name, along with a protocol type or number and source and destination port value. Up to four (4) service aliases can be supported.
URL List	defined application. URL lists are utilized for whitelisting and blacklisting Web application URLs from being launched and consuming bandwidth within the WiNG managed network. If no URL list suits this new user-defined application, select the Create icon to define a new list or the Edit icon to modify an existing URL list.
HTTPS	Select the + Add Row button to populate the table with configurable rows for HTTPS parameter type, attribute type, match criteria for the HTTPS server name and 64 character maximum server name attribute used in the HTTPS server message exchange.

Select OK to save the updates to the user-defined application configuration.

Select Reset to revert to the last saved configuration.
