Port-Based User-Defined Applications

When an application is unrecognized and generically (or incorrectly) categorized you can configure an application identification policy by IP port and protocol.

Wireless traffic that matches a configured policy will be displayed using the policy description text in the Application Overview donut charts. You can create new port-to-application name mappings individually using the Security > Traffic Flow ACL > Port based User Defined Application tab.

This type of application categorization is the least granular in configuration and therefore it has the lowest priority as a means of application identification. For example, if you configure a port-based user-defined application for port 80/TCP, any such matching wireless traffic not identified by either an IP-based application or the default embedded applications will be identified as belonging to this application.

Application Port Mapping

The following figure shows how a port-based user-defined application policy could be used to identify all port 8081 wireless traffic as "HTTP Proxy" traffic and display this name in application recognition pie charts and tables.

Complete the following steps to create a port-based user-defined application.

  1. Navigate to Security > Traffic Flow ACL > Port Based User Defined Applications.
  2. Click Add > Port Based User Defined Applications.
  3. In the Add sidebar, enter the following:
    • Application Name: Enter an application name. You can enter up to 32 characters.
    • Port: Enter a port number or port range.
    • Protocol: Select a protocol (TCP or UDP) from the drop-down list.
  4. Click Add to add the application.
