Application Visibility

With the ability to gather application analytics, you can engineer wireless traffic to support company policies, preserve bandwidth, identify critical applications, assign higher priority and QOS values, and enhance network security. Application Visibility and Application Enforcement makes it possible to block restricted web content and block or limit peer-to-peer protocols to preserve network bandwidth.

With ExtremeWireless, you can view the top 5 application groups by WLAN (Wireless Local Area Network) from the controller Home dashboard and the top 5 application groups for each client from the Client Details report.

The Applications by WLAN pie chart displays the top 5 application groups running on that WLAN. ExtremeWireless cycles through the active WLAN Services displaying statistics. To view detailed statistics, enable Application Visibility during the WLAN configuration; then, on the Home dashboard, click the displayed pie chart under Applications by WLAN. Or, click Enable Application Visibility from the Home dashboard.

The controller and AP capture statistics for 31 pre-selected application groups. The top 5 application groups are displayed based on bytes and throughput over the last two-minute measuring period. The stats for each WLAN display for 30 seconds on a continuous cycle. Historical statistical data is available from ExtremeCloud™ and Extreme Application Analytics™.

To manage wireless traffic in support of company policies, define Layer 7 filter rules from the Filter Rule Definition dialog. Layer 7 represents the application layer of the OSI communication module. Define policy rules with access control actions for specific applications or groups of applications. Application visibility supports standard Extreme Application Analytics™ signatures. You can also configure up to 64 extended web application signatures.

Note

For application enforcement, you must enable Application Visibility in WLAN configuration.
