View Application Visibility - AP Application Stats

About this task

Legacy WiNG APs, running WiNG 7.2.1 OS, use a third-party DPI engine to inspect every byte of each application header packet allowed to pass their radios. When an application is recognized and classified by the DPI engine, administrator-defined actions are be applied to that specific application. This screen displays statistical data related to the type and volume of application traffic handled by the AP.

Note

Extreme Network's AP5xx model APs, running WiNG 7.1.2 and later versions of the WiNG 7 OS, use Purview™ libDPI engine to implement Application Visibility and Control (AVC). libDPI detects top-level hosting applications along with the services these applications host. Once detected, administrator-defined rules are applied that dictate how each traffic type is managed within the network. These rules are enforced through a Purview Application Policy. Refer to the WiNG 7.2.1 CLI reference guide for more information.

Procedure

Select the Statistics → System tab from the Web UI.
Expand an RF Domain node, and select one of it's connected access points.
The Access Point's statistics menu displays in the right-hand side of the screen, with the Health tab selected by default.
Select Application Visibility (AVC) from the menu.
The Statistics → AP → Application Visibility (AVC) → Application screen displays.

Refer to the Top Applications graph to assess the most prolific, and allowed, application data passing through the controller/access point managed network.


Total Bytes	Displays the top ten utilized applications in respect to total data bytes passing through the access point managed network. These are only the administrator allowed applications approved for proliferation within the access point managed network.
Bytes Uploaded	Displays the top ten applications in respect to total data bytes uploaded through the access point managed network. If this application data is not aligned with application utilization expectations, consider allowing or denying additional applications and categories or adjusting their precedence (priority).
Bytes Downloaded	Displays the top ten applications in respect to total data bytes downloaded from the access point managed network. If this application data is not aligned with application utilization expectations, consider allowing or denying additional applications and categories or adjusting their precedence (priority).

Refer to the Application Detailed Stats table to assess specific application data utilization:


Application Name	Lists the allowed application name whose data (bytes) are passing through the access point managed network.
Uploaded	Displays the number of uploaded application data (in bytes) passing the through the access point managed network.
Downloaded	Displays the number of downloaded application data (in bytes) passing the through the access point managed network.
Num Flows	Lists the total number of application data flows passing through the access point for each listed application. An application flow can consist of packets in a specific connection or media stream. Application packets with the same source address/port and destination address/port are considered one flow.

Click Clear Application Stats to clear the application assessment data counters and begin a new assessment. Selecting this option will not clear category stats, just application stats.
