AP Application Visibility (AVC)

About this task

Controllers and service platforms can inspect every byte of each application header packet allowed to pass their managed radio devices. When an application is recognized and classified by the WiNG application recognition engine, administrator defined actions can be applied to that specific application.

Procedure

  1. Select the Statistics → System tab from the Web UI.
  2. 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.
  3. Select Application Visibility (AVC) from the menu.
    The Statistics → AP → Application Visibility (AVC) → Application screen displays.

  4. 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).
  5. 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.
  6. 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.
  7. Click the Category tab.
    Categories are existing system or user defined application groups (video, streaming, mobile, audio etc.) that assist administrators in filtering (allowing or denying) application data.
    The Statistics > Controller > Application Visibility > Category screen displays.

    Refer to the Top Categories graph to assess the most prolific, and allowed, application data categories utilized by the access point.
    Total Bytes Displays the top ten application categories in respect to total data bytes passing through the access point managed network. These are only the administrator allowed application categories approved for proliferation within the access point managed network.
    Bytes Uploaded Displays the top ten application categories in respect to total data bytes uploaded through the access point managed network. If this category data is not aligned with application utilization expectations, consider allowing or denying additional categories or adjusting their precedence (priority).
    Bytes Downloaded Displays the top ten application categories in respect to total data bytes downloaded from the access point managed network. If this category data is not aligned with application utilization expectations, consider allowing or denying additional categories and categories or adjusting their precedence (priority).
    Refer to the Category Detailed Stats table to assess specific application category data utilization:
    Category Name Lists the allowed category whose application data (in bytes) is passing through the access point managed network.
    Uploaded Displays the number of uploaded application category data (in bytes) passing the through the access point managed network.
    Downloaded Displays the number of downloaded application category data (in bytes) passing the through the access point managed network.
    Num Flows Lists the total number of application category data flows passing through access point connected clients. A category flow can consist of packets in a specific connection or media stream. Packets with the same source address/port and destination address/port are considered one flow.
  8. Click Clear Category Stats to clear the application category assessment data counters and begin a new assessment. Selecting this option will not clear application stats, just category stats.
  9. Click Refresh to update the statistics counters to their latest values.
