Top N ToS Report

The Top N ToS report provides information about the Types of Service (ToS) markings of the packets that generate the most traffic for the selected interface. This topic describes how to display a Top N ToS report.

Follow these steps:

1. Display an interface report in either of the following ways:
   • Locate and click an interface on the Interfaces page.
   • Click an interface link in an existing view--for example, on the Enterprise Overview page.
2. Select ToS as the report type at the top of the page.
3. Make sure the report scope is set to Top N ToS. The Top N ToS link should appear next to the report type setting.

   The report page is updated to show ToS data in stacked trend charts. The report includes views for inbound, outbound, and total ToS data.

4. (Optional) Change the type of data presentation and measurement by using the Presentation options.
   • Stacked Trend Chart of Rate, Volume, or Utilization data (Default setting)
   • Trend Chart of Rate, Volume, or Utilization data: Use the Show Top setting to specify the maximum number of conversations to include.
   • Pie Chart
   • Summary Table of Rate, Volume, or Utilization data

   Each option displays data that is inbound and outbound on the selected interface.

5. (Optional) Change the reporting period: Open the Timeframe dialog by clicking the timeframe link.

   The reporting period is the most recent 24-hour period by default.
