Top N ToS Report

A 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.

To display a Top N ToS report, start from an interface 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 from the report type menu at the top-left corner of the page.
3. Make sure that 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 by default. The report includes views for inbound, outbound, and total ToS data.

4. (Optional) Change the data presentation type and the data measurement type 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 with respect to 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.
