NBAR Applications - Flow Details report reveals top n applications ranked by bandwidth usage for the selected interval. Applications reported are detected and classified by a network based application recognition engine (NBAR) across interfaces associated with a device or group. This report is useful for identifying application traffic that uses randomly allocated rather than "dedicated" logical ports.

Note: The device running the Cisco NBAR engine must be configured to classify traffic before you run this report.

Understand column data

The default view of each report contains a grid with the following columns:

  • Application. Application category detected by the Cisco NBAR identification engine. Others indicates bandwidth utilized by unclassified traffic.
  • Bytes. Total number of bytes.
  • Bit Rate. Average bit rate between two endpoints (browser and webserver, for example).
  • Byte Percentage. Percentage of total traffic associated with each detected application.

To display Flow and Packet measurements, click a column heading ( ) for column selection list ( ). You can also include:

    • Utilization. Fraction of total bandwidth capacity used. "N/A" denotes the measurement cannot be calculated because the bandwidth capability is unknown for the current interface.
