NBAR Applications - Flow Details
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.
: The device running the Cisco NBAR engine must be configured to classify traffic before you run this report.
- . Application category detected by the Cisco NBAR identification engine. Others indicates bandwidth utilized by unclassified traffic.
- . Total number of bytes.
- . Average bit rate between two endpoints (browser and webserver, for example).
- . 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:
- . Fraction of total bandwidth capacity used. "N/A" denotes the measurement cannot be calculated because the bandwidth capability is unknown for the current interface.
