NBAR Applications - Interface Totals
NBAR Applications - Interface Totals report reveals the top n NBAR-classified traffic categories observed at the network interface for the selected interval.
- . Application category detected by the Cisco NBAR identification engine.
- . Total number of bytes.
- . Average number of application bits transferred between two endpoints (browser and webserver, for example).
- . Percentage of overall traffic.
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.
