Top Interfaces by Traffic

Top Interfaces by Traffic report reveals a ranked list of network interfaces with the most traffic for the selected interval. This is a useful tool for analyzing traffic symmetry.

Tip: Use Report Settings () to display a graph that displays a side-by-side comparison of incoming and outgoing traffic volume.

Note: The same bytes can be counted twice where a byte total is noted arriving from a sender and the same bytes are counted when relayed to the receiver.

Interface. Device hostname, IP address, or custom label.
Incoming Bytes. Traffic volume received on the interface.
Incoming Rate. Total average rate of inbound traffic.
Incoming 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.
Outgoing Bytes. Total bytes transmitted from the interface.
Outgoing Rate. Total average rate of outbound traffic.
Outgoing Utilization. Fraction of bandwidth capacity used.

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

Source Name. Device hostname, IP address, or custom label.
Interface Name. Textual name of the interface (ifName).
SNMP Index. Network interface SNMP table identifier (ifIndex).
In Speed. Inbound hardware speed.
Out Speed. Outbound hardware speed.

Tip: Interfaces with an index of 0 denote the NULL interface.

Control	Description
Device.	Browse and choose a networking device that is a Network Traffic Analysis monitoring source.
Network Interface.	Choose a single physical or virtual interface Network Traffic Analysis you want traffic statistics for. Choose direction of traffic over the network interface (Inbound, Outbound, Inbound and Outbound, or Bounce for invalid traffic.).

Control	Purpose
Date Range	Choose or define an overall date range.
Business hours	Focus on specific days of the week and periods within each day. Reveal trends that are sensitive to business hours, time zones, and other periodic attributes in the observed data.

Control	Purpose
Columns.	Click a check box to display the column. Clear the check box to hide it.
Move Column.	Click on a column heading and drag it to reorder your table's columns.
Advanced Filtering.	Apply category, pattern, and keyword filtering to column data.

Control	Purpose
Show Top n Items	Limit items to the samples with the highest values.
Sort by Field	Select a column to sort by (if applicable).

Control	Purpose
View Options	Select/clear the checkboxes to display/hide Totals. Display totals for each column. Others. Remainder values that do not make the top n. Chart. Display the selected Chart Type. Legend. Include legend and grid lines for readability. Trend Lines. Present data a smoothed average to show trend.
Chart Type	Select a chart type and associated options: Pie. Pie distribution chart. Line/Area. Scatter graph that connects adjacent measurements with straight lines. Spline/Area Spline. Choose a graph with a smoothed appearance where adjacent samples exhibit a gradual slope. Vertical Bar/Horizontal Bar. Vertical or horizontal bar chart/histogram. Note: The magnitudes of incoming and outgoing bandwidth utilization per interface are summed when presented in plotted graphs and charted distributions .
Y-Axis Scale	Scale Y-axis (chart and graph height) automatically or choose a fixed size.
