• Average Rate (Last 1 Hour)—This bar graph provides summarized average rate per second
reporting for all VLANs specified in all VLAN traffic analysis tasks summarized by task. Each bar in
the graph is a link to more detailed reporting for the selected task. Each of these report types
includes several reports for the selected task:
{
Traffic—Reports include traffic trends that display the average inbound or outbound rate per
second, TopN by ToS, and the individual data samples for all VLANs for the selected task or for
a VLAN in a task.
{
Application—Reports include a table displaying percentage of application traffic generated by
all VLANs in a task and a graph displaying average rate of application traffic for all VLANs in
the selected task or for an individual VLAN in a task.
{
Source—Reports include a pie chart displaying the percentage of traffic generated by the TopN
source hosts and a table displaying volume and percentage of traffic generated for each of the
TopN source hosts for all VLANs in the selected task or for an individual VLAN in a task. The pie
chart is a link to more detailed reporting for the selected host.
{
Destination—Reports include a pie chart displaying the percentage of traffic generated by the
TopN destination hosts and a table displaying volume and percentage of traffic generated for
each of the TopN destination hosts for all VLANs in the selected task or for an individual VLAN
in a task. The contents of the pie chart link to more detailed reporting for the selected host.
{
Session—Reports include a pie chart displaying the percentage of traffic generated by the
TopN source and destination host pairs and a table displaying volume and percentage of traffic
generated for each of the TopN source and destination host pairs for all VLANs in the selected
task or for an individual VLAN in a task. The contents of the pie chart link to more detailed
reporting for the selected session.
• Traffic Trend and TopN Application for Selected Task (Last 1 Hour)—Provides per second average
traffic rate summarized by VLAN traffic analysis task for inbound or outbound traffic for all VLAN
for the selected task or for an individual VLAN in a task. A second set of pie charts reveals the
distribution of traffic for the TopN applications, with one chart for inbound traffic and one chart for
outbound traffic.
• Summary List (Last 1 Hour)—Provides per second traffic rate and the last hour traffic statistics
summarized by VLAN traffic analysis task for inbound or outbound traffic for all VLANs in all tasks.
VLAN traffic analysis configuration considerations
When you add a VLAN to a task, you must decide which VLAN belongs to each task. This determines
how NTA groups the VLANs for analysis, reporting, and navigation purposes. Viewing statistics in
juxtaposition to each other provides an additional layer of analysis and interpretation of data. You must
also consider the following:
• By default, NTA does not monitor any VLANs. You must create a task for every VLAN, or group of
VLANs, that you want to monitor and report on.
• You define how NTA groups VLANs for analysis and reporting purposes. NTA presents VLAN traffic
analysis tasks in the NTA left navigation system and provides summarized VLAN reporting based
on the way you have organized VLANs into tasks.
• You can add one or more VLANs from one or more devices into a single task. You are not limited
to adding VLANs from a single device into one task. IMC recommends adding one VLAN into only
one VLAN traffic analysis task to facilitate collecting traffic statistics.
• Add only VLANs for which you want to view statistics. Do not add all of the VLANs on a device
unless you want to view reporting for all VLANs.
