More about the Matrix Traffic Map
204 Sniffer Portable Professional
The traffic map in the postcapture Matrix tab is a powerful tool that gives
you a birds-eye view of the network traffic patterns captured in the
packet buffer. It gives a complete graphical presentation of the traffic
pattern between network nodes, as well as the type of protocol used for
communications.
To view the traffic map from the Packet Display:
1 Select the Matrix tab on the bottom of the postcapture Display
window. If you do not see the Matrix tab, make sure that the
Show Post Analysis tabs option in the Display Setup dialog
box’s General tab is enabled.
2 Click the traffic map button. A traffic map showing conversation
load and protocol type is displayed.
To view traffic at a different layer:
1 Open the drop-down list on the upper left corner of the traffic map.
Select the layer at which you want to view traffic (for example, IP or
IPX). A traffic map showing conversation load and protocol type at the
selected layer is displayed.
Using a Visual Filter in the Traffic Map
The traffic map can be used to automatically define a filter. You can
select stations and particular protocols that displayed on the traffic map
and Sniffer Portable Professional will automatically configure a filter to
match your selections.
To use the Traffic Map to define a filter:
1 Select the Matrix tab on the bottom of the postcapture Display
window. If you do not see the Matrix tab, make sure that the
Show Post Analysis tabs option in the Display Setup dialog
box’s General tab is enabled.
2 On the pull-down window, select the protocol suite. In the left
column, select one or more sub-protocols to display.
3 Highlight any network node(s) you want to filter for. To select more
than one node, hold the Ctrl key down while you click additional
nodes.
