4 Click the Define Filter button. Depending on the settings in the
Display Setup dialog box’s Packet Selection tab, the Sniffer either
marks all matching packets in the Decode tab (Select Packets >
Select Matching) or creates a new Decode tab with just the
filtered packets based on the network node and protocol selections
you made.
NOTE: For more information on the Packet Selection tab, see
Display Setup > Packet Selection Options on page 183.
Using the Matrix Map to Identify the Others Protocol Type
The traffic map's capacity to create a visual filter provides an ideal way
to investigate Others protocol types in the capture buffer. Others are
protocols that do not fall into the protocol categories predefined by
Sniffer Portable Professional.
To define a filter to select Other protocol packets to display in
the Packet Display window:
1 Select the Matrix tab on the bottom of the Packet Display window.
2 Uncheck all protocols listed in the traffic map except the Others
box.
3 Click the Define Filter button. Depending on the settings in the
Display Setup dialog box’s Packet Selection tab, the Sniffer either
marks all matching packets in the Decode tab (Select Packets >
Select Matching) or creates a new Decode tab with just the Other
packets.
NOTE: For more information on the Packet Selection tab, see
Display Setup > Packet Selection Options on page 183.
