In addition to off-line or post-capture analysis, you can display protocol
decodes in real-time as packets arrive. You do not have to stop a capture
session to see protocol decodes.
Real-time decodes are disabled by default. After launching Sniffer
Portable Professional, enable real-time decodes and set real-time
decode options.

Enabling and Setting Real-time Decodes
In addition to off-line or post-capture analysis, you can display protocol
decodes in real-time as packets arrive. You do not have to stop a capture
session to see protocol decodes. Real-time decodes are disabled by
default when Sniffer Portable Professional is installed. Setting Real-time
decode options includes specifying the refresh rate used in Live-Scroll
mode.
To enable real-time decodes:
1 From the Tools menu, select Options, then click the Real-Time
tab.
2 Select the Real Time Decode option.
3 Specify a refresh rate in the field provided. This rate is used in
Live-Scroll Mode to jump to the new set of latest packets to decode
at each defined interval. You can specify a rate between 1 and 60
seconds.
See Scrolling Modes in Real-time Decodes on page 215 for detailed
information.
