In Non-live scroll mode the Decode window does not automatically
update. To view new packets, you have to manually scroll the Summary
pane using the scrolling tools to the right of the pane.
In either Live or Non-live scroll mode, the Detail and Hex panes show
the first packet by default when the Real-Time Decode window opens.
When you select a new packet in the Summary pane, the Detail and Hex
panes are refreshed to display information specific to the selected
packet.
To switch between Real-time Decode scrolling modes:
1 Ensure Real-time Decode is enabled. See Enabling and Setting
Real-time Decodes on page 213.
2 Start a capture session. This opens the Real-Time Decode window
automatically.
3 Switch from Live to Non-live scrolling in the Real-Time Decode
window by clicking any summary line in the Summary pane, or
moving the Summary pane scroll bar upward. You can do this at
any time.
4 You can also switch from Non-live to Live scrolling using Ctrl +
End, or clicking Start scrolling and Stop scrolling . You
can do this at any time.
Real-time Decode Display Limitations
When specifying Real-time decode options or viewing real-time decodes,
please note the following:
Capture to disk is not supported with Real-time decodes. If you
have Capture to Disk selected as a capture option, the Real-Time
Decode window is disabled.
The Real-Time Decode window displays the Frame Number, Status,
Source Address, Destination Address, Summary, Length, Delta
Time, and Absolute Time columns, but these statistics are not
user-configurable.
Display setup items are not user-configurable in the Real-Time
Decode window. The Real-Time Decode window will always display
Show Network Address, the Display Vendor ID on the MAC address,
and the Summary line for the last protocol layer.
The Real-Time Decode window does not display Expert Symptoms,
Two-Station Format, nor will the Window resolve the network name
using the Address book.
