Getting Started Guide
FCS Errors - Shows the number of Frame Check Sum (FCS) errors detected. A high
number of FCS errors may indicate you are too far from the Access Point (low signal
strength), or the access point has too much traffic (need to add/move Access Points).
Total Captures - Show the total number captures in packets.
Undecryptable - Shows the number of packets which were encrypted with WEP/WPA
and were undecryptable possibly due to either incorrect WEP/WPA settings or different
access point than the one the analyzer is linked to.
- Press this button to restore the Capture settings to their default settings.
-This is the capture filter. You can filter on Management/Beacon, Control,
or Data Frames. Within Data Frames, you can select to view (or not view) Undecryptable
data frames.
-Starts packet capturing on data between the specified Source and Destination
devices. Press Stop Capture to terminate the capture. Leaving the Capture screen also
terminates the capture. Based on the devices selected in the Source and Destination list and
the filter selection (Management, Beacon, Control, and Data), frames are captured.
- Launches the packet viewer application on the current packet capture. If the
capture buffer is empty (no packet capture has been performed), the packet viewer will
display "Empty Capture." Within the packet viewer application, you may manually load
saved packet captures by pressing File | Open and pointing at the capture file (.CAP).
Packet captures are saved to the default directory C:\Program Files\Fluke
Networks\OptiView\Captures.
- Saves the capture file (filename.CAP) to the default directory C:\Program
Files\Fluke Networks\OptiView\Captures.
- Saves the Name table file (filename.NAM) to the default directory
C:\Program Files\Fluke Networks\OptiView\Captures. The Name table file contains names
associated with known hexadecimal representations. When you manually open a packet
capture file, you should also open the Name table file.
