Wireless Frame Capture
This chapter shows you how to configure and use wireless frame capture on the ZyWALL / USG.
9.1 Wireless Frame Capture Overview
Troubleshooting wireless LAN issues has always been a challenge. Wireless sniffer tools like
Ethereal can help capture and decode packets of information, which can then be analyzed for
debugging. It works well for local data traffic, but if your devices are spaced increasingly farther
away then it often becomes correspondingly difficult to attempt remote debugging. Complicated
wireless packet collection is arguably an arduous and perplexing process. The wireless frame
capture feature in the ZyWALL / USG can help.
This chapter describes the wireless frame capture commands, which allows a network administrator
to capture wireless traffic information and download it to an Ethereal/Tcpdump compatible format
packet file for analysis.
9.2 Wireless Frame Capture Commands
The following table identifies the values required for many of these commands. Other input values
are discussed with the corresponding commands.
