Post-Analysis Views for Wireless Networks
When you display the contents of the capture buffer or a capture file, the
Sniffer software interprets and decodes the higher-level protocols within the
captured packets using its protocol interpreters.
You can display the decoded packets in a variety of formats. Each format
appears on a tab at the bottom of the Display window. In addition to the
standard information provided in each of these tabs, the Sniffer software adds
special 802.11 information to the following tabs, allowing you to concentrate
on statistics specifically for wireless stations:
 Matrix tab (see 802.11 View in the Post-Analysis Matrix Tab on page
121)
 Host Table tab (see 802.11 View in the Post-Analysis Host Table Tab
on page 123)
 Protocol Distribution tab (see 802.11 View in the Post-Analysis
Protocol Distribution Tab on page 125)
 Statistics Tab (see 802.11 Information in the Post-Analysis Statistics
Tab on page 127)
NOTE: The Matrix, Host Table, and Protocol Distribution tabs appear at the
bottom of the Display window only if the Post analysis tabs box is checked
on the General tab of the Display Setup dialog box.
NOTE: The post-analysis tabs described in this section all count various
802.11 frame types. The purposes of these frame types in an 802.11 network
are all described in the Dashboard Counters for Wireless Networks on page 101.
See that section if you have a question about a particular frame type.
802.11 View in the Post-Analysis Matrix Tab
The Matrix tab collects statistics for conversations between network nodes. In
addition to the standard MAC, IP, and IPX views present for all networks, the
Sniffer software provides an additional 802.11 view that allows you to
concentrate on information specifically for wireless stations.
NOTE: In this release, the Matrix view also includes an 802.11 view during
real-time monitoring.
