Postcapture Matrix Tab
202 Sniffer Portable Professional
The Matrix tab collects statistics for conversations between network
nodes. For LANs, the matrix tab accumulates MAC, IP network, IP
application, IPX network, and IPX transport-layer information. Sniffer
Portable Professional also provides an additional 802.11 view for
wireless LANs that allows you to concentrate on information specifically
for wireless stations.
You can view accumulated data as a traffic map, as a table, or as a bar
or pie chart.
The traffic map provides a birds-eye view of network traffic
patterns between nodes. You can filter out unwanted traffic by
unchecking certain protocols, or by selecting specific network
nodes to display.
The matrix tables display traffic count statistics for node pairs:
The outline table provides a quick summary of total bytes and
packets transmitted between pairs of network nodes.
The detail table provides a quick summary of the higher layer
protocol type and its traffic load transmitted in and out of each
conversation node pair.
You can sort a matrix table by clicking a column heading (for
example, to sort the statistics by packets, click the Packets
column heading). Click a second time to sort in reverse order.
The bar chart displays the top 10 busiest conversation node pairs.
The pie chart displays the top 10 busiest conversation node pairs
as relative percentages of the total load of traffic.
In all views, you can display conversation traffic at the link layer, MAC
layer, or selectively view only the IP or IPX layers.
In the table views, you can export the statistics for tabulation or
charting.
