To filter data by protocol
1 Select Properties➤Filter…
2 Specify the protocol(s) on which to filter traffic data.
You can limit the internetwork view to traffic values for a specified set of
protocols. The data report for each pair of end-to-end nodes will reflect
only the traffic that matches the protocol(s) you choose.
When you choose Properties➤Filter…, a window like the one shown in
figure 41 on page 198 appears. This window lets you choose the pro-
tocol(s) on which to filter. You may specify up to eight different protocols.
The protocol filter component window contains the following items.
Add to List Enter a protocol in this text field and press Return to add it to the filter
list. A protocol may be specified in one of three ways:
● As a protocol name (for example, ftp). When you enter a name, the
file sysprotolist and the built-in protocol map are searched. Any
entries that match the protocol name are placed in the filter list,
regardless of the protocol level.
● As a protocol level and name (for example, tcp ftp). When you enter
a protocol level and name, sysprotolist and the built-in protocol
map are searched; Any entries that matches both the protocol level
and name are placed in the filter list.
● As a protocol level and a numeric value that represents the protocol
you want (for example, tcp 21). If a matching entry is found in
sysprotolist or the built-in protocol map, its protocol name is
added to the protocol level and numeric value in the filter list; other-
wise, only the level and numeric value are added.
Protocol levels are the same as those used by Protocol Analyzer; refer to
table 38 on page 368 for a list of protocol levels.
