sFlowTrend-Pro comes with a built-in mapping from protocol numbers (eg TCP and UDP port) to names, to make charts and reports easier to understand. If you have any site-specific protocols that you would like to add, so that they show with the correct name for your network, then this can achieved by adding a protocol definitions file.
First, create a file called
in the sFlowTrend-Pro server home directory (you can find this from
menu, General tab, File location).
Make sure that you create the file on the server running the
sFlowTrend-Pro service. Then add to the file the
definitions required. The format of the file must be
[Section] number, name number, name rangeStart-rangeEnd, name number, name, longName ... [Section] number, name number, name ...
[Section] provides definitions for a
specific type of protocol number. The sections that are currently
allowed are show in Table 15.1, “Protocol definition sections”.
Following the section definition, any number of definition lines
can be entered. The definition lines start with the protocol
number (in decimal), or optionally a range of numbers, followed
by a comma then the name of the protocol. This can be optionally
followed by an extended name, which is currently not used in
sFlowTrend-Pro, but could be in the future.
Table 15.1, “Protocol definition sections” shows the sections than can be used, and provides an example of a definition line that might be in each section. Once you have created the file with the definitions that you require, or if you edit the file, the sFlowTrend-Pro service must be restarted for the change to take effect.
