If you are looking for performance monitoring or fault reporting
/ isolation:
If your X.25 switch is SNMP compatible, there are a number of COTS
solutions available. All you'll need to do is add the MIB for the X.25
switch / X.25 equipped router to the monitoring system. HP Openview and
Cabletron Spectrum are both good solutions. HP scales better for very
large networks (very large is > 10,000 managed devices).
A lot of X.25 equipment pre-dates SNMP, however. If this is the case, you
may need to either write a translator that can map state change
notifications from the X.25 equipment into SNMP traps, and forward them to
the SNMP management system, and translate SNMP "puts" and "gets" from the
SNMP system into API calls for the X.25 equipment. If your X.25 equipment
does not have an API, things are even uglier. You may need to resort to
writing a translator that is SNMP on one side (to talk to the management
agent), and uses telnet commands and screen-scrubs (to talk to the switch)
on the other. This sucks. If you need to go this route, check out TCL /
EXPECT as a solution for automating telnet-based solutions.

If you happen to be using Alcatel X.25 equipment, check out the MasterX
suite from Network People at:
http://www.nwpeople.com/mda.htm
http://www.nwpeople.com/ma3_2.htm
This gets around the lack of SNMP/RMON support on older Alcatel equipment,
and saves you from having o write your own solution. If you're not using
Alcatel equipment, and don't have SNMP support on what you are using,
sorry, I've scarely touched X.25 in the past five years.
OTOH, if all you want to do is intercept and decode traffic, there's a
wide range of protocol analyzers and probes out there. The HP unit
mentioned by Bill works very well.
