Hi Paul,

  A couple of corrections:

1. The file name is "/usr/lnms/conf/FaultMan.conf"

2. Entries cannot be added to the file, therefore, you can't correlate
"everything and anything" - only those traps defined in the file.  The file
itself is self-documented.

3. We do filter on "generic" MIB-II traps, you are correct.  However, the
original question (and the Subject) is Cisco Traps.  We don't filter on
Enterprise specific traps unless they are defined in
/usr/lnms/conf/FaultMan.conf.

4. Rather than edit each entry in the file, you can use the command I
posted earlier:

/usr/lnms/bin/fault_correlator_filter off

  This will have the effect you are looking for.

Hope this clears up some confusion.  Ralph's description of the process is
accurate, however.  Optivity NMS moves trapd to port 412 and places a
process called "trap_server" on port 162.  Traps received on port 162 are
processed by trap_server and passed on to trapd when and where appropriate
as I have explained.
