Well, the issue with just using NetView's trapforwarding is that we're
dealing with SNMP v2 traps in some situations. The other application is
IBM Director. I follow what you're saying, but am not sure about IBM
Director's capabilities. I'm kind of in the middle of it, as I see NetView
is too. I'll take this info back and see if this helps the people working
on this issue.

In order to use the Trap Service, you have to be written to use one of the
Microsoft APIs for the Trap Service, such as SnmpMgrGetTrap. That's the
lowest level API. There are more sophisticated ones to get SNMP V2 traps.
If you aren't written to do this, but expect to listen on port 162/udp
directly, then only one application on the box can get traps, and it in
turn must forward to all the other trap receivers, else they get nothing.
I don't understand exactly what "The system being set up wants an
application other than ITSANM/NetView to be picking up the SNMP traps from
port 162." means. I think you are saying that you have some other
application that you want to put on the box and also get traps. Well, it
has to be coded to use the Trap Service for this to be simple. It is
isn't, then you will have trouble making the these apps co-exist.
If the other app can use another port, then trapfrwd in NetView can be
coded to send traps to that port on the same box. If it can't, and it has
to own 162/udp, then the question is, can it forward what it receives to
another port on the same box? If not, then you are out of luck.
Do you follow this? What application are we talking about? Can you ask
its vendor about its capabilities?

Thanks for the info. I should have known that it was the trap service
using it. The system being set up wants an application other than
ITSANM/NetView to be picking up the SNMP traps from port 162. Should both
applications be able to get the traps from the MS Trap Service without
having to make a choice over which application gets it and then has to
forward it to another application or have that application just go without?

Actually, it isn't. Not by default any way. The Microsoft Trap Service is.
And NetView's trapd uses an API to get traps from the Service. Any other
well-behaved MS app can do the same thing. NetView started using the Trap
Service back in Version 6, so that other apps could be installed on the
same Windows box and get traps too. So normally there is no good reason to
alter that.
But if you must, you can make him stop using the MS Trap Service and then
listen on any other port you choose by editing the Registry.
And this isn't recommended though possible.
Is this really what you want to do? Why?

How can I set up NetView 7.3 for Windows to not listen on port 162?
Thanks
