IBM Director is supposed to use the Trap Service. It was for them that we made the switch to the Trap Service ourselves, back when they first came out. James Shanks Level 3 Support for Tivoli NetView for UNIX and Windows Tivoli Software / IBM Software Group
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. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Johanna Hislop | Software Development | IBM Tivoli Storage Area Network Manager | 507-253-7647 | jhislop@us.ibm.com James Shanks/Raleigh/IB M@IBMUS To Sent by: nv-l@lists.us.ibm.com owner-nv-l@lists. cc us.ibm.com Subject Re: [nv-l] Disabling port 162 use 04/29/2004 04:06 PM Please respond to nv-l 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?

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? ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Johanna Hislop | Software Development | IBM Tivoli Storage Area Network Manager | 507-253-7647 | jhislop@us.ibm.com James Shanks/Raleigh/IB M@IBMUS To Sent by: nv-l@lists.us.ibm.com owner-nv-l@lists. cc us.ibm.com Subject Re: [nv-l] Disabling port 162 use 04/29/2004 12:33 PM Please respond to nv-l 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?
