Re: [nv-l] Confused about setting up an SNMP proxy

[James Shanks <jshanks@us.ibm.com>]

I find your confusion even more puzzling than you do.

(1)  Your NetView for Windows (from your description I assume that's what you are on) does not care what community string is in the trap.  It will receive log and display them all.  You can filter them out of your event browser view if you want, but that's all.   

(2)  A proxy is not usually needed.  If the device is SNMP-capable and can send it's own traps, you just configure them to send them to the address of your NetView box.  If these things are not SNMP-capable, then how would you even get their proprietary traps to the proxy?  Perhaps you should explain in some more detail just what kinds of devices you are talking about.

(3)  By default the NetView for Windows TEC adapter will only send NetView traps to TEC.  To change that you have to modify the config files which control it.  They are in \usr\ov\conf and are named tecad_nv6k.xxx.  You have to modify the OID file to tell the adapter what to collect, the CDS file to map what is collected into a TEC event, and the CONF file to tell the adapter which entries in the CDS you want to use at this particular time.  My advice is to obtain the Event Adapters Guide that ships with your version of TEC and read about adapters in general and how t configure these files.  The NetView for Windows adapter is a port of the OpenView adapter for UNIX which ships with TEC, so read about how it works and you'll have an understanding of how the Windows adapter works.

The only way you can filter which devices can send you events to send to TEC would be to create a smartset which contains them.  The Windows adapter allows filtering by smartset after all the other selection is done.   This is described in the NetView  documentation.

Hope this helps

Greetings all,
 
My knowledge of setting up Netview for SNMP traps is quite fuzzy and I need some clarification.
 
I want to setup Netview to receive SNMP traps from several vendors' MIBs and forward them on to TEC. 
 
I have:

• Added the traps to the trap engine from the MIB
• Built the appropriate BAROC for the MIB
  Now I am a bit confused. For starters I want to create a different community string so that I can get only these traps and not the flotsam of SNMP traffic running across my network. Furthermore, I am thinking I need to setup an SNMP proxy since these machines are non-network devices (not switches or hubs or routers).
   
  I am confused about the next steps to take. Can someone provide me some pointers?
   
  Thanks in Advance,
