Ok - I think you guys have figured it out and have helped me understand
this better. By following your suggestions to model the device manually,
I got the message:

---

Error discovering the device at 172.19.222.221.

This device has responded to an ICMP ping request, but not to an SNMP
request.

Probable causes for SNMP failure:

*The device may not be responding to SNMP requests. If the device is
busy with network traffic, SNMP requests could be ignored.

*Timeout and Retry values could be too low. Increase and try again.

*Community name "public" may be incorrect. SNMP devices will not respond
to SNMP requests if the Community Name is not valid for the device.

*Check the device for Access Lists. If the device has an Access List,
your machine will have to be added to receive SNMP requests.

*For Site or Branch Manager versions of SPECTRUM, the total device
counter may be at maximum level.

The problem is that I am sending this as a trap but the device, a PC in
this case, doesn't have an SNMP listener on it. So, spectrum can't
contact it. I guess spectrum needs to do a handshake? Once I turned on
the listener, things work as desired. Thanks for your help!

Steve,

 

Couple of other things to check, in the order of most likely to least
likely:

 

Does the Community name Spectrum will use to contact the device match
what's on the device itself? In other words, it sounds like you have
Spectrum set up to accept any traps with the Community Name of 'public,'
but Spectrum will use a separate community name as defined in the Tools
-->Utilities -->Discovery --> New Discovery tool. There should be some
community names in there. Spectrum will try them in the order listed.

 

The next thing I'd check is that the device itself doesn't have an
access list that excludes the SpectroSERVER's IP address/Community Name.


 

Lastly, and least likely, I would recommend checking your Thread
Information (under the SpectroSERVER Control tab), to make sure that you
aren't maxed out on your Notification threads, and have some
Notification Latency, but since you can see the traps in the VNM, I
don't think that's a problem.

 

If none of those are the issue, then I'm stumped.

 

Cliff

Yes - I have the correct community name. I am using net-snmp to do the
tests. My test trap is:

snmptrap -v 1 -c public 172.19.222.121 1.3.6.1.4.1.1234 "" 6 1 ""
1.3.6.1.4.1.1234.1 s "test trap"

Steve,

 

I don't think you've missed anything; it should work.  I assume you've
already checked the SNMP Community name, to make sure that the devices
are sending what Spectrum is expecting.  I'm doing it here with three
different SNMP ports.  Works like a charm.

Hi - 

I have set up trap based continuous discovery and enabled unmanaged trap
handling but do not get any new devices when I send a trap from a new
device. I can see the traps coming in going to the VNM events, but I
thought trap based continuous discovery would automatically create a new
model under New Devices. Any hints? Is there some configuration I'm
missing?
