Hello,

I am running SCOM 2012 R2 and I have had SNMP traps enabled for a long time now.  I have only been monitoring my switches, but now I want to monitor other devices such as UPS's and printers.  I followed the article "How the heck do I get it working?" and I have no issues receiving traps from my switches.  But my printer, a Lexmark E260DN sends traps to my P.C. and I am using a free SNMP trap receiver.  It sends the traps to my SCOM server too, using the same app.  But SCOM does not display them.  My UPS, an APC Smart-UPS 5000, is only discovered using ICMP.  I tried discovering it using SNMPV1 and SNMPv3.  Both versions result in the same way.  I get "No Response SNMP".  It is definately not a firewall issue.  I have 35 other devices that are sending me traps.  34 of them are switches and the other one is the printer I just discovered.  Any help would be appreciated.

Hi,

Did you follow the article below to discover your device:

You may first remove those discovered printers first, and then re-discover them and check the result. Please also check operation manager event logs for more information to help troubleshooting.

Hello,

I did discover my devices using this method.  I dont think it's a discovery issue.  The server can discover the devices.  It's just that it does not receive traps from one of them and the other new device comes up with "No Response SNMP".

Hi,

You may check Network Discovery Progress Events found in the Monitoring space under Operations Manager\Network Discovery\Network Discovery Progress Events.  Network Tracing may help also.

In addition, please refer to the article below to troubleshoot network device discovery issues:

Hello,

I did allow MonitoringHost.exe and PING.exe in the FW.  I ran the discovery again and I still get "No Response SNMP".

Hello,

It is working now.  I guess I needed to delete the devices, and re-discover them after configuring the firewall.  Thank you for your help.
