SNMP Proxy

[victor]

Hi!

There must be some difference between sites, but it's hard to tell anything based on provided information. Can you show full agent configs from both working and non-working sites, results of configuration polls of agent nodes, and screenshots of SNMP device configuration (both working and non-working)?

Best regards,
Victor

Hello,

and the attachemants.
SNMP device N9900112 is working with the agent.
SNMP device 192.168.10.10 is not working.
Both HP Procurve switches. 5308XL and 5406.

One question:
withe the configuration:
When i start configuration polling on 192.168.10.10, the netxms server is asking the agent "s-prtg-06" to do this, correct? Also querying snmp is started by s-prtg-06, also correct?
Is it needed to have a direct communication between the netxms server and the device 192.168.10.10?

Is there a log on the netxms server like the agent log? Maybe i can see there a failure?

Regards

Strange, I don't see much difference between configs. Server don't need direct communication with device if proxy agent is used. What configuration poll from console shows for 192.168.10.10?
You can enable server debug log as well, edit netxmsd.conf file and set LogFile parameter to some file, and DebugLevel parameter to 5 or 6. Seeing server log can really help.

Best regards,
Victor

Hello,

The server log is attached. Maybe you can find some helpful information?

Hi!

Looks like switch at 192.168.10.10 does not respond to SNMP requests. I would suggest to check SNMP configuration on the switch and firewalls in between, if you have any.

Hello,

i have tried the snmp test tool from paessler (http://www.paessler.com) on the windows system which is also netxms core server.
I can query snmp values (like uptime or interfaces).
This works...
Looks like an incompatibility between netxms snmp implementation and the hp device.
There is another switch with same problem. Other snmp devices are working.

Is there a way to start deeper troubleshooting?

Regards

[victor]

Hi!

It will be very helpful if you can capture packets from successful communication with snmp test tool and from unsuccessful communication with NetXMS server.

Best regards,
Victor

[MarcMoennikes]

Hello,

do you want capture with wireshark or something like that?
Can i send this to you directly?

Regards

[MarcMoennikes]

Hello,

found the problem.
The procurve switches have multiple ip adresses, because they are routing.
I have to use the switch ip which is in the same subnet as the agent.
When i query ip 192.168.10.10 from the agent and the switch replies with 172.31.0.1 netxms is not accepting the packets.
This seems to be different to most other snmp tools we use.

But now it works.

Thank you.

Regards
