SNMP ERROR

jmini · Post by **jmini** » Thu Jan 12, 2006 10:43 am

Hello,

I have problems with getting data from device called ethernetbox by pcmeasure.com. I have added a new host but there is displayed SNMP ERROR.

I have contacted the vendor and he told me that I have to disable SNMP system information, like uptime and systemlocation. I know that it was possibe in mrtg to use noMib2=yes. I think a lot of you know mrtg

My question is how can I do the same in cacti?
My System: SLE 9 for itanium, cacti 0.8.6.f

Thank you in advance

Joerg

Change the Downed Host Detection in Cacti settings -> poller from SNMP to ping only.

Maybe I didn't explain it right. Please have a look at the attched picture.
The problem is, that the device didn't respond to queries for snmp system information. Normaly if you query a device you will get e.g. SystemUpTime, SysLocation etc. The device can not handle it.

Some more suggestions?

What happens when you use either GetIF or snmpwalk on the cacti server trying to query that device? Something like: snmpwalk -c public -v 1 127.0.0.1 system

You are either blocked by a firewall, or have the incorrect snmp readstring.

maybe the device is not ready to answer to system information snmp querying packets...

That is also possible. The way to verify is to run the following:

snmpwalk -v 1 -c <your_community> <your_ipaddress>

If I have input

snmpwalk -v 1 -c public <IP-ADDRESS> 1.3.6.1.4.1.14848.2.1.2.1.5.1

I got

SNMPv2-SMI::enterprises.14848.2.1.2.1.5.1 = INTEGER: 204

I think it's a step forward.

Please walk the entire device and post the results.

That's m yproblem. I can't walk the entire device. It's a problem by the vendor. Isn't it possible to take the values by the OIDs? In the meanwhile I'm really frustrated...

If you are using the latest cactid, change your availability to SNMP or Ping. You device should start to work.

Do I really have to change to catid? Is there no other possibility?

Don't know. You should test what I recommended and see what happens.
