DFM 2.0.10 does not show switches - errors in DFM.log

MATTHIAS SCHAERER · ‎02-08-2008

Hi,

First of all a high number of devices does not show up in DFM (customer tells me that it is the switches that do not show up, routers seem to be ok) in DFM. Furthermore in DFM.log I get the following message for a high number of devices:

[31-Jan-2008 16:24:07+770ms] t@17840 DEVSTAT-SNMP-Poller polling #7

SNMP-W-EINVALIDMESSAGE-Received invalid message from SNMP agent 172.23.13.29,

port 161

SNMP-EGETRESPONSE-In response to Get(.1.3.6.1.4.1.9.9.48.1.1.1.7.2)

SNMP-EWRONGTYPE-Wrong type (GAUGE-32) instead of required type (64-bit

unsigned integer)

SNMP-EAGENTBUG-Agent violates protocol; ignoring response

I first interpreted the message as mismatch of the SNMP versions of DFM and the device, however the device does not show any errors with "show snmp":

myhost>sh snmp

Chassis: xxxx

Contact: xxx

Location: xxx

4804631 SNMP packets input

0 Bad SNMP version errors

0 Unknown community name

0 Illegal operation for community name supplied

0 Encoding errors

45737335 Number of requested variables

0 Number of altered variables

3538585 Get-request PDUs

1264648 Get-next PDUs

0 Set-request PDUs

...

I have searched for bugs related to SNMP versions in DFM 2.0.10, no success so far. I am unsure if the problem with the devices that do not show up and the errors in the logs are related or not at this moment; however I mention both in case they concide.

Has somebody any information or an idea where I could continue my troubleshooting?

Thanks for any hint.

The DFM is logging errors in the DFM.log file regarding an unexpected 32-bit answer where actually the object should be 32bit. Following link may help you

Sorry, was out of the office for a long time.

I have read your post but I could not find any help in the link you sent. All information I have found was about customizing DFM 1.1 or 1.2 and in my case I have DFM 2.0.10. Can you give me a hint what in which part of the link you see a relation to my problem.

I know that my objections may sound like whining and complaining. I don't mean it that way, I am grateful for any help but in your case I do not yet understand what you wanted to tell me with your post.

Thanks for support anyway.
