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] [email protected] DEVSTAT-SNMP-Poller polling #7
SNMP-W-EINVALIDMESSAGE-Received invalid message from SNMP agent 172.23.13.29,
SNMP-EGETRESPONSE-In response to Get(.18.104.22.168.22.214.171.124.126.96.36.199.7.2)
SNMP-EWRONGTYPE-Wrong type (GAUGE-32) instead of required type (64-bit
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":
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.
