PowerEdge 2950 DRAC SNMP Failure

Good Morning Folks,

I did my best to search Google and the Dell Forums for this but there doesn't appear to be anything helpful for the situation I am in. We have a few PE2950's racked in our data center, they primarily provide VMs for testing and some development. We are attempting to add them to our monitoring system (Nagios), and keep having an issue where nothing comes back. I began by running a MIB explorer against the MIBs we have on file for these servers and the DRAC 5 cards installed in them. This provided no helpful data to us as every OID we tried failed with the following message

"enterprises.674.10893.1.20.110.13.0 = No Such Object available on this agent at this OID"

So I hit up google for a better answer and a better idea of what the heck is going on. I found one site that walked you through how to monitor the temperature using the DRAC and the SNMP OIDs associated the the temperature sensors. These failed with the above message. So being Mr. Curious I began running SNMP walk against the OID removing one section at a time until I got a response. The response came from OID "1.3.6.1.4.1.674" which produced the following data:

[root@redacted~]# snmpwalk -Os -c public -v 2c [redacted ip] 1.3.6.1.4.1.674
enterprises.674.10892.2.1.1.1.0 = STRING: "Dell Remote Access Controller 5"
enterprises.674.10892.2.1.1.2.0 = STRING: "DRAC 5"
enterprises.674.10892.2.1.1.3.0 = STRING: "This system component provides a complete set of remote management functions for Dell PowerEdge servers"
enterprises.674.10892.2.1.1.4.0 = STRING: "Dell"
enterprises.674.10892.2.1.1.5.0 = STRING: "1.65 (Build \"12.08.16\")"
enterprises.674.10892.2.1.1.7.0 = STRING: "https://10.0.1.12:443"
enterprises.674.10892.2.1.1.11.0 = STRING: " "
enterprises.674.10892.2.1.1.14.0 = INTEGER: 6
enterprises.674.10892.2.1.2.1.0 = STRING: "1.65"
enterprises.674.10892.2.2.1.0 = INTEGER: 3

No matter what I try this is the only response I can get from SNMP to the DRAC IP address either internal or external, it does not matter it will return that data. Standard OIDs that I can find through a MIB explorer or the internet fail. What am I missing? I know the error means that the OID meant nothing to the DRAC but why? If the MIB has it listed why is the DRAC returning an error that the object does not exist in the DRAC agent?

Any help would be appreciated!

Thank you,

Jon
