RV042G SNMP query returns empty sysObjectID?

stevengoncalo · ‎08-10-2013

I have been trying to track down why my openNMS system has not been recording statistics from my new RV042G router.

It appears the router is not reporting sysObjectID correctly.

snmpwalk -v 2c -c public 10.0.0.1 sysObjectID

SNMPv2-MIB::sysObjectID.0 = OID: SNMPv2-SMI::zeroDotZero.0.0.0.0.0.0.0.0.0.0

snmpwalk -On -v 2c -c public 10.0.0.1 sysObjectID

.1.3.6.1.2.1.1.2.0 = OID: .0.0.0.0.0.0.0.0.0.0.0.0

From CISCOB_RV0xxV3.mib, I expected .1.3.6.1.4.1.9.6.1

--CISCOSB-MODEL-MIB { iso(1) org(3) dod(6) internet(1) private(4)

-- enterprises(1).cisco(9).otherEnterprises(6).ciscosb(1) }

Is this a known fault with the SMTP implementation on this router?

Is there any way to get it to report the proper value?

I dont think any of my network monitoring tools will load the correct mib if the

sysObjectID is reported incorrectly.

By way of comparision, on a netgear switch

$ snmpwalk -On -v 2c -c public 10.0.0.20 sysObjectID

.1.3.6.1.2.1.1.2.0 = OID: .1.3.6.1.4.1.4526.100.4.18

My hardware/firmware is:

snmpwalk -v 2c -c public 10.0.0.1 mib-2.47

SNMPv2-SMI::mib-2.47.1.1.1.1.2.1 = STRING: "RV042G Gigabit Dual WAN VPN Router"

SNMPv2-SMI::mib-2.47.1.1.1.1.7.1 = STRING: "RV042G"

SNMPv2-SMI::mib-2.47.1.1.1.1.8.1 = STRING: "V01"

SNMPv2-SMI::mib-2.47.1.1.1.1.9.1 = STRING: "v4.2.2 .08 (Apr 26 2013 19:09:19)"

SNMPv2-SMI::mib-2.47.1.1.1.1.10.1 = STRING: "v4.2.2 .08 (Apr 26 2013 19:09:19)"

SNMPv2-SMI::mib-2.47.1.1.1.1.11.1 = STRING: "NKSxxxxxxxxxx"

SNMPv2-SMI::mib-2.47.1.1.1.1.12.1 = STRING: "Cisco Small Business"

SNMPv2-SMI::mib-2.47.1.1.1.1.13.1 = STRING: "RV042G"

Hi Steven, thank you for using our forum, my name is Luis I am part of the Small business Support community. Did you try to update your device firmware? The currently firmware is 4.2.2.08 for RV042Gv3, you can download it here.

I advise you to create a backup of your configuration before install the new version, and also after that, please perform a factory reset. Then you can upload your previous configuration.

Let me know if that work for you.

I hope you find this answer useful

Greetings,

Luis Arias.

As shown above, I was already upgraded to version 4.2.2.08.

I re-downloaded it and flashed the unit again to be sure.

All settings got reset to factory defaults.

After making one change to enable SNMP, it still returns all zeros for the sysObjectID.

I have seen references to the RV042 originally being issued as a Linksys product. Maybe someone removed the Linksys

sysObjectID in the code without putting in the new CISCO values?

Would it be safe to go backwards to the RV0XX-v4.2.1.02-20120118-code.bin release to see if this is a new bug?

Could any other RV042G owner please run the following linux/mac/bsd command:

snmpwalk -On -v 2c -c public 10.0.0.1 sysObjectID

(replacing 10.0.0.1 with the LAN side address of your router) and reply to let me know if all unts just return a zero ID?

It seems unlikely that my unit is uniquely broken, but it aslo seems unlikely that SNMP protocol could be that broken on all these routers without other users complaining.
