SNMP issues with RV082

Does anyone else poll this router with SNMP?

We are using firmware version:

We are having problems with the traffic counters, some of them appear to be implemented as 16 bit counter instead of 32 bit counters. The reason this is causing problems is that they roll over (at 65,000) to 0 in less than our minute polling cycle, really skewing our metrics.

The counter for the Lan (interface 2) seems to be functioning properly, however interfaces 3 and 4 (WAN and DMZ / WAN2) rollover at 65000.

IF-MIB::ifInOctets.1 = Counter32: 137634

IF-MIB::ifInOctets.2 = Counter32: 1865677943

IF-MIB::ifInOctets.3 = Counter32: 12450

IF-MIB::ifInOctets.4 = Counter32: 49354

Look at counter IF-MIB::ifInOctets.4 5 seconds later:

Tue May 11 08:38:36 EDT 2010

IF-MIB::ifInOctets.1 = Counter32: 137634

IF-MIB::ifInOctets.2 = Counter32: 1865836207

IF-MIB::ifInOctets.3 = Counter32: 13167

IF-MIB::ifInOctets.4 = Counter32: 12900

Any suggestions?

Re: SNMP issues with RV082

Looks like a bug.

I'm using the same firmware, and the bug can be seen with one reading:

$ snmpwalk -v 2c -c public


IF-MIB::ifDescr.2 = STRING: ixp0
IF-MIB::ifDescr.3 = STRING: ixp1
IF-MIB::ifDescr.4 = STRING: ixp2

IF-MIB::ifInOctets.2 = Counter32: 2882720251
IF-MIB::ifInOctets.3 = Counter32: 59554
IF-MIB::ifInOctets.4 = Counter32: 31339

IF-MIB::ifInUcastPkts.2 = Counter32: 114769131
IF-MIB::ifInUcastPkts.3 = Counter32: 4291658323
IF-MIB::ifInUcastPkts.4 = Counter32: 4292343584

The unicast packet counters seem correct, the LAN counters (both byte and packet) seem correct, but the WAN (both WAN1 & WAN2) byte counts are flawed, i.e. no relation to the packet counters.

Re: SNMP issues with RV082

Here's what we're talking about, a graph of the snmp values, and one of the real values:

Where do we report this bug?
