incorrect processing of "error-status: noSuchName" response using SNMPv2 protocol for devices behaving like SNMPv1

    Details

      Description

      2016-05-18 ADDED by zabbix team (zalex): this issue description does not reflect the actual problem, see end of discussion in comments to know what is actually wrong.

      After upgrading to 2.2.3 I started noticing lots of the following errors in the console log:

      SNMP error: (noSuchName) There is no such variable name in this MIB on some devices (SNMPv1)
      No Such Instance currently exists at this OID on some other (SNMPv2)

      Examples:
      31427:20140416:090657.570 item [sg300-1.apra.it:IF-MIB-ifHCInOctets.[3000]] became supported
      31427:20140416:090928.297 item [sg300-1.apra.it:IF-MIB-ifHCInOctets.[3000]] became not supported: No Such Instance currently exists at this OID

      31420:20140416:091857.217 item [patton2291.apra.it:IF-MIB-ifInOctets.[8]] became supported
      31420:20140416:091857.219 item [patton2291.apra.it:IF-MIB-ifOutOctets.[8]] became not supported: SNMP error: (noSuchName) There is no such variable name in this MIB.

      The affected devices seem to be only:
      Patton Smartnode gateways: http://www.patton.com/smartnode/
      Cisco SMB Switches: http://www.cisco.com/c/en/us/products/switches/small-business-300-series-managed-switches/index.html

      The items keep going not supported and back. I have a notification for unsupported items and I received more than 2500 mail last night only.
      Probably this devices don't cope well with the new SNMP algorithm in 2.2.3
