    Changed SNMP version, now can't collect statistics

    jlintner

      My environment recently changed our SNMP version from SNMP2c to SNMPv3.  I can go through and change the credentials for the devices in bulk, but it seems to not take, and the interfaces show an 'unknown' status.  Now all we have is ping, so we are missing T1 bandwidth utilization for 700 remote sites. 

      Is there any EASY way to get them all working again?  I hate to remove and re-add all of the routers since most of them have VoIP and discovery takes a long time.

      HELP!

          Roll it back to SNMP2c =)

            What version are you currently on?

                Sorry - I'm running NPM 9.1, SP5.

                    I would recommend upgrading to 9.5 and seeing if the issue goes away as we fixed some issues around SNMPv3.

                        I am using 9.5 SP3 and setting up SNMPv3 polling to Cisco IOS 12.2 ..I am able to validate snmp credentials but machine type is " unknown"...if I do a list resources, there are no interfaces that show up but I am able to see interfaces if i click the node...seems like SNMPv3 is partially working. I have added these parameters on the device

                            Can you try to set your view to 1.   That will include the entire mib tree. 

                            That should tell us that it’s the view that’s the issue.

                                not sure what you mean by " Can you try to set your view to 1"..do you mean in the IOS or in solarwinds? What commands to use ?

                                      I am having the same problem with SNMP V3. Can you please post the snmp v3 settings that you have on your 3750 so i can compare to what i have on mine?

                            • Re: Changed SNMP version, now can't collect statistics

                              I usually click poll and rediscovery when I upgrade mine from SNMPv2c to SNMPv3 or wait until the next rediscovery interval.  Is rediscovery what you are referring to as taking a long time?  I haven't had any problems with mine.  This was in 9.1 and now I have 9.5 but it was the same in both.

                                My original problem was not if SNMPv3 would work, but rather this:

                                I had over 700 devices/sites polling using SNMPv2c, collecting stats on mainly the serial interfaces on our routers along with CPU and memory utilization.  We had a mandate to stop using SNMPv2c and use only SNMPv3.  No problem, right?  Configure the router with the V3 details (user, group, view, etc) and they would poll.  But, try changing the SNMPv2c polled device properties to use SNMPv3 credentials - can't retain any of the historical data - it wouldn't automatically re-discover the device and interfaces again - it would only say 'unknown status'.  The only answer was to remove all interfaces then rediscover/re-add  the device using the V3 credentials - 700+ times!  It took three of us working in our spare time to get it completed in a couple of weeks.

                                SNMPv3 polling was never an issue; it was changing devices from SNMPv2c to use SNMPv3 credentials in Orion NPM!

                                Now, if Solarwinds can solve the SNMPv3 trap issue we'd be good!

                                  anyone know if changing from SNMPv2 to SNMPv3 with version NPM 10.4.2, will wipe out the historical data?

                                      Changing to SNMPv3 in NPM 10.4.2 should NOT wipe out your historical data. I have changed from SNMP v2 to v3 in NPM 10.2.2, 10.3.x and 10.4.x with no issues.

                                       

                                      I just double checked for you in a lab running 10.4.2 and the node has continued polling (see screencap). The double data point at around 18:55 is a forced poll after SNMPv3 was configured.
