    NPM 12 Stack Data Ring error


      Anyone else experiencing this error with NPM 12? The power stack data displays fine, I just get this nasty error when I add the "Stack Data Ring":


      Unable to construct the data ring diagram because the information required to show the diagram is missing or is not complete. Make sure the device is configured properly.


      This is the case for every single stack we have.

          I just upgraded to NPM v12 and 2 of the 3 stacks are showing the same error as you are. I am looking thru the differences now to try and determine what they might be.

            Listed as known issue for old IOS versions, but I haven't personally seen it and don't know exactly which IOS version are hit by it to determine if it applies to you.

            Cisco Switch Stacks do not provide enough data for drawing stack rings

            Issue: Some Cisco Switch Stack IOS versions do not provide enough information for drawing stack rings.

            Work-around: Upgrade the IOS on the switch stack to the latest version or contact the vendor.

              I have dozens of stacks, from 2 to 8 switches.  They all report the data and power stack fine, and draw the power stack, but none of them draw the data stack ring.  Same message as above  Running a 3.6 ver

                I finally got the error message you are receiving but mine is on a stack of 9 3850s running 03.06.03E. I've checked the poller, but depending on your settings if the poller isn't assigned to that device (atleast in my setup) then the stack tab doesn't even show up. One thing I did find strange as I was investigating this was one of my stack rings is apparently not reporting/using power...more issues yay See below

                    beardedgeeknc, maybe problem is your stack cabling/configuration ?...

                        Thanks for pointing that out, but it's how I set it up since the switches aren't located in the same rack but next to each other. 5 in 1 rack/ 4 in the other.  I don't think that would cause the ring to not report correctly to solarwinds though. You should be able to cable them up in any way and then get a very confusing stack ring

                    • Re: NPM 12 Stack Data Ring error

                           Actually, I'm seeing this problem on a 3850 running 03.07.04E (Paired nodes, no Stack data) and I'm missing one out of a four-node setup of 3850's running the same version.  Has anyone seen similar of late?  I've ensured that the stack poller is both compatible and applied, and that all stack related elements are being polled, but no joy.

                          Are the switches/stack ports reporting all up on the switch side? Check provisioning as well.

                          "sh switch" and "sh switch stack-ports" should let you know that they are all connected and provisioned properly.

                              The Switch Stack Members pane provides data, which matches the sh switch results 1 for 1.  (hw version v02)

                              Sh switch stack-ports show both ports for both switches as OK.

                              Resources view in SW shows that both stackports are listed and polled, as well as the related StackSub resources.

                              sh switch has leaves 1-3 all good to go and matching each other (hw v06), but the 4th switch is version 0.  Possible problem there, even though all are listed as ready?

                              Sh switch stack-ports show both ports for all switches as OK.

                              Resources view in SW shows all four sets of stackports and StackSub resources as present and polling.

                                  The 4th switch being version 0 may just be a reboot to fix as long as it seems to be working normally. It could however impact your data stack reporting. Can you post the output of your "sh switch" cmd on the quad stack just so I can lay eyes on it ?

                            • Re: NPM 12 Stack Data Ring error

                              Is there a way to not poll Stack-power but keep the data ring?  We have multiple dual-stacked 3650's. Those switches do not have the powerstack capability


                              I have multiple log entries where we see that SolarWinds tries to gather the information:

                                   2016-10-31 17:23:46,099 [STP SmartThreadPool Thread #199568] WARN  SolarWinds.NPM.Pollers.Technology.SwitchStack.CiscoSwitchStackPollerHelper - 10.xx.xx.xx - StackPower data was not discovered


                              How could we clean this up?
