Re: NPM 12 Stack Data Ring error

Jump to solution

dstj,

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

you're probably right.  Any chance of going to version 3.6.4.E ?

A few of us on this thread are running it without issue.

Sadly no. I must wait on my Corporate overseers to finish bug scrubbing 3.6.4E and with some of the downsizing up there recently...no clue when that will or ever be done.

generally... check out Erdos - Online Graphviz Viewer

you can convert the output of the stack detail into a dot-language specification like this:

digraph stack {

n1->n2;n1->n6;

n2->n3;n2->n1;

n3->n4;n3->n2;

n4->n5;n4->n3;

n5->n9;n5->n4;

n6->n1;n6->n7;

n7->n6;n7->n8;

n8->n7;n8->n9;

n9->n8;n9->n5;

}

if you pick a circular layout (circo) then you end up with a picture like this (which looks good to me)

     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.

tr,

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.

(results: 3850 pair w/ 3.0.7.04E)

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.

(results: 3850 quad stack)

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?
