Re: NPM 12 Stack Data Ring error

Jump to solution

I figured this one out.. Apparently you have 2 or more switches in the data stack, it can't draw out the diagram..... I hope I'm wrong!

Try this as a test: Login to solar winds and check one of your 2 switch stacks. The data diagram shows up fine with only 2 switches, but when you have more than 2 it does not seam to work

I will post a pic of it working and not working.

More than 2 switches show the ring topology correctly for me.

Dan,

I've been seeing some issues in the reporting of power/data stack rings. I noticed I had some "ghost" provisions were I stacked switches for an IOS upgrade, but later divided them up to deploy in different locations. I've attached the data ring for a stack of 7 3850s I have. I'm getting the same issue with certain stacks. Will update once I have some more time to troubleshoot.

Running 03.06.03E

Dan,

Just for giggles and to compare with what I've seen with "ghost" switches. Check how many switches are provisioned since I've seen that if there is a member provisioned but not in a "ready" state that it throws Solarwinds a curveball in data ring reporting. I'll post an update once I remove the "ghost" provisioned switches.

no problems with Version 03.06.04.E

maybe running the following commands will shed some light on problem ?...

#sho switch neighbors

  Switch #    Port 1       Port 2

  --------    ------       ------

      1         5             2

      2         3             1

      3         2             4

      4         5             3

      5         4             1

sho switch stack-ports

Switch#   Port1     Port2
----------------------------
1         OK        OK
2         OK        OK
3         OK        OK
4         OK        OK
5         OK        OK
