MS130 switches causing UDLD errors

I have a few MS130-8X switches and they are causing UDLD-errors at the port of the connected switch. Anybody here with the same issue? The uplink goes to an MS120 switch. The MS120 reports UDLD error on the port where the MS130 is connected.

Kind of a big deal

Is this when using the SFP ports and a fibre?  We have a MS130-12X connected to an MS355-48X, but over copper.  That combination doesn't have an issue.

connected by copper.

I did open an case for this issue. Will inform you as soon I have more information.

Meraki is still working on this issue. Ticket / case is in work.

Are you sure that the cabling is OK?  If you ruled that out then ...

In rare circumstances, there are UDLD errors and spanning tree errors caused by a physical issue at the component level on only MS120's. It seemed to mainly be effecting ports 10/11, but after searching I do see some other scenarios where this happened with ports 3. The issue should only impact negotiation at 10 and 100mbps

Shure good cables, I testet several used and new cables. Issue on alle copper ports. Issue occures also when connected with 1Gig speed.

Hey there!  Seeing some weird UDLD issues with a MS130R switch that we have at one of our sites also.  Worked extensively with Meraki support, we troubleshot all layer 1/2 issues.  I put a MS120-8 port switch in place while Meraki sent a new MS130R.  That temporary switch had no issues at all, no UDLD errors.  I get the new MS130R, put it in, UDLD issues and switch goes down, I'd say every 6 hours to a day or so.  Engaged support again, but they are looking at layer 1 issues again.  Kind of starting to think the MS130(R) ruggedized switches may have a manufacturer defect or something.  Next step for us is to install MS120 again and perhaps move the MS130R to our main stack and connect via fiber there.  If it drops there too I would be extremely confident there is no layer 1/2 issues, and we're looking at faulty equipment DOA from Meraki.  Our uplinks are 1G fiber, SFPs appear to be on the compatible list for the switches.

 

Any luck with TAC on your case?
