MS130 switches causing UDLD errors

[redsector]

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.

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
