When I try to create an uplink between the above two switches through an SFP port, I get the following error on the IE 2000 switch
Where is the problem and what is not set correctly in the switches?

Can you confirm how you have created those links, as unless that switch is running in a VSS ( single control plane) you will require two separate physical links in their own trunk or access mode connecting to those two switches
Please rate and mark as an accepted solution if you have found any of the information provided useful.
This then could assist others on these forums to find a valuable answer and broadens the community’s global network.
Kind Regards

The error message is due to UDLD. That is a Layer 1 issue.
