How to delete a connect link in Fabric Infrastructure Topology

[forev22]

Hi  Guys.

I used DNAC 1.3.3.7 with some C9300 and C3560-CX for extended node in my small company.

But, one issue is... when I change a connect switch link from first old to second new, 

couldn't delete first connected link at topology screen... even re-provisioning after delete in inventory.

How to delete this? 

Anyone who can help me? 

Thanks.

Those links are discovered when the switch is resynced in inventory. When DNA recognizes they've been removed, the links will turn red, and you have the option to delete them.

Nope... some days passed, but that link recognized live by DNAC. never turn to red.

We have that same problem. 
Using an AutoLAN automation where an uplink was visible. These switches are provisioned and the links are visible. Yet the interface of the remote switch is off. Other switch the interface is configured as switchport and a client is connected. Yet the links between switches still exist. In Inventory Topology and Fabric Infrastructure.
How to remove them from the Topology?

Bump. I have the same issue! How do I delete the old links?

In Dnac 2.2.3.x, I cant recall exact version, they introduced an option to delete the link. You have to be in topology view and select the red line and you will see the option to delete

Same problem but no red link as the device still indicate down link after having removed switches connected on a port. So my distribution switch has health to 8 because two links are down, but it is normal as these two switches historically connected are removed. No possibility to inform DNA-C than these two ports are normally down now. 
Bug, any idea, not possible?

This issue is still present in DNAC Version 2.3.5.4

A link which is physically down does not turn red in topology (at least not in reasonable time) even after a device resync from inventory.

Any tips on how to force the link to become displayed as down (red) so it can be deleted?

I just ran into this as well, the link showed "blue" in the "Provision -> Fabric Sites" overview. When we looked in the "Tools -> Topology" section the links showed "red" and could be removed there.
