Extreme Management center: Links are missing on map overview

When trying to add a link which should normally be seen on the map overview, it says:
WARNING: Port 1/19 already has a link to:
IP: 10.110.255.210
MAC: B4:2D:56:35:5C:01
Port: 2/50
Discover Protocol: LLDP
Do you wish to overwrite this information?

But why is it not showing that link then in the map overview?

Thanks for helping me with this

Hi, after upgrading the XMC version to 8.3.0.111, it did show the links.
Thanks all for your help.

In such situations it's often helpful to check content of network-monitor-cache and maybe clear this cache.

What resolved this issue for me was turning on Collect Device Statistics for all the switches. I had a few that were set to disable instead of historical. Once I set this and refreshed devices the links all started showing up.

Still having issues with one switch, but it's had attitude problems lately anyway.

With the log message, it looks like the port 1/19 already has link connected to the remote side which has above information (port 2/50, IP: 10.110.255.210, etc.). So when you are trying to manually add a link on the port 1/19, above log is displayed. Please kindly check why the port 1/19 already have that information.

Best regards,
