Hello,
I currently have a problem that interfaces show a link by LED. I also see incoming multicast traffic with the command “show interface ethernet rates”. Autonegotation of the ports has also worked, but the operational state of the ports remains down.
What could be the reason for this?

Thanks a lot
Harry

try:

X is the port number

show interfaces ethernet 1/x link-diagnostics
