Hi @Mabouzid , what’s the fibre between both switches?

Might be a silly question….have you tried swapping the ends round on one of the fibre patch leads?

Ah, so we’re beyond troubleshooting a layer 1 issue.

 

Have you contacted Meraki support?  Is the 9300 on the latest firmware?

You’d be better served ringing support directly.  You can find their number in your dashboard.
