Hi everyone,   we're using and converted a bunch of Catalyst 9300 to cloud managed Meraki-Switches since a few years, they're working (most time) perfectly fine. We also use some 9200CX but in hybrid mode.   A few days ago I saw that the iOS 17.18.1 for C9200CX is supporting the full cloud managed mode. So I've tried it and failed. 🙂    The upgrade was working, the pre-config for migration was working, pinging dashboard etc. was working and after claiming the switch on the dashboard it begins to migrating to the Meraki-FW. It was working like all the 9300 before it.   After adding the switch to a network it shows all the informations and it seems all fine. I tried to configure a port and it wouldn't let me (VLAN > 800). After a few tries it says the switch is limited to 512 VLANs but this was never a part of one of our running configs in CLI nor on the dashboard. I can't access via console (as normal in Meraki) but asks for a username/password. I think the switch sticks between catalyst and Meraki, so we called support and put it back on iOS 17.18.1.  I factory reset the switch and put a completely fresh iOS on a completely erased switch...after pre-config I want to add it again to a network in Meraki...and it don't let me do it because the switch is limited to 512 VLANs and the migration didn't even start this try.   We deleted the switch from the inventory and want to try it tomorrow again, maybe there was some configs saved in the dashboard...   Is this part of the iOS as an ED release? Or a bug? Has anyone tried to migrate a C9200CX to cloud managed mode? ... View more
