Hi thanks for your reply.   The problem is that when the meraki 9300 is configured as trunk with the other switch i mentioned i lose connectivity to the cloud.   What i mean is the following:   Meraki switch <---> Third party switch <---> Backbone Switch <---> Internet Router   When the meraki port is configured as access port in a client vlan , it can get to the DHCP server and get a public IP address and get to the internet and register to meraki cloud.   But when the meraki switch in configured as trunk it loses connectivity , so i suppose that i have to program the Meraki switch to be able to get a public (or private if NATed) in order to get to the cloud.   That last config i am missing.   Thanks,   Ditter ...
