I had a quick question regarding the trunking mechanism on the Meraki switches. When you set a port to trunk mode and allow all vlans on that trunk, will it automatically allow vlans on the trunk as you assign ports to their respective vlan? For instance, if I assigned port 1 to vlan 300 and port 2 to vlan 400, will the trunks automatically start trunking for and forwarding for those vlans on the trunk? Or is it better to manually specify exactly which vlans are allowed on the trunk to make sure they are forwarding on that trunk? On IOS I would just run a "show interfaces trunk" and a "show spanning-tree interface" to see what the forwarding action was on a specific interface. Unfortunately I cannot find a way to verify which vlans the trunks are forwarding for, its kind of annoying actually.

Thanks for the reply! This begs the question: If there is no way to "create" vlans directly on the Meraki switch, is it safe to assume that all possible vlans are already "created" and that all you have to do is assign vlans to ports and trunks? Ive spent my entire career having to "create" vlans before they can be used, but the Meraki switches seem to already know about them ahead of time. I'm a little confused as to how that works.
