What specifically was your provider asking that had support contradict their own documentation? Need more context to be able to respond appropriately. ^_^ That being said, those Cellular Failover Rules do indeed append up if WAN 1 goes down, however they by default will only apply to an actual cellular USB device being used. If your using say a 4G connection (mifi) that is connected into WAN2 (via Ethernet connection), the MX has no clue that the median at which it traverses is cellular. All it knows is WAN2 is WAN2. Meraki doesn't have a specific set for WAN2 for some unknown reason (I pray one day they will add it), but in the meantime, few of us know of a trick where you can have support make the cellular rules 'act' as the WAN2 rules. However only support can enable that for you.
