I've got an MX67. WAN2 is set up as a fail over WAN but my issue is that it's actually an LTE router. I do not want all traffic to flow over that WAN when WAN1 dies. I only want mission critical traffic to run over that WAN.
How can I accomplish this. All mission critical stuff are on their own VLAN so restricting traffic via VLANs or Subnets is OK by me.
Giving access to lots of information actually often makes customers' working lives much more complex. If you have an issue, your license allows you to contact Meraki Support - let them worry about the complexity of (for example) When does CPU utilisation become excessive? Meraki is pretty obsessive about making technology as simple as possible.
(BTW - if you haven't found it before, Meraki makes available an overall MX appliance utilisation number, under Organization > Summary report)
