Just had a look at the 15.18 Beta changelog and stumbled upon this:
In a nutshell: in case an MX67C is deployed in a warm spare environment, cellular backup is utterly useless and even expected behavior? Is this an „end of the line“-statement or will the „expectation“ possibly change someday?
This kind of setup poses a „last resort config“ for many customers. They would like to provide hardware HA and just in case everything else regarding wired connectivity fails, it‘s just natural to have (at least) an LTE fallback option. What‘s the reason to deploying these kind of devices then if such a crucial feature is missing because it‘s „expected behavior“?
My question therefore is: is it going to stay this way or are we going to see both features (HA and cellular backup) in 15.x somewhen?
its already for a long time in the change logs. i dont know if this is correct... why would it work in standalone but not in warm spare... did someone test this?
The whole point of the built-in cellular is for redundancy, along with warm-spare. This seems like a major flaw in my eyes.
Exactly that's what it is. What's the point in having a setup that's as highly available when the "last line of defense" won't work anyways?
I'd be more than grateful if the Meraki folks could clarify this. 😬
Hello @CptnCrnch
The Cellular Failover in an HA Scenario is not officially supported by Meraki as there are Certain Connection Monitoring restrictions over Cellular. It, however, may work in the following order of failovers - https://documentation.meraki.com/MX/Deployment_Guides/MX_Warm_Spare_-_High_Availability_Pair#Cellula...
This is the most up-to-date KB on the expected behavior of Cellular on an HA pair. I would recommend submitting a feature request from the dashboard using the "Make a Wish" button since this is currently the expected behavior. Feel free to let me know or reach out to support@meraki.com if you have any questions.

Meraki Team
