Application of a Data Cap on Meraki MX link or MG

[TBee]

Hi,

Is there a way to apply a data cap on one of the WAN links on a Meraki MX or MG.

Basically we are proposing a SD-WAN solution, which will use a broadband primary circuit and a 4G Secondary, via a MG (might have to use the customers existing gateway).

On a normal day it is expected that both links will used to carry traffic. However the 4G link has a monthly allowance, that based on analysis of use, shouldn't be exceeded.

Is there a way of either monitoring and alerting on the usage of the 4G link, at say 80% or applying a cap an alerting?

I can't see it on the dashboard for the MX and don't have visibility of an MG to check.

There's no way to do this natively within the Dashboard, that I'm aware of.   You would be able to monitor cellular usage, however, via the API - you could then trigger additional API-based controls, once usage reaches your preferred threshold(s):

Perhaps by progressively stepping up cellular firewall rules, as the limit approaches - maybe ultimately allowing only the most critical / bandwidth thrifty applications?    https://developer.cisco.com/meraki/api-v1/#!update-network-appliance-firewall-cellular-firewall-rule...
