Change layer 7 firewall rules for SSID, 700 networks

[Phillip_Crow]

Hello, I need to change the layer 7 rules for one SSID at 700+ networks. These networks are combined with Meraki switches and access points. Is there a way to apply a template to just change this one SSID layer 7 firewall rules? What would you all suggest?

If I understand correctly, your networks are already in a correct template?

Then you just need to change the L7 rules in the template configuration and it will automatically be applied to the SSID.

Sorry no, we are not using templates at this time

You could move to templates but that does require evaluation, testing, and downtime.

If you plan to remain non template bound the API would be the way to go. https://developer.cisco.com/meraki/api/update-network-wireless-ssid-firewall-l-7-firewall-rules/

+1 for API - I prefer this to templates anyway...
