I need to be able to export a list of our Meraki networks and their LAN IP address to be able to do a bulk import into Cisco ISE so they can be added as NADs. We are wanting to enable 802.1X on our Meraki devices.
Have you looked into the dashboard API? It would be ideal for a job like that.
Check the following link to get started:
I agree with @BrechtSchamp, the API is the way to do this. I'm thinking this endpoint should do it:
I would personally avoid adding specific device IP addresses, and instead add the subnet that they are in. Then this whole exercise becomes trivial.
It also means if you deploy additional 802.1x devices you don't need to touch ISE.
