Hello Darren,
 
Thanks for sharing the design materials 
 
I had a look at the documents which you have mentioned in the above post
 
I could see that the one below gives best practices 
 
https://documentation.meraki.com/MS/Meraki_Campus_LAN%3B_Planning%2C_Design_Guidelines_and_Best_Prac...
 
Whereas this one below gives campus design that too specific to switches
https://meraki.cisco.com/product-collateral/meraki-campus-deployment-guide/?file
 
Whereas I am actually in need of validated Software defined (LAN/WLAN )design guides for 
 
1. Small sites ,
2. Medium sites,
3. Large campus sites and
4. Extended campus sites.
 
I could see that such reference material is available for Cisco DNA - SD Access. 
 
If you have such similar materials in Meraki, could you please share it in this post.
 
Thanks,
Prabhu
