Cisco SD-Access control plane node scale

[loger9901]

Do the Cisco SD-Access control plane node scale numbers listed in the data sheets include MAC address + IPv4 address + IPv6 address, or just client counts.  For example does a single dual stack client count as 3 or more database entries in the control plane (1 for MAC address, 1 for IPv4 address and 1+ IPv6 address) or just as 1 client.  Just trying to make sure I'm fully understanding the scale limits fully.

The number is very close to client count - when you connect to an edge it registers the MAC address to the control-plane. There are edge case where one device would be registered twice, but this doesn't happen often enough to be something you should account for. You should always plan to have some extra capacity when you design your fabric(s).
