Adding Network Devices to ISE?

Question

The documents on this seem unclear.
I am working on a new deployment of ISE and am having difficulties adding the network devices to it.
When I add the first device I have no issues, using the devices ip address (not loopback) and a mask of 192.
When I try to add a second device using its ip address (again not a loopback) and the network mask of 192, I get an error message indicating "given ip subnet overlaps with the exisitng network: device A (example).
My question is this what mask am I suppose to use for the devices I am trying to add to ISE if I do not have loopback addresses?

Hi,
If you want to add a single device eventhough it is not a loop back just use /32.
You're right, they don't mention anything on the documentatioin.

They do however say look at this document:

–You can define a specific IP address, or a range with a subnet mask.
–You cannot define two devices with the same specific IP addresses.
–You cannot define two devices with the same IP range. The IP ranges must not overlap either partially or completely.
