I've just installed ACS 5.1 and noticed that it seems to count managed devices differently than previous versions.
I have a 500 count license which should be fine as I have about 100 devices which will use ACS for TACACS. On ACS 3.x and 4.x, I would set up AAA clients by using a wild card for the subnets that host our routers/switches, say 192.168.1.0/24, 172.16.1.0/24 and 10.1.1.0/24. when I do this with ACS 5, I get a Managed Device Count Exceeded error messasge becasue of the potential of more than 500 AAA clients. It seems to be counting every IP address in the subnet as a managed device, even if there are only a handful actually in use. Is there a way around this short of having to manually enter (and maintain) the exact IP Address of every managed switch and rotuer which will use the ACS server for TACACS?
thanks in advance!
