Anyone can clarify me how many devices can an ACS 4.2 work with TACACS+ ?.
Is there any limit?, and if exists, which is it and where does Cisco publishes it.
Spent a whole morning and no success reaching for the info.
Ty in advance.
I did a search for this and based of that i found that ACS 4.2 Solution can support up 35000 device. Here is the link from which I got the information :
An appliance-based Cisco Secure ACS server follows at a minimum the same scalability performance of a Windows-based Cisco Secure ACS server. Cisco Secure ACS guidelines and performance analysis show that each ACS server can support anywhere from 20,000 to 80,000 users per server and can scale to support up to 35,000 devices, depending on configuration, platform, and usage scenarios
However internal we have also seen it is recomended to use 500 device per NDG.
I hope this helps.
