Hi, I have to do PoC at client to show CP capabilities as a TACACS+. I am new to TACACS+, kindly need documentation for how to do this task. I have below listed vendors for which I have to do AAA task. I am confusing how authorization will work. Will I need to configure all users in CP, who are access devices and get 2 factor authentication from AD and RSA. And assign separate Role to them. And configure Separate Service for each vendor and assign Read-write, Read-only permission according to their Permission metrix. Or is there anyother way to do this Authorization task. I am totally new to AAA. Vendors are: FireEye, PaloAlto, Cisco, Juniper, Symantec, Bluecoat, Airtight, Arbor, Huawie and Pulse Secure etc If possible, I can get documents for these vendors. Regards, Atif.
