Migrating to Cisco ACS

[Jean-Pierre de Villeres]

We are planning to migrate our Cisco network devices login using Cisco ACS and authenticate through TACACS and/or RADIUS. Please advise on the below details:

1. what cisco IOS version will support this (we mostly have ASA Firewall, Catalyst Switches, ISR, and the like)

2. best practice to not lose remote access to the network devices.

3. sample configuration required for the implementation.

 - Your post is too broadened and lot of what you want to do also depends on 'understanding documentation' (...) ; while this forum would be more appropriate when you encounter   a specific issue on your project-path.  You should also look into ISE ,as it is  a followup of ACS ; have a look at the differences here : https://communities.cisco.com/docs/DOC-63901
