Cisco AAA with TACACS+ and ISE on IOS-XE: Command Authorization, Accounting, and Audit Trails

If your network devices still rely on a shared enable password and a local username list, you're one leaked credential away from a very bad day.

This guide walks through a complete AAA deployment on Cisco IOS-XE using TACACS+ and Cisco ISE — from defining server groups and method lists to command authorization sets, accounting configuration, and full ISE policy design. Real CLI output and a copy-paste-ready full config included.

Topics covered:

• TACACS+ vs RADIUS — when to use which
• ISE shell profiles and command sets for role-based access
• Local fallback user and safe AAA deployment order
• Command authorization and exec accounting on IOS-XE
• SSH hardening and management ACLs
• Debugging TACACS+ failures and ISE Live Logs
