Cisco Secure ACS Shell Profile is used for defining permissions to be granted for a shell access requests and then for TACACS+ based device administration policy. In a Shell Profile, we can define the "Default Privilege" and the "Maximum Privilege".
Cisco IOS CLI Shell privilege level can be defined in Shell Profiles and the commands for the Privilege Level can be defined in Command Sets. To create a Shell Profile with both "Default Privilege" and "Maximum Privilege" 9 and a Command Set in Cisco Secure ACS, follow these steps.
