For example: shell:priv-lvl=15 NOTES: • If the privilege level is zero (that is, blocked), then authorization will fail and the user will be denied access to the switch. • If the privilege level is higher than one, the user will be placed directly in Privileged Exec mode. Note that all commands in Privileged Exec mode require privilege level 15, so assigning a user a lower privilege level will be of no value. • A privilege level greater than 15 is invalid and treated as if privilege level zero had been supplied. • The shell service must be enabled on the TACACS+ server. If this service is not enabled, authorization will fail and the user will be denied access to the switch. Authentication, Authorization, and Accounting 301
