6.8.3 Configuring a TACACS+ Server
6.8.3.1 Default Configuration
When an SBx3112 switch is initially booted up, there is no TACACS+ server configured.
6.8.3.2 Configuration Guidelines
TACACS+ users have a security level of 1 to 15; for the SBx3112, 1 corresponds with User, 7 with Manager,
and 15 with Security Officer. Therefore, the Network Access product users “manager” and “securityofficer”
correspond to the TACACS+ users “$enab7$” and “$enab15$”. If these are not configured in TACACS+, then
TACACS+ will refuse the authentication when a user tries the command “Enable manager/securityofficer”.
Also, the syntax of this command depends on the level of the user; someone at the User level will have both
manager/securityofficer as options while someone at the Manager level will have only securityofficer available (if
they are data filled at the TACACS+ server).
6.8.3.3 Configuration Procedure
The following procedure shows the commands used to set up a TACACS+ server.
