Configuring TACACS+ Access Level Mapping

The TACACS+ Access Level Mapping table lets you configure up to three rules that map TACACS+ privilege (priv-lvl) values to the device’s user levels (Security Administrator, Administrator, and Monitor). For example, you can map TACACS+ priv-lvl=1 to the device’s Monitor user level.

The table is a child of the TACACS+ Servers table (see Configuring TACACS+ Servers).

If the TACACS+ Access Level Mapping table contains rules and a TACACS+ response includes a privilege level that is not listed in the table, the device rejects the user's login attempt to the web interface or CLI.
If the table is empty, priv-lvl 15 maps to Security Administrator; all other values map according to the 'Default Access Level' parameter.

The following procedure describes how to configure TACACS+ access level mapping through the Web interface. You can also configure it through ini file [TacacsPlusAccessLevelMapping] or CLI (configure system > tacacs-settings > tacacsplus-servers > access-levels).

To map a TACACS+ privilege level to the device's user levels:
1. Configure a TACACS+ server in the TACACS+ Servers table, as described in Configuring TACACS+ Servers.
2. In the TACACS+ Servers table, select the server you added.
3. Click the TACACS+ Access Level Mapping link located below the table; the TACACS+ Access Level Mapping table appears.
4. Click New; the following dialog box appears:

5. Configure a TACACS+ Access Level Mapping rule according to the parameters described in the table below.
6. Click Apply.
7. Save your settings to flash memory.
