TACACS+

Terminal Access Controller Access Control System Plus (TACACS+) is a mechanism for providing authentication, authorization, and accounting on a central server, similar in function to the RADIUS client.

The ExtremeXOS version of TACACS+ is used to authenticate prospective users who are attempting to administer the switch. TACACS+ is used to communicate between the switch and an authentication database.

For detailed information about TACACS+ and configuring TACACS+, see Security.
