Configuring TACACS+ on the Switch
Before You Begin
If you are new to TACACS+ authentication, HP recommends that you read the
“General Authentication Setup Procedure” on page 9-11 and configure your
TACACS+ server(s) before configuring authentication on the switch.
The switch offers three command areas for TACACS+ operation:
■ show authentication and show tacacs: Displays the switch’s TACACS+
configuration and status.
■ aaa authentication: A command for configuring the switch’s authenti-
cation methods
■ tacacs-server: A command for configuring the switch’s contact with
TACACS+ servers
