TACACS+ Authentication
Configuring TACACS+ on the Switch

configuration in your TACACS+ server application for mis-configura-
tions or missing data that could affect the server’s interoperation with 
the switch. 

8.

After your testing shows that Telnet access using the TACACS+ server is 
working properly, configure your TACACS+ server application for 
console access. Then test the console access. If access problems occur, 
check for and correct any problems in the switch configuration, and then 
test console access again. If problems persist, check your TACACS+ 
server application for mis-configurations or missing data that could 
affect the console access.

9.

When you are confident that TACACS+ access through both Telnet and 
the switch’s console operates properly, use the 

write memory command 

to save the switch’s running-config file to flash memory.

Configuring TACACS+ on the Switch

Before You Begin 

If you are new to TACACS+ authentication, ProCurve recommends that you 
read the “General Authentication Setup Procedure” on page 4-5 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
