Level switching authentication for Telnet users by an
HWTACACS server
Network requirements
As shown in Figure 31, configure the switch to:
• Use local authentication for the Telnet user and assign the privilege level of 0 to the user after the
user passes authentication.
• Use the HWTACACS server for level switching authentication of the Telnet user, and use local
authentication as the backup.

Configuration considerations
1. Configure the switch to use AAA, particularly, local authentication for Telnet users.
• Create ISP domain bbb and configure it to use local authentication for Telnet users.
• Create a local user account, configure the password, and assign the privilege level for the user to
enjoy after login.
2. On the switch, configure the authentication method for user privilege level switching.
• Specify to use HWTACACS authentication and, if HWTACACS authentication is not available, use
local authentication for user level switching authentication.
• Configure HWTACACS scheme hwtac and assign an IP address to the HWTACACS server. Set the
shared keys for message exchange and specify that usernames sent to the HWTACACS server carry
no domain name. Configure the domain to use the HWTACACS scheme hwtac for user privilege
level switching authentication.
• Configure the password for local privilege level switching authentication.
3. On the HWTACACS server, add the username and password for user privilege level switching
authentication.
