Requirements
As shown in Figure 46, you are required to configure the switch so that Telnet 
users logging into the switch are authenticated and authorized by the TACACS 
servers.
A TACACS server with the IP address 10.110.91.164 is connected to the switch. It 
will be used as the authentication, authorization and accounting server.
On the switch, set the shared keys for exchanging authentication, authorization 
and accounting messages with the TACACS server to expert. Configure the 
switch to strip domain names off usernames before sending usernames to the 
TACACS server.
On the TACACS server, configure the shared keys to expert for exchanging 
messages with the switch, and add Telnet usernames and login passwords.
