TACACS+ Authentication
Configuring TACACS+ on the Switch
Configuring the Switch’s Authentication Methods
The 
aaa authentication command configures the access control for console 
port and Telnet access to the switch. That is, for both access methods, 
aaa 
authentication specifies whether to use a TACACS+ server or the switch’s local 
authentication, or (for some secondary scenarios) no authentication (meaning 
that if the primary method fails, authentication is denied). This command also 
reconfigures the number of access attempts to allow in a session if the first 
attempt uses an incorrect username/password pair.
Syntax: aaa authentication
< console | telnet >
Selects either console (serial port) or Telnet access for 
configuration.
< enable | login >
Selects either the Manager (enable) or Operator (login) 
access level.
< local | tacacs | radius >
Selects the type of security access:
local — Authenticates with the Manager and Operator 
password you configure in the switch.
tacacs — Authenticates with a password and other 
data configured on a TACACS+ server.
radius — Authenticates with a password and other 
data configured on a RADIUS server. (Refer to 
“RADIUS Authentication and Accounting” on page 
5-1.
)
[< local | none >]
If the primary authentication method fails, determines 
whether to use the local password as a secondary method 
or to disallow access.
aaa authentication num-attempts < 1-10 >
Specifies the maximum number of login attempts allowed in 
the current session. Default: 3
