Controlling Switch Access with TACACS+
To secure the switch for HTTP access by using AAA methods, you must configure the switch with the
Note
ip http authentication aaa global configuration command. Configuring AAA authentication does not
secure the switch for HTTP access by using AAA methods.
For more information about the ip http authentication command, see the Cisco IOS Security Command
Reference, Release 12.2 from the Cisco.com page under Documentation > Cisco IOS Software > 12.2
Mainline > Command References.
Configuring TACACS+ Authorization for Privileged EXEC Access and Network Services
AAA authorization limits the services available to a user. When AAA authorization is enabled, the
switch uses information retrieved from the user's profile, which is located either in the local user
database or on the security server, to configure the user's session. The user is granted access to a
requested service only if the information in the user profile allows it.
You can use the aaa authorization global configuration command with the tacacs+ keyword to set
parameters that restrict a user's network access to privileged EXEC mode.
The aaa authorization exec tacacs+ local command sets these authorization parameters:
•
•
Authorization is bypassed for authenticated users who log in through the CLI even if authorization has
Note
been configured.
Beginning in privileged EXEC mode, follow these steps to specify TACACS+ authorization for
privileged EXEC access and network services:
Command
Step 1
configure terminal
Step 2
aaa authorization network tacacs+
Step 3
aaa authorization exec tacacs+
Step 4
end
Step 5
show running-config
Step 6
copy running-config startup-config
To disable authorization, use the no aaa authorization {network | exec} method1 global configuration
command.
