Configuring the Switch for Local Authentication and Authorization
Configuring the Switch for Local Authentication and
Authorization
You can configure AAA to operate without a server by setting the switch to implement AAA in local
mode. The switch then handles authentication and authorization. No accounting is available in this
configuration.
Beginning in privileged EXEC mode, follow these steps to configure the switch for local AAA:
To disable AAA, use the no aaa new-model global configuration command. To disable authorization,
use the no aaa authorization {network | exec} method1 global configuration command.
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
aaa new-model
Enable AAA.
Step 3
aaa authentication login default local
Set the login authentication to use the local username database. The
default keyword applies the local user database authentication to all
interfaces.
Step 4
aaa authorization exec local
Configure user AAA authorization to determine if the user is allowed to
run an EXEC shell by checking the local database.
Step 5
aaa authorization network local
Configure user AAA authorization for all network-related service
requests.
Step 6
username name [privilege level]
{password encryption-type password}
Enter the local database, and establish a username-based authentication
system.
Repeat this command for each user.
•
For name, specify the user ID as one word. Spaces and quotation
marks are not allowed.
•
(Optional) For level, specify the privilege level the user has after
gaining access. The range is 0 to 15. Level 15 gives privileged EXEC
mode access. Level 0 gives user EXEC mode access.
•
For encryption-type, enter 0 to specify that an unencrypted password
follows. Enter 7 to specify that a hidden password follows.
•
For password, specify the password the user must enter to gain access
to the switch. The password must be from 1 to 25 characters, can
contain embedded spaces, and must be the last option specified in the
username command.
Step 7
end
Return to privileged EXEC mode.
Step 8
show running-config
Verify your entries.
Step 9
copy running-config startup-config
(Optional) Save your entries in the configuration file.
