Enable Policy Lookup
To enable policy lookup through AAA, follow these steps, beginning in global configuration mode.
SUMMARY STEPS
1. aaa new-model
2. aaa authentication login {default | list-name} method1 [method2...]
3. aaa authorization {network | exec | commands level | reverse-access | configuration} {default |
list-name} [method1 [method2...]]
4. username name {nopassword | password password | password encryption-type
encrypted-password}
DETAILED STEPS
Command or Action Purpose
Step 1
aaa new-model
Example:
Router(config)# aaa new-model
Router(config)#
Enables the AAA access control model.
Step 2
aaa authentication login {default | list-name}
method1 [method2...]
Example:
Router(config)# aaa authentication login
rtr-remote local
Router(config)#
Specifies AAA authentication of selected users at
login, and specifies the method used.
This example uses a local authentication database.
You could also use a RADIUS server for this. For
details, see Cisco IOS Security Configuration
Guide: Securing User Services, Release 2.4T and
Cisco IOS Security Command Reference.
Step 3
aaa authorization {network | exec | commands
level | reverse-access | configuration} {default |
list-name} [method1 [method2...]]
Example:
Router(config)# aaa authorization network
rtr-remote local
Router(config)#
Specifies AAA authorization of all
network-related service requests, including PPP,
and specifies the method of authorization.
This example uses a local authorization database.
You could also use a RADIUS server for this. For
details, see Cisco IOS Security Configuration
Guide: Securing User Services, Release 2.4T and
Cisco IOS Security Command Reference.
Step 4
username name {nopassword | password
password | password encryption-type
encrypted-password}
Example:
Router(config)# username username1 password
0 password1
Router(config)#
Establishes a username-based authentication
