DETAILED STEPS
Purpose Command or Action
Enables privileged EXEC mode. Device> enable Step 1
• Enter your password if prompted.
Enters global configuration mode. Device# configure terminal Step 2
Enables DNIS mapping. Device (config)#
aaa dnis map enable
Step 3
Maps a DNIS number to a defined AAA server group; the
servers in this server group are being used for authentication. Router(config)# aaa dnis map dnis-number
authentication ppp group server-group-name
Step 4
Maps a DNIS number to a defined AAA server group; the
servers in this server group are being used for accounting. Router(config)# aaa dnis map dnis-number
accounting network [ none | start-stop | stop-only ]
group server-group-name
Step 5
Configuration Options
You can configure the switch to use a single server or AAA server groups to group existing server hosts for
authentication. You can group servers to select a subset of the configured server hosts and use them for a
particular service. The server group is used with a global server-host list and contains the list of IP addresses
of the selected server hosts.
Login Authentication
A method list describes the sequence and authentication methods to be queried to authenticate a user. You
can designate one or more security protocols to be used for authentication, thus ensuring a backup system for
authentication in case the initial method fails. The software uses the first method listed to authenticate users;
if that method fails to respond, the software selects the next authentication method in the method list. This
process continues until there is successful communication with a listed authentication method or until all
defined methods are exhausted. If authentication fails at any point in this cycle
— meaning that the security
server or local username database responds by denying the user access
—
the authentication process stops, and
no other authentication methods are attempted.
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.
