Step 4
Router(config)# aaa authorization network 
list-name method1 [method2...]
Sets parameters that restrict user access to a network.
The list-name argument is a character string used to name the list 
of authentication methods tried when a user logs in.
The method1[method2...] argument is at least one of the following 
keywords:
  • group radius—Uses the list of all RADIUS servers for 
authentication.
  • group group-name—Uses a subset of RADIUS servers for 
authentication as defined by the aaa group server radius 
command.
  • if-authenticated—Succeeds if user has been successfully 
authenticated.
  • local—Uses the local username database for authentication.
  • none—Uses no authentication.
Step 5
Router(config)# aaa accounting {system 
default [vrf vrf-name] | network {default 
| none | start-stop | stop-only | 
wait-start} group group-name
Enables AAA accounting of requested services for billing or 
security purposes when you use RADIUS.
The system default keyword performs accounting for all 
system-level events not associated with users, such as reloads.
The vrf vrf-name keyword and argument specify a VRF 
configuration.
The network keyword runs accounting for all network-related 
service requests.
The default keyword specifies the default accounting list:
  • none—No accounting.
  • start-stop—Record stop and start without waiting.
  • stop-only—Record stop when service terminates.
  • wait-start—Record stop and start after start-record commit.
The group group-name keyword and argument use a subset of 
RADIUS servers for accounting as defined by the server group 
group-name.
Step 6
Router(config)# aaa accounting 
delay-start vrf vrf-name
Delays generation of the start accounting records until the user 
IP
 address is established.
The vrf vrf-name keyword and argument enables the specification 
on a per VRF basis.
Step 7
Router(config)# aaa accounting send 
stop-record authentication failure vrf 
vrf-name
Generates accounting stop records for users who fail to 
authenticate at login or during session negotiation.
The vrf vrf-name keyword and argument enables the specification 
on a per VRF basis.
