pixfirewall(config)# interface e0 pixfirewall(config-if)# ip address 218.1.1.1 255.255.255.0 pixfirewall(config-if)# no shutdown pixfirewall(config-if)# nameif outside INFO: Security level for "outside" set to 0 by default. pixfirewall(config-if)# interface e1 pixfirewall(config-if)# ip address 172.16.254.1 255.255.255.0 pixfirewall(config-if)# no shutdown pixfirewall(config-if)# nameif inside INFO: Security level for "inside" set to 100 by default. pixfirewall(config-if)# exit pixfirewall(config)# nat (inside) 1 172.16.254.0 255.255.255.0 pixfirewall(config)# global (outside) 1 interface

　　第二步，配置AAA服务器参数。

pixfirewall(config)# aaa-server test protocol radius pixfirewall(config)# aaa-server test (inside) host 172.16.254.10 cisco

　　第三步，配置AAA认证。

pixfirewall(config)# access-list access-internet extended permit ip any any pixfirewall(config)# aaa authentication match access-internet inside test pixfirewall(config)# access-list access-internet extended permit ip any any pixfirewall(config)# aaa authentication match access-internet inside test

　　第四步，测试。
