初始配置
Switch
Conf t
Int f 0/1
No sw
Ip ad 10.1.1.2 255.255.255.0
End
Router
Conf t
Int e 0
Ip ad 10.1.1.1 255.255.255.0
No shut
Server IP address 10.1.2.1/24
测试
sw1#ping 10.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds:
.!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 12/52/116 ms
1， 在Router做TELNET 命令，访问Switch
Switch
Conf t
No service password-recovey
Enable secret ccie
Line vty 0 15
Login
Password ccie
End
在Router上校验
R1#telnet 10.1.1.2
Trying 10.1.1.2 ... Open
User Access Verification
Password: 被隐藏
sw1>en
Password: 被隐藏
sw1# 进入交换机特权模式
sw1#quit
[Connection to 10.1.1.2 closed by foreign host]
R1# 回到Router
2， 配置username和password对
这个配置使username 和password存储在本地交换机中，在switch上配置
Conf t
Username cisco password ccie
Line vty 0 15
Login local
End
在Router上校验
R1#telnet 10.1.1.2
Trying 10.1.1.2 ... Open
User Access Verification
Username: cisco
Password: 被隐藏
sw1>en
Password: 被隐藏
sw1#quit
[Connection to 10.1.1.2 closed by foreign host]
R1#
3， 配置多种特权等级
在交换机上配置用户，并对用户单独进行授权
Conf t
Username cisco privilege 2 password 0 ccie
在Router上校验
R1#telnet 10.1.1.2
Trying 10.1.1.2 ... Open
User Access Verification
Username: cisco
Password:
sw1#conf t
^
% Invalid input detected at '^' marker.
为什么会出错呢？因为我们没有对此用户的访问进行授权，现在交换机上进一步配置
Privilege exec level 2 conf t
Privilege configure level 2 interface
Privilege interface level 2 no switchport
Privilege interface level 2 ip address
Privilege interface level 2 no shut
在Router上校验
sw1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
sw1(config)#int f 0/2
sw1(config-if)#no sw
sw1(config-if)#ip ad 10.1.2.2 255.255.255.0
sw1(config-if)#shut
sw1(config-if)#no shut
sw1(config-if)#^Z
sw1#quit
[Connection to 10.1.1.2 closed by foreign host]
R1#
4， 在交换机上配置本地Authentication和Authorization服务，在本地交换机上AAA验证
Conf t
Aaa new-model
Aaa authentication login default local
Aaa authorization exec default local
Aaa authorization network default local
Username cisco password ccie
在Router上校验
Username: cisco
Password:
sw1>en
Password:
sw1#config t
Enter configuration commands, one per line. End with CNTL/Z.
sw1(config)#^Z
sw1#quit
[Connection to 10.1.1.2 closed by foreign host]
R1#
下面来讨论TACACS+ SERVER和RADIUS SERVER的验证授权和统计。

Line vtp 0 15
Login authentication default
Exit
3，配置RADIUS的EXEC访问和network授权
Aaa authorization network default group radius
Aaa authorization exec default group radius
3， 配置RADIUS的统计
Aaa accounting network default start-stop group radius
Aaa accounting exec default start-stop group radius
