一、题目环境
实验拓扑
地址规划
实验要点
· Configure a local user account on R1 and authenticate on the console and VTY lines using local AAA.
#在R1上配置本地用户帐户，使用本地AAA在控制台和VTY上进行身份验证。
· Verify local AAA authentication from the R1 console and the PC-A client.
#从R1控制台和PC-A客户端验证本地AAA认证。
· Configure a server-based AAA authentication using TACACS+.
#使用TACACS+配置基于服务器的AAA认证。
· Verify server-based AAA authentication from PC-B client.
#从PC-B客户端验证基于服务器的AAA认证。
· Configure a server-based AAA authentication using RADIUS.
#使用RADIUS配置基于服务器的AAA认证。
· Verify server-based AAA authentication from PC-C client.
#从PC-C客户端验证基于服务器的AAA认证。
二、 配置过程
1-1.Configure a username of Admin1 and secret password of admin1pa55.
//R1设置用户名为Admin1，加密密码admin1pa55(这里题目要求用secret但没给分点，password就给了)
R1(config)#username Admin1 password admin1pa55
1-2. Enable AAA on R1 and configure AAA authentication for console login to use the local database.
//R1上启用AAA，配置AAA认证使用本地数据库
R1(config)#aaa new-model
R1(config)#aaa authentication login default local
1-3. Enable AAA on R1 and configure AAA authentication for console login to use the default method list.
//启用AAA，在console登录配置为默认方法列表
R1(config)#line console 0
R1(config-line)#login authentication default
2-1. Configure a named list called TELNET-LOGIN to authenticate logins using local AAA.
//配置一个名为TELNET-LOGIN的命名列表，使用本地AAA对登录进行身份验证。
R1(config)#aaa authentication login TELNET-LOGIN local
2-3. Configure the VTY lines to use the named AAA method.
//配置VTY远程登录用创建的TELNET-LOGIN
R1(config)#line vty 0 4
R1(config-line)#login authentication TELNET-LOGIN
3-1. For backup purposes, configure a local username of Admin and secret password of adminpa55.
//R2由于备份的关系。再创建一个本地用户Admin密码为adminpa55
R2(config)#username Admin password adminpa55
3-2. Select the TACACS+ Server. From the Config tab, click on AAA and notice that there is a Network configuration entry for R2 and a User Setup entry for Admin2.
//点开TACACS服务器，在AAA服务中配置添加R2的客户信息及用户添加Admin2(pka默认已经完成)
3-3. Configure the AAA TACACS server IP address and secret key on R2.
//在R2上配置AAA TACACS服务器IP地址和密钥
R2(config)#tacacs-server host 192.168.2.2
R2(config)#tacacs-server key tacacspa55
3-4. Enable AAA on R2 and configure all logins to authenticate using the AAA TACACS+ server and if not available, then use the local database.
//在R2上启用AAA，并将所有登录配置为使用AAA TACACS+服务器进行身份验证，如果不可用，则使用本地数据库。
R2(config)#aaa new-model
R2(config)#aaa authentication login default group tacacs+ local
3-5. Configure AAA authentication for console login to use the default AAA authentication method.
//为console登录配置AAA身份验证，以使用默认的AAA身份验证方法。
R2(config)#line console 0
R2(config-line)#login authentication default
4-1. For backup purposes, configure a local username of Admin and secret password of adminpa55
//R3配置本地用户Admin和adminpa55的密码，以防配错登录不上
R3(config)#username Admin password adminpa55
4-2. Select the RADIUS Server. From the Config tab, click on AAA and notice that there is a Network configuration entry for R3 and a User Setup entry for Admin3.
//点开RADIUS服务器，在AAA服务中配置添加R3的客户信息及用户添加Admin3(pka默认已经完成)
4-3. Configure the AAA RADIUS server IP address and secret key on R3.
//配置RADIUS服务器IP地址和连接密码
R3(config)#radius-server host 192.168.3.2
R3(config)#radius-server key radiuspa55
4-4. Enable AAA on R3 and configure all logins to authenticate using the AAA RADIUS server and if not available, then use the local database.
//在R3上启用AAA，并将所有登录配置为使用AAA RADIUS服务器进行身份验证，如果不可用，则使用本地数据库
R3(config)#aaa new-model
R3(config)#aaa authentication login default group radius local
4-5. Configure AAA authentication for console login to use the default AAA authentication method.
//为控制台登录配置AAA身份验证，以使用默认的AAA身份验证方法。
R3(config)#line console 0
R3(config-line)#login authentication default
三、验证
