Week04_配置本地和基于服务器的AAA

本次实验主要完成AAA 服务器（Server）的安装与调试，客户端（Client）配置，验证以及AAA 排错的过程，包括现场完成对SPOTOTM 设备中心Rack 机架终端服务器的配置

3.6.1.2 Packet Tracer - 在Cisco路由器上配置AAA认证在本实验任务中，你将使用Packet Tracer模拟环境来在Cisco路由器上实现AAA（Authentication, Authorization, and Accounting）认证。AAA是一种网络安全框架，它为网络设备提供了集中、安全的用户访问控制机制。具体步骤可能包括但不限于以下内容： 1. **创建本地用户数据库**：首先在路由器上建立本地用户数据库，包含用户名、密码以及可选的权限级别或其他属性。 2. **启用AAA**：在全局配置模式下启用AAA服务，并指定AAA使用的身份验证、授权和记账方法。 3. **配置AAA认证**： - 配置路由器使用本地数据库进行身份验证，例如通过`aaa new-model`命令启用AAA并设置`aaa authentication login local`。 - 可能还需要配置其他身份验证方式，如TACACS+或RADIUS服务器。 4. **配置AAA授权**：定义不同用户组或用户的授权策略，确定他

实验报告包含详细的实验截图和命令 Task 1: Configure Local AAA Authentication for Console Access on R1 Step 1. Test connectivity. · Ping from PC-A to PC-B. · Ping from PC-A to PC-C. · Ping from PC-B to PC-C. Step 2. Configure a local username on R1. Configure a username of Admin1 and secret password of admin1pa55. Step 3. Configure local AAA authentication for console access on R1. nable AAA on R1 and configure AAA authentication for console login to use the local database. Step 4. Configure the line console to use the defined AAA authentication method. Enable AAA on R1 and configure AAA authentication for console login to use the default method list. Step 5. Verify the AAA authentication method. Verify the user EXEC login using the local database. Task 2: Configure Local AAA Authentication for VTY Lines on R1 Step 1. Configure a named list AAA authentication method for VTY lines on R1. Configure a named list called TELNET-LOGIN to authenticate logins using local AAA. Step 2. Configure the VTY lines to use the defined AAA authentication method. Configure the VTY lines to use the named AAA method. Step 3. Verify the AAA authentication method. Verify the Telnet configuration. From the command prompt of PC-A, Telnet to R1. Task 3: Configure Server-Based AAA Authentication Using TACACS+ on R2 Step 1. Configure a backup local database entry called Admin. For backup purposes, configure a local username of Admin and secret password of adminpa55. Step 2. Verify the TACACS+ Server configuration. 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. Step 3. Configure the TACACS+ server specifics on R2. Configure the AAA TACACS server IP address and secret key on R2. Step 4. Configure AAA login authentication for console access on R2. Enable AAA on R2 and configure all logins to authenticate using the AAA TACACS+ server and if not available, then use the local database. Step 5. Configure the line console to use the defined AAA authentication method. Configure AAA authentication for console login to use the default AAA authentication method. Step 6. Verify the AAA authentication method. Verify the user EXEC login using the AAA TACACS+ server. Task 4: Configure Server-Based AAA Authentication Using RADIUS on R3 Step 1. Configure a backup local database entry called Admin. For backup purposes, configure a local username of Admin and secret password of adminpa55. Step 2. Verify the RADIUS Server configuration. 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. Step 3. Configure the RADIUS server specifics on R3. Configure the AAA RADIUS server IP address and secret key on R3. Step 4. Configure AAA login authentication for console access on R3. Enable AAA on R3 and configure all logins to authenticate using the AAA RADIUS server and if not available, then use the local database. Step 5. Configure the line console to use the defined AAA authentication method. Configure AAA authentication for console login to use the default AAA authentication method. Step 6. Verify the AAA authentication method. Verify the user EXEC login using the AAA TACACS+ server. Step 7. Check results.
