Cisco路由器上配置3A认证的故障调试

AAA故障与调试

在路由器的AAA配置中，是否认证，认证、授权及记账情况如何，在配置阶段少不了调试，在出现故障时，借助调试信息能很好地定位故障点。

1．Debug AAA Authentication命令

使用Debug AAA Authentication命令来调试一个EXEC登录过程，采用的Rongxin的认证方法列表，使用TACACS+认证协议，系统通过发送GETUSER和GETPASS来提示输入用户名和密码，最优通过认证（PASS）的过程。

Router# debug aaa authentication

AAA Authentication debugging is on

rem_addr='192.168.1.102' authen_type=ASCII service=ENABLE priv=15 vrf= （id=0） 

2．Debug AAA Authorization命令

使用Debug AAA Authentication命令来调试认证信息，用户名为“user1”属性值被授权，最后端口授权通过。

Router# debug aaa authentication r

*Mar  1 01:35:18.427: AAA/BIND（00000016）: Bind i/f

rem_addr='192.168.1.102' authen_type=ASCII service=ENABLE priv=15 vrf= （id=0）

3．Debug AAA Accounting命令

使用Debug AAA Accounting命令来调试记账信息，通过CALL START和CALL STOP 来按时计费，使用Debug Tacacs 和Debug RADIUS可得到基于协议级别的更多信息，也可以使用Show accounting来查看记账的记录。

Router# debug aaa accounting
