路由器的telnet是使用的虚拟通道，路由器还有很多的接口IP，所以对路由器的物理接口IP或逻辑接口IP做*是不明智的。只需要使用一条标准的访问控制列表就可以设置允许那些IP来telnet本路由器了。实例：

Router(config)# access-list 1 permit 192.89.55.0 0.0.0.255
Router(config)# line vty 0 4
Router(config-line)# access-class 1 in

只允许网络192.89.55.0 内的主机连接路由器的 vty 通道
该例中要先设置好vty的口令才能检测。设置vty口令过程如下：
Router(config)# line vty 0 4
Router(config-line)#login
Router(config-line)#password xxx
