所述线卡单元接收到telnet报文之后，对所述报文进行解析，从而确定将所述telnet报文上送至所述路由设备的CPU，或者将所述telnet报文转发至与其级联的其它下一级路由设备。
当所述telnet报文为访问设备内部控制面的telnet报文时，所述线卡单元将所述telnet报文上送至本地路由设备的CPU进行处理；当所述telnet报文为与其它路由设备控制面进行通信的telnet报文时，所述线卡单元将所述telnet报文转发至其它路由设备；所述telnet报文中将封装待转发的其它路由设备的IP地址，线卡单元根据所述IP地址实现转发即可。
通过上述方案，用户可以实现对所述路由设备内部控制面的访问，从 而实现对本地路由设备的管理；也可以实现与所述路由设备相连接的其它路由设备之间的通信，从而实现对其它路由设备的管理。
步骤101之前，需要预先配置所述逻辑端口的网际协议(IP，InternetProtocol)地址，则用户可以远程登陆所述IP地址，即，使用telnet命令远程登陆所述IP地址，通过这一操作，将发送telnet报文至所述逻辑端口；且所述telnet报文为访问本地设备内部控制面的telnet报文；
当用户希望对其它路由设备进行管理时，只需要使用telnet命令远程登陆相应路由设备的IP地址即可，通过这一操作，也将发送telnet报文至所述逻辑端口，不同的是，所述telnet报文为访问其它路由设备内部控制面的telnet报文，因此，所述telnet报文中需要封装相应路由设备的IP地址。
从以上内容可以看出，通过本发明实施例提供的方法，用户既可以对本地路由设备的内部控制面进行访问，也可以对其它路由设备内部控制面进行访问。而从用户的角度来看，只需要使用telnet命令远程登陆相应IP地址即可轻松访问本地路由设备内部控制面或其它路由设备内部控制面，从而实现对本地路由设备或实现对与本地路由设备相连接的其它路由设备的管理。
而相较于现有技术，一方面来说，本发明实施例提供的设备管理方法，通过第一交换芯片上的逻辑端口接收telnet报文，从而实现对本地路由设备的管理，即，节省了原有的主用主控单元中二层交换芯片上的一个业务口；另一方面来说，本发明实施例提供的方法可以实现一台路由设备和其它路由设备控制面之间的通信，从而使用户可以从本地实现对其它路由设备的管理，而且这种实现并没有借助于三层交换芯片，因此，既实现了原有二层路由设备不具备的功能，又节省了成本。
