1,dis cu 这是查看交换机所有配置的命令。你要看的IP应是VLAN的IP

interface vlan 1

ip address 172.16.1.7 255.255.255.0 看到这就是交换机的IP。

像H3C Quaidway 6506这是个三层的交换机，可能会划很多VLAN，所以它会有很我IP。vlan1的IP可以做管理IP(就是做远程配置的IP如：telnet)。如果有多个VLAN IP那非VLAN1的IP就是你所有在那个VLAN里的主机的网关了。

像H3C S1024就是个二层的，一般就会给VLAN1配个IP为以后的方便管理用。

2,一般H3C的都是默认是空的密码。要是有密码那就一定是谁设了，你可以把它解了，方法是：

【第一步 重启交换机，按Ctrl＋B进入BOOTROM菜单】

如果是采用simple方式配置口令，则可以直接显示出密码。

如果是采用cipher方式配置口令，按照以下方法处理：

1)将查看到的配置文件复制保存成一个文本文件。

2)修改该文件中对应帐号的密码“password cipher ;)<01%^&;YGQ=^Q`MAF4<1!!”为类似“password simple aaa”的口令

3)将修改过的脚本，复制粘贴到当前路由器中

4)disp cur确认当前配置和以前的配置一致后，save配置后重新启动系统

5)重启后，就可以通过修改过的帐号口令登录系统
