近期老是有网友在网上问我，3COM交换机如何配置，由于问得多了，我估计这个交换机性价比较高，而且手上刚好有一款3COM 4200 3C17300A，所以我特将他的配置代码保存下来给大家使用！
使用方法:
1、请将下面的代码保存到一个文件里面：如3comvlan
2、用COM线进入3COm配置
3、点restore命令，还原这个文件到交换机，重启后即可
配置文件说明：
1、恢复后，IP为192.168.1.254，可通过Telnet来连接
2、恢复后，用户名为admin，密码admin或者空，忘记了
3、恢复后，1-25口分别为vlan 1-25，26口接WAYOS、HZZ、ROS的WAN口网卡
下面的这个交换机图片，其他的可以大同小异：
请将下面的代码复制到文件，下面开始到结束，所有代码都是：
#<header>3Com_DEVICE</header>
#<key>3C17300M1:</key>
