假如交换机的login密码忘记了咋办啊?
别急别急,只要你有PC,有类似超级终端(Hyper Terminal)这样是终端程序,连接到交换机的console口,那么密码的恢复就简单了。
1.对于Catalyst 2900/3500XL系列来说:
拔下交换机的电源线,然后按住交换机的Mode按钮,再重新插上交换机的电源线.直到端口Port 1x的LED熄灭之后释放Mode按钮。
就这么简单,别告诉我你不知道Mode按钮在哪啊。
2.对于Catalyst 2940/2950L系列来说:
拔下交换机的电源线,然后按住交换机的Mode按钮,再重新插上交换机的电源线.直到STAT的LED熄灭之后释放Mode按钮。
3.对于Catalyst 2955系列来说:
Catalyst 2955没有没有外部的Mode按钮,因此就不能使用之前的那种方法来进行密码恢复.在交换机启动时,对于Windows系列的PC,按下Ctrl+Break键;对于UNIX系列的工作站,按下Ctrl+C.如下:
