CATALYST 2900,3500XL的密码恢复:
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-_-#
三.CATALYST 2940,2950L的密码恢复:
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.
四.CATALYST 2955的密码恢复:
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:
