如果再加上每一步的说明就更完美更香了。
谢谢楼主分享。

设备启动之后应该用 copy flash:config.old system:running-config
不执行这个copy的话,按照上面的配置wr之后整个设备只有一个enable密码设置
当然,如果单纯的想清空配置,可以直接在switch:模式下 delete flash:config.text 、 delete flash:vlan.dat
!
----
补充一下遗漏的点:
1、先按住mode 键然后再加电,大约10-15秒后松开能进入switch:模式,部分机型时间可能会久一点,可以看console的输出
2.如果想保留之前配置,仅修改console密码enable密码或vty的密码,需要将原有配置文件rename
flash_init
rename flash:config.text flash:config.old
boot
(swith: 模式下命令无法补全,需手动敲完整)
设备启动之后先进特权模式,然后执行以下操作
copy flash:config.old system:running-config
conf t
enable sec cisco
!
line con 0
no password //需要设置console密码执行password xxx 即可 xxx为自定义密码
!
line vty 0 4
password cisco
!
最后通过wr或者copy running-config startup-config 保存最新配置
3. 如果仅想清空当前设备配置,可将上面中的rename 命令更改为delete flash:config.text / delete flash:vlan.dat 执行完成之后boot启动即可

补充的很及时,这个是试验机演示如何跳过密码的文件,没有其他配置

对,如果再加上每一步的说明就更完美更香了,而且是全系列吗?还是只是交换机?
谢谢楼主分享。
