启运完毕后将路由器配置DOWN下后更改密码后再导入
忽略配置清除密码再导入配置步骤
1、重新配置路由器的以太网口地址
[Router-Ethernet1]ip address 192.168.10.1 255.255.255.0
2、保证PC与路由器的以太网口能够互通
3、在路由器上配置一个FTP帐号用来从PC中DOWN配置
[Router]local-user ftp password sim ftp ftp-directory flash:/
4、启动路由器上的FTP服务
[Router]ftp-server enable
4、PC的运行栏中输入CMD
FTP 192.168.10.1
输入用户名ftp密码ftp
hash
lcd c:\ 指定下载后的配置文件目录
get config
然后用写字本或记事本打开更改密码后再put上去
注意:上传以后不需要再保存配置,若再SAVE配置,则上传的配置会被覆盖。
总结:BOOTROM 5.28/7.03/7.05/7.06/9.03/9.05/9.06/9.07清除密码的方式基本上是一样的,不外乎是 Clear application password或 是 Start up and ignore configuration
