光纤交换机密码重置

往往我们会忘记曾经设置过的密码，导致无法正常登陆设备，因此需要重置密码，博科光纤交换机的默认用户名是admin，默认密码是password。但博科交换机是没有reset按钮的，必须通过console线连接通过命令重置。
博科300的os是用的linux 2.6的核心，最高权限的管理帐号是root。重置交换机密码就是用这个帐号。
swd77 login: root
Password: fibranne
使用该帐号登陆后会出现下面的信息：
Disclaimer for Root and Factory Accounts Usage!
This Fibre Channel switch is equipped with Root and Factory accounts
that are intended for diagnostics and debugging purposes solely by
the Equipment vendors trained engineers. Improper use of the
functionality made available through the Root or Factory account could
cause significant harm and disruption to the operation of the SAN fabric.
Your use of the functionality made available through the Root or Factory

explicitly indicates your agreement to the terms of this disclaimer.
Please change passwords for switch default accounts now.
Use Control-C to exit or press Enter key to proceed.
这里用Control-C结束就行了，如果回车会让分别设置各个帐号的密码，出现如下信息：
Warning: Access to the Root and Factory accounts may be required for
proper support of the switch. Please ensure the Root and Factory
passwords are documented in a secure location. Recovery of a lost Root
or Factory password will result in fabric downtime.

登陆后是用passwddefault命令恢复出厂密码
swd77:root> passwddefault
Password policies are already set to default.
All account passwords have been successfully set to factory default.
swd77:root>
至此已经恢复了交换机出厂密码设置，立即可以用默认用户名admin，默认密码password登陆设备进行管理和配置了。
