juniper防火墙之恢复出厂默认设置.docx

juniper防火墙之恢复出厂默认设置用过Juniper产品的人都应该知道一点，Juniper产品密码忘了的话是一件很痛苦的事，为什么这么说呢？下来就来听我给大家讲讲嘛！密码丢失是无法恢复的，那么我们就只有通过恢复出厂默认设置的方法来重新获得管理权限 （原来配置的参数、证书等都将被删除）。有两种办法恢复出厂默认配置：1、在Console模式下，用设备的序列号作用用户名/密码进行登录。成功后系统出现警告提示，将擦去现有配置，确认后系统开始恢复默认配置，随后重启。整个过程约3分钟。那么我们如何获得这个序列号呢？要获得这个序列号的办法有两种，第一种就是在产品的背后有一个序列号。第二种办法就是通过输入“get sys”来获取。这里我们先来看看Juniper防火墙的启动过程：NetScreen NS-5GT Boot Loader Version 2.1.0 (Checksum: 61D07DA5) Copyright (c) 1997-2003 NetScreen Technologies, Inc.
