简介
本文档介绍在XE-SDWAN上恢复口令的过程。
先决条件
要求
本文档没有任何特定的要求。
使用的组件
本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您的网络处于活动状态，请确保您了解所有命令的潜在影响。
问题
在XE-SDWAN（16.10.3版以后）中，由于安全原因，存在默认的一次性管理员密码，用户可轻易忽略该密码，并且可能进入用户锁定状态。
在未建立与vManage控制器的控制连接的情况下，这在初始路由器设置期间尤其危险；您不能简单地附加设置了用户名和密码的新模板。
本文详细介绍了如何进行恢复。
Username: admin Password: Router#
Sep 23 20:36:03.133: SDWAN INFO: WARNING: Please configure a new username and password; one-time user admin is removed.
这是使用默认admin/admin凭证登录后控制台上的新消息。
注意：此过程会清除当前配置，因此请尽可能备份配置，然后继续操作。
解决方案
这是一个设备在忽略控制台日志中的一次性密码消息时如何被锁定的示例。

步骤1:使用以下步骤启动流程
- 关闭并重新启动路由器，然后强制其进入中断序列的ROMmon模式(ctrl+break， ctrl+c)。
- 将配置寄存器更改为0xA102或0x8000。
注：我们建议0xA102，因为它不易出现用户错误。例如，如果错误地将配置寄存器设置为0x800而不是0x8000（两个零而不是三个），则控制台波特率设置为4800而不是配置旁路。有关配置寄存器的详细信息，请参阅https://www.cisco.com/c/en/us/support/docs/routers/10000-series-routers/50421-config-register-use.html
注意：在Cisco IOS® XE软件中，无法使用0x2142配置寄存器执行配置旁路，因为Cisco IOS® XE SD-WAN软件以不同方式在闪存上的配置数据库(CDB)中存储配置。 从Cisco IOS® XE SD-WAN软件16.10.1开始，位15可设置为1以绕过配置，因此配置寄存器例如0xA102。这是位15 at(0x8000)与默认寄存器0x2102的十六进制值组合的结果。
3.重置复选框（检查命令的输出）。

第三步：使用默认管理员凭证登录。

Configuration register is 0x8000
第四步：这是强制步骤。
- 将配置寄存器改回0x2102并执行sdwan软件重置。这将清除存在的所有配置。
- 在此步骤中，路由器将重新启动，并使用packages.conf配置文件中指定的软件进行启动。

第五步：现在，再次提示您输入一次性管理员凭证。执行完此步骤后，不要忘记更改默认密码。建议同时添加其他用户。如果您错过此步骤而被锁定，则需要再次重复所有步骤。
