如何将Cisco路由器恢复到原始出厂默认设置？

思科作为全球翘楚品牌，其路由器也成为众多企业的首选产品。路由器作为连接不同网络并传输数据的产品，可以根据预定的路由协议决定数据包的传输路径，实现网络之间的数据交换。路由器可以将数据包从源节点传递到目的节点，同时确保数据的安全性和完整性。

思科路由器恢复出厂设置的方式：

思科路由器以其高性能、高可靠性著称，适用于各种规模的网络环境，从家庭网络到企业级网络均能满足。然而，一旦路由器遇到故障，将会给家庭或企业带来不必要的影响和麻烦。

当路由器发生故障时，我们首先可能会想到要尝试重启路由器来修复故障，但是，如果重启无法修复时，我们可以尝试将路由器恢复到原始出厂默认设置。那么，如何将Cisco 路由器恢复到其原始出厂默认设置呢？网度通信工程师给到我们一些基础的设置步骤，需要的朋友建议收藏备用！

有两种主要方法可以将 Cisco 路由器恢复到其原始出厂默认设置。下面将介绍这两种方法。

方法 1

该方法在全局配置模式下使用config-register 0x2102命令。

发出show version命令检查路由器上的配置寄存器。

配置寄存器设置显示在show version命令输出的最后一行，必须设置为0x2102。

Router#show version

Configuration register is 0x2102

如果不是这种情况，请在全局配置模式下输入config-register 0x2102命令一次。

Router#configure terminal

Router(config)#config-register 0x2102

Router(config)#end

Router#

如果再次发出show version命令，则命令输出中的同一行可以将(0x2102 at next reload)附加到当前寄存器设置中。

2. 使用write erase命令清除路由器上的当前启动配置。

3.使用reload命令重新加载路由器。当系统提示save 提示配置时，DO NOT

Router#reload

System configuration has been modified. Save ? [yes/no]: n

Proceed with reload? [confirm]

路由器重新加载后，系统将显示System Configuration对话框。

--- System Configuration Dialog ---

Would you like to enter the initial configuration dialog? [yes/no]:

现在，路由器已重置为原始出厂默认设置。

方法 2

该方法在全局配置模式下使用config-register 0x2142命令。

在全局配置模式下输入config-register 0x2142命令。

Router(config)#config-register 0x2142

这使路由器在下次重新加载时忽略启动配置。如果再次运行show version，则它将（下次重新加载时为0x2142）附加到当前配置寄存器 setting中。

Router#show version
