How to factory reset IOS-XR?

Factory Resetting Cisco IOS XR Devices

Cisco IOS XR is a powerful, feature-rich, and highly secure operating system used to power the majority of the world’s core network routers. It is designed for resiliency, scalability, and high performance. As with any router, it is important to understand how to perform a factory reset on an IOS XR device in order to restore the router to its original configuration.

The first step in performing a factory reset on an IOS XR device is to connect via console. This can be done via the console port on the router or over a network connection such as SSH or Telnet. Once connected, it is necessary to enter privileged mode by typing the enable command.

Once in privileged mode, the command to perform a factory reset is “reset configuration”. This command will erase all the current configuration and reset the router to its factory defaults. It is important to note that this command will not reboot the router; it will only reset the configuration.

Once the reset configuration command has been issued, the router will prompt for confirmation. The user should enter “yes” to confirm the reset. Once the reset is complete, the router will be reset to its factory defaults and all current configuration will be erased. It is important to note that this will not reset the router’s passwords, so the user should reset these manually.

If the user is unable to access the router via the console port, the reset configuration command can also be issued over the network. This can be done using the “reset configuration” command in the CLI of the router. Again, the user will be prompted to confirm the reset.

It is important to note that the reset configuration command will not reset the router’s boot configuration. If the user needs to reset the boot configuration, they should use the “reset boot-config” command instead. This will restore the router’s boot configuration to its factory defaults.

Finally, it is important to remember that a factory reset will erase all current configuration from the router. As such, it is important to back up any configuration before performing a factory reset. This can be done by using the “copy running-config startup-config” command to save the current configuration to the router’s internal memory.

In conclusion, a factory reset on an IOS XR device can be performed by connecting via console or over the network and issuing the “reset configuration” command. It is important to remember to back up any configuration before performing a reset and to also reset any passwords manually. Finally, if the boot configuration needs to be reset, the “reset boot-config” command should be used instead.
