Configuration Tasks
Specifies the filename of an image stored in Flash
memory or on a TFTP server.
The Cisco 10000 series Internet router is the only
networking device capable of being configured to
boot from a TFTP server.
Modifies the existing configuration register setting

system image.
• value—0x0 to 0xFFFF
Exits configuration mode and returns the router to
privileged EXEC mode.
Saves the configuration changes to the startup
configuration file.
Reboots both RPs on the device to ensure that
changes to the configuration take effect.
Note Cisco 7304 routers and Cisco 10000 series Internet routers operate in SSO mode by default after
reloading the same version of SSO-aware images on the device. No configuration is necessary.
