Configuration Tasks DETAILED STEPS Step 1 enable 26 Stateful Switchover or no boot system tftp filename [ip-address] 5. boot system flash [flash-fs:][partition-number:][filename] or boot system tftp filename [ip-address] 6. config-register value 7. exit 8. copy running-config startup-config 9. reload Command Purpose Example: Router> enable Step 2 show version Example: Router# show version Step 3 configure terminal Example: Router# configure terminal Step 4 no boot system flash [flash-fs:][partition-number:][filename] or no boot system tftp filename [ip-address] Example: Router(config)# no boot system flash or Router(config)# no boot system tftp://192.168.7.24/cs3-rx.90-1 Enables privileged EXEC mode. • Enter your password if prompted. Stateful Switchover Obtains the current configuration register setting. Enters global configuration mode. (Optional) Clears any existing system Flash or TFTP boot image specification.
Stateful Switchover Step 5 boot system flash [flash-fs:][partition-number:][filename] For the Cisco 10000 series only: boot system tftp filename [ip-address] Example: Router(config)# boot system flash or Router(config)# boot system tftp://192.168.7.24/cs3-rx.90-1 Step 6 config-register value Step 7 exit Example: Router(config)# config-register 0x2102 Example: Router(config)# exit Step 8 copy running-config startup-config Step 9 reload Command Purpose Example: Router# copy running-config startup-config Example: Router# reload Configuring SSO Following the reload, each RP is in its default mode: • The Cisco 7304 series router reboots in SSO mode. • The Cisco 7500 series router reboots in HSA mode. • The Cisco 10000 series Internet router reboots in SSO mode. • The Cisco 12000 series Internet router reboots in RPR mode. Stateful Switchover 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 to reflect the way in which you want to load a 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. 27
