Enabling High Availability Features

Fast Software Upgrade Example

Thefollowing example show a Fast Software Upgrade performed on a Cisco 7507 router with an active
RSP in slot 2 and a standby RSP installed in slot 3.
Router# copy tftp slot0:rsp-pv-mz
Router# copy tftp slaveslot0:rsp-pv-mz
Router# configure terminal
Router(config)# hw-module slot 2 image slot0:rsp-pv-mz
Router(config)# hw-module slot 3 image slot0:rsp-pv-mz
Router(config)# end
Router# hw-module sec-cpu reset
Router# copy running-config startup-config
Router# redundancy force-switchover
Configuring SLCR
TheCisco 7500 SLCR feature is disabled by default. Therefore, the process for disabling this feature is
only necessary if the Cisco 7500 SLCR feature has been enabled by the user on the Cisco 7500 series
router.

Enabling SLCR

To enable the Cisco 7500 Single Line Card Reload (SLCR) feature, use theservice
single-slot-reload-enable global configuration command on the Cisco 7500 series router.
Step6 Router(config)#slave auto-sync config (Optional) Turns on automatic synchronization of
configurationfiles. Use this command to ensure that
the active and standby RSPs contain the same
configuration files.
Step7 Router(config)#end Exits global configuration mode and returns you to
privileged EXEC configuration mode.
Step8 Router# copy running-config startup-config Saves the configuration changes to your startup
configurationin NVRAM so the router boots with the
configuration you have entered.
Step9 Router# hw-module sec-cpu reset Resets and reloads the standby RSP with the
specified CiscoIOS image and executes the image.
Note If you do not specify a Cisco IOS image in
Step 2, this command loads and executesthe
bundled default IOS standby image. The
system then operates in HSA mode.
Step10 Router# redundancy force-switchover Forces a switchover to the standby RSP.
1. Before you copy a file to Flash memory, be sure there is ample space available in Flash memory. Compare the size of the file you are copying to the
amountof available Flash memory shown. If the space available is less than the space required by the file you will copy, the copy process will continue,
but the entire file will not be copied into Flash memory.
Command Purpose
Router(config)#service single-slot-reload-enable Enables single line card reloading for all of the line cards in the
Cisco 7500 series router.
