Configuration Rollback
Note: This feature is supported only on 7210 SAS-R6 devices.
The Configuration Rollback feature provides the ability to “undo” configuration and reverts back
to previous router configuration states while minimizing impacts to services.
This feature gives the operator better control and visibility over the router configurations and
reduces operational risk while increasing flexibility and providing powerful recovery options.
Configuration Rollback is useful in cases where configuration changes are made, but the operator
later decides not to keep the changes (for example, experimentation or when problems are
identified in the configuration during actual network operation).
The advantages of this feature are as follows:
• Changes made to router configuration is performed with minimal impact on services
being provided by 7210 SAS by not having to reboot the router.
• No impact in areas of configuration that did not change.
With this rollback feature, the operator can smoothly revert to previous configurations.
Configuration parameters that changed (or items that changed configuration have dependencies
on) are first removed (revert to default), and the previous values are then restored (can be briefly
service impacting in changed areas).
A history of changes is preserved (checkpoint ids) that allows rollback to different points, as well
as examination of changes made as shown in Figure 1:
