Figure 2: Configuration rollback
• A rollback revert does not affect the currently stored rollback checkpoint files (no deletions or
renumbering). This means that if an operator issues a ‟rollback revert 3” and issues a ‟rollback-save”,
the resulting rollback checkpoint files ‟file-url.rb” and ‟file-url.rb.4” will contain the same rollback state/
configuration.
• The boot-good-exec or boot-bad-exec are not automatically executed after a rollback.
• Impacts to the running services are minimized during a rollback as follows:
– There is no impact in areas of configuration that did not change, except for some exceptions.
– Configuration parameters that changed (or items that a changed configuration has dependencies on)
are first removed and the previous values are restored (can be briefly service impacting in changed
areas). Some examples are as follows:
• If the SAP ingress policy num-qos-resources value is different in the active configuration and
in comparison to the value in the rollback checkpoint, all the SAPs are deleted and created
