• A rollback revert does not affect the currently stored rollback checkpoint files (no
deletions or renumbering). This means that if an operator issues the command
rollback revert 3 and then issues the rollback-save command, 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 bad-exec are not automatically executed after a rollback.
• impacts to the running services are minimized during a rollback:
→ no impact in areas of configuration that did not change
→ configuration parameters that changed (or items that changed config have
dependencies on) are first removed (revert to default) and the previous values are
then restored (can be briefly service impacting in changed areas). Some
examples are the following:
- If the currently active config contains configure port 5/1/1 dwdm tdcm
dispersion -1000 and the rollback checkpoint contains configure port 5/1/
1 dwdm tdcm dispersion -1010, then the operational dispersion will
transition from -1000, to 0 and then back to -1010 for port 5/1/1 which will
