Figure 4: 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
then 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
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 cause a traffic
interruption.
•
A Rollback will undo any SNMP sets or direct CLI config commands that occurred since
the last checkpoint creation.
•
During the period when an SR-OS node is processing a rollback revert, both CLI
commands (from other users) and SNMP commands will continue to be processed. The
