Context admin>rollback
Description This command initiates a configuration rollback revert operation that will return the configuration state
of the node to a previously saved checkpoint. The rollback revert minimizes impacts to running
services. There are no impacts in areas of configuration that did not change since the checkpoint.
Configuration parameters that changed (or items on which changed configuration have dependencies)
are first removed (revert to default) and the previous values are then restored (can be briefly service
impacting in changed areas).
Parameters latest-rb — Specifies the most recently created rollback checkpoint (corresponds to the file-url.rb
checkpoint-id — Indicates the configuration to return to (which rollback checkpoint file to use).
rescue — Revert to the rescue checkpoint.
now — Forces a rollback revert without any interactive confirmations (assumes 'y' for any
save (rollback)
Syntax save [rescue] [comment comment-string]
Context admin>rollback
Description If the optional rescue keyword is not used, this command saves a rollback checkpoint at the location
and with the filename specified by the rollback-location with a suffix of .rb. The previously saved
checkpoints will have their suffixes incremented by one (.rb.1 becomes .rb.2, etc). If there are already
as many checkpoint files as the maximum number supported, then the last checkpoint file is deleted.
If the rescue keyword is used, then this command saves the current operational configuration as a
rescue configuration at the location and with the filename specified by the rescue location. The
filename will have the suffix .rc appended.
Default none
Parameters

Checkpoint-id of 1 corresponds to the file-url.rb.1 rollback checkpoint file. The higher the id,
the older the checkpoint. Max is the highest rollback checkpoint supported or configured.
Values 1—max, where max is the number of configured checkpoints
minus 1 (since, for example, the 10th checkpoint has an id of 9)
