CLI Usage

2.8.1 Feature Behavior

The following list describes detailed behavior and CLI usage of the rollback feature.
44
• The user can create a rollback checkpoint, and later, return to this checkpoint
with minimal impacts to services by using the following command.
admin>rollback# save [comment comment-string]
comment-string: a 255 character comment associated with the checkpoint
• Rollback checkpoints include all current operationally active configurations:
- changes from direct CLI commands in the configuration branch
- SNMP sets
• Rollback checkpoints do not include BOF configuration information. The BOF
file (and BOF configuration) is not part of a rollback save or rollback. A rollback
does not change any of the BOF configuration. The BOF contains basic
information for the node and does not change frequently (mostly during initial
commissioning of the node).
• A rollback save command can be automatically executed (scheduled, for
example, monthly) using the CRON facility.
• The latest rollback checkpoint file uses a suffix of ".rb". The next latest rollback
checkpoint file has a suffix of ".rb.1", the next oldest has a suffix of "rb.2", etc.:
file-url.rb
file-url.rb.1
...
file-url.rb.9
• When a rollback save [no "-"] is executed, the system shifts the file suffix of all
the previous checkpoints by 1 (new ID= old ID+1). If there are already as many
checkpoint files as the maximum number supported, the last checkpoint file is
deleted.
• The maximum number of rollback checkpoints is configurable and defaults to 10
(the latest files and files 1 through 9, where checkpoint file 9 is deleted during
the next rollback-save).
• The location and name of the rollback checkpoint files are configurable to be
local storage (e.g. compact flash) or remote storage. The file URL must not
contain a suffix (just a path/directory and filename). The suffix for rollback
checkpoint files is .rb and is automatically appended to rollback checkpoint files.
config>system>rollback# rollback-location file-url
• There is no default rollback location. If a location is not specified (or it is cleared
using no rollback-location) and a rollback save is attempted, the rollback
save will fail and return an error message.
