CLI usage
Figure 1: Rollback operation
2.8.1 Feature behavior
The following list describes detailed behavior and CLI usage of the rollback feature:
• 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”, and so on:
file-url.rb <--- latest rollback file
file-url.rb.1
…
file-url.rb.9<--- oldest rollback file
