IOS does support configuration reverting and rollbacks, not in exactly
the same way as IOS-XR/Junos but I always use it when workingon the
production network. Just enable configuration archiving:

conf t
 archive
  path sup-bootdisk:/config-backup-
  maximum 10
  write-memory
  end
wr



conf term lock revert timer 20

%ARCHIVE_DIFF-5-ROLLBK_CNFMD_CHG_BACKUP: Backing up current running
config to sup-bootdisk:/config-backup-Nov-25-2015-23-04-57.804-UTC-166

%ARCHIVE_DIFF-5-ROLLBK_CNFMD_CHG_START_ABSTIMER: User: james.bensley:
Scheduled to rollback to config
sup-bootdisk:/config-backup-Nov-25-2015-23-04-57.804-UTC-166 in 20
minutes


! config changes goes here

end


! Check everythign is OK, then confirm the changes to cancel the rollback timer,
! If I make a big boo boo that cuts me off, the config will roll back
after 20 mins (as above)
! without me confirming it

configure confirm


! Oh no, I haven't made such a big mistake that I've been disconnected
! but actually I do need to rollback

configure replace
sup-bootdisk:/config-backup-Nov-25-2015-23-04-57.804-UTC-166 list

Nov 25 2015 23:25:17.479 UTC:
%ARCHIVE_DIFF-5-ROLLBK_CNFMD_CHG_ROLLBACK_START: Start rolling to:
sup-bootdisk:/config-backup-Nov-25-2015-23-04-57.804-UTC-166
