Cisco Router KB Entries
Routing Basics
Routers far away can be safely configured by using a reload command first.
Before any configuration changes are made, issue a reload command to the remote router:
reload in 30 [This command instructs the router to reboot in 30 minutes.]
or reload at 06:00 [This command instructs the router to reboot at 6 'o clock.]
Proceed to configure the router as needed. As long as no configuration changes are saved, the router will revert to its previous configuration when it reloads.
If configuration changes are successful:
reload cancel [will stop the pending reload]
If configuration changes cause a loss of connectivity, the local side can be easily reset to the previous configuration. When the router reloads, connectivity will be restored.

Importing backup images from more than one piece of media from the command line [when media has expired]
Details:
Backups that have expired may be imported by using the bpimport command, provided the media on which the backups reside have not yet been overwritten. Importing images is a two-stage process:
Phase 1
This is performed first and must be done on all media concerned with the backups to be imported (particularly if the backups have spanned over several tapes). This phase recreates catalog entries for the backups by populating the media server's Media Database (mediaDB) with the media IDs, and creating the header files of the backup images in the Image Database. After this phase is completed, the images may be browsed for selection for Phase 2 import.
Phase 2
This may be performed on all media involved in Phase 1, or if there is a selection of backup images desired for importing (after browsing), then the import may be done on the basis of backup IDs. This phase of the import creates the files file(s) of the backup images in the Image Database.
The bpimport commands to perform Phase 1 and 2 operations are as follows:
Phase 1
/usr/openv/netbackup/bin/admincmd/bpimport -create_db_info -id
If browsing for backup images to be imported at Phase 2, use the command:
/usr/openv/netbackup/bin/admincmd/bpimport -PM
Once the backup IDs to import have been chosen, they can be listed in a file referred to as the "Bidfile" for use in Phase 2. If all the backup images (as given by Phase 1) are required for importing, there is no need for a Bidfile, and the Phase 2 will only require the command bpimport with no options.
Phase 2
with Bidfile
/usr/openv/netbackup/bin/admincmd/bpimport -Bidfile
without Bidfile (assuming all backup images listed by Phase 1 are for import)
/usr/openv/netbackup/bin/admincmd/bpimport
Please note that it may be considered easier to import using the Java GUI rather than command line, particularly as Phase 2 requires a Bidfile to be created, or that the import may need to use the -backupid option if importing one backup image at a time is desired.
The bpimport command options may be displayed by the command:
/usr/openv/netbackup/bin/admincmd/bpimport -HELP
