Saving and Loading Target Configuration Files

To load rollback configuration changes from the current configuration to a specific session, enter the

load rollback changes to commitId command:

RP/0/0/CPU0:router(config)# load rollback changes to 1000000068

Building configuration...

233 bytes parsed in 1 sec (231)bytes/sec

To load rollback configuration changes from the current configuration to a specified number of previous

sessions, enter the load rollback changes last commit-range command:

RP/0/0/CPU0:router(config)# load rollback changes last 6

Building configuration...

221 bytes parsed in 1 sec (220)bytes/sec

In the preceding example, the command loads the rollback configuration changes for the last six

commitIDs.

To load the rollback configuration for a specific commitID, enter the load rollback changes commitId

command:

RP/0/0/CPU0:router(config)# load rollback changes 1000000060

Building configuration...

199 bytes parsed in 1 sec (198)bytes/sec

You can delete the oldest configuration commitIDs by entering the clear configuration commit

command in EXEC mode. The clear configuration commit command must be followed by either the

amount of disk space you want to reclaim or number of commitIDs you want to delete. To reclaim disk

space from the oldest commitIDs, enter the clear configuration commit command followed by the

keyword diskspace and number of kilobytes to reclaim:

RP/0/0/CPU0:router# clear configuration commit diskspace 50

Deleting 4 rollback points '1000000001' to '1000000004'

64 KB of disk space will be freed. Continue with deletion?[confirm]

To delete a specific number of the oldest commitIDs, enter the clear configuration commit command

followed by the keyword oldest and number of commitIDs to delete:

RP/0/0/CPU0:router# clear configuration commit oldest 5

Deleting 5 rollback points '1000000005' to '1000000009'

80 KB of disk space will be freed. Continue with deletion?[confirm]

Saving and Loading Target Configuration Files

Target configurations can be saved to a separate file without committing them to the running

configuration. Target configuration files can then be loaded at a later time and further modified or

committed. The following sections describe how to save and load target configurations:
