Deleting Commit Ids; Configuring Logging And Logging Correlation - Cisco ASR 9000 Getting Started Manual

Configuring Logging and Logging Correlation

To load rollback configuration changes from the current configuration to a specific session, go to global
configuration or administration configuration mode and enter the load rollback changes to commit ID
command:
RP/0/RSP0/CPU0:router(config)# load rollback changes to 1000000068
Building configuration...
Loading.
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, go to global configuration or administration configuration mode and enter the load rollback
changes last commit-range command:
RP/0/RSP0/CPU0:router(config)# load rollback changes last 6
Building configuration...
Loading.
221 bytes parsed in 1 sec (220)bytes/sec
In the preceding example, the command loads the rollback configuration changes for the last six commit
IDs.
To load the rollback configuration for a specific commit ID, go to global configuration or administration
configuration mode and enter the load rollback changes commit ID command:
RP/0/RSP0/CPU0:router(config)# load rollback changes 1000000060
Building configuration...
Loading.
199 bytes parsed in 1 sec (198)bytes/sec

Deleting Commit IDs

You can delete the oldest configuration commit IDs by entering the clear configuration commits
command in EXEC or administration EXEC mode. The clear configuration commits command must
be followed by either the amount of disk space to reclaim or number of commit IDs to delete. To reclaim
disk space from the oldest commit IDs, enter the clear configuration commits command followed by
the diskspace keyword and number of kilobytes to reclaim:
RP/0/RSP0/CPU0:router# clear configuration commits 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 commit IDs, enter the clear configuration commits command
followed by the oldest keyword and number of commit IDs to delete:
RP/0/RSP0/CPU0:router# clear configuration commits oldest 5
Deleting 5 rollback points '1000000005' to '1000000009'
80 KB of disk space will be freed. Continue with deletion?[confirm]

Configuring Logging and Logging Correlation

System messages generated by the Cisco IOS XR software can be logged to a variety of locations based
on the severity level of the messages. For example, you could direct information messages to the system
console and also log debugging messages to a network server.
