Managing Configuration History and Rollback
The Cisco IOS XR software automatically saves up to 100 of the most recent commitIDs. The following
sections describe how to manage configuration changes and roll back to a previously committed
configuration:
•Displaying the CommitIDs, page 5-4
•Displaying the Configuration Changes Recorded in a CommitID, page 5-4
•Previewing Rollback Configuration Changes, page 5-5
•Rolling Back the Configuration to a Specific Rollback Point, page 5-6
•Rolling Back the Configuration over a Specified Number of Commits, page 5-6
•Loading CommitID Configuration Changes to the Target Configuration, page 5-7
•Loading Rollback Configuration Changes to the Target Configuration, page 5-8
•Deleting CommitIDs, page 5-8
Displaying the CommitIDs
To display a history of up to 100 of the most recent commitIDs, enter the show configuration commit
list command in EXEC or administration EXEC mode. Up to 100 of the most recent commitIDs are
saved by the system. Each commitID entry shows the user who committed configuration changes, the
connection used to execute the commit, and commitID time stamp.
The commitIDs are shown in the “Label/ID” column. The following example shows the
show configuration commit list command display in EXEC and administration EXEC modes:
RP/0/RP1/CPU0:router# show configuration commit list
SNo. Label/ID User Line Client Time Stamp

Displaying the Configuration Changes Recorded in a CommitID
To display the configuration changes made during a specific commit session (commitID), go to EXEC
or administration EXEC mode and enter the show configuration commit changes command followed
by a commitID number. The easiest way to determine the commitID is to enter the show configuration
commit changes ? command first. In the following example, the command help is used to display the
available commitIDs, and then the changes for a specific commitID are displayed:
RP/0/RP1/CPU0:router(admin)# show configuration commit changes ?
last Changes made in the most recent <n> commits
since Changes made since (and including) a specific commit
2000000020 Commit ID
