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
