Managing Configuration History and Rollback

After each commit operation, a record of the committed configuration changes is saved. This record
contains only the changes made during the configuration session; it does not contain the complete
configuration. Each record is assigned a unique ID, known as a commitID.
When multiple commitIDs are present, you can use a commitID to identify a previous configuration to
which you want to return, or you can use the commitID to load the configuration changes made during
that configuration session. You can also load configuration changes from multiple commitIDs, and you
can clear commitIDs. If you are thinking about rolling back the configuration to a specific commitID,
consider the following guidelines:
•

configure
telnet ipv4 server max-servers 5
telnet ipv6 server max-servers 5
http server
xml agent corba
commit
You cannot roll back to a configuration that was removed because of package incompatibility.
Configuration rollbacks can succeed only when the configuration passes all compatibility checks
with the currently active Cisco IOS XR software.
If an incompatible configuration is found during the rollback operation, the operation fails and an
error is displayed.
