Previewing Rollback Configuration Changes
The show configuration rollback changes command allows you to preview the configuration changes
that take place if you roll back the configuration to a specific commitID. For example, if you want to roll
back the configuration to a specific point, all configuration changes made after that point must be
undone. This rollback process is often accomplished by executing the "no" version of commands that
must be undone.
To display the prospective rollback configuration changes from the current configuration to a specific
commitID, go to EXEC or administration EXEC mode and enter the show configuration rollback
changes to commitId command. In the following example, the command help displays the available
commitIDs, and then the rollback changes are displayed.
RP/0/RP1/CPU0:router# show configuration rollback changes to ?
1000000217
1000000218
1000000219
RP/0/RP1/CPU0:router# show configuration rollback changes to 1000000218
Building configuration...
no interface Loopback100
interface POS0/1/0/0

no route-policy xx
end
To display the prospective rollback configuration changes from the current configuration to a specified
number of previous sessions, go to EXEC or administration EXEC mode and enter the show
configuration rollback changes last commit-range command:
RP/0/RP0/CPU0:router# show configuration rollback changes last 2
Building configuration...
interface Loopback3

no ipv4 address 10.0.1.1 255.0.0.0
exit
interface Loopback4
no description
no ipv4 address 10.0.0.1 255.0.0.0
end
In the preceding example, the command display shows the proposed rollback configuration changes for
the last two commit IDs.
