Usage Guidelines To use this command, you must be in a user group associated with a task group that includes the proper
task IDs.
Use the install rollback command to roll back the configuration to a saved installation point or to the
last committed installation point. Rollback points are created when the router is booted and when
packages are activated, deactivated or committed. When an installation point is created, the
Cisco IOS XR software assigns an ID number to that rollback point. To roll back to a saved installation
point, enter the installation point ID number assigned to it for the point-id argument. When a software
configuration is committed with the
committed installation point. Use the committed keyword to roll back to the last committed installation
point.
Labels can be assigned to installation points using the install label command. Then these labels can be
used to identify a specific installation point that you want to roll back to.
To display the saved rollback points available, use the online help function:
RP/0/RP0/CPU0:router(admin)# install rollback to ?
If a rollback operation is beyond two saved installation points, a router reload is required to avoid system
instability. If a reload is required, a confirmation prompt appears before the reload occurs. Use the install
rollback command with the prompt-level none keywords to automatically ignore any reload
confirmation prompts and proceed with the rollback operation.
If a software operation requires a node reload, the config-register for that node should be set to autoboot.
If the config-register for the node is not set to autoboot, then the system automatically changes the setting
and the node reloads. A message describing the change is displayed.
If a rollback operation requires that a package be activated that is no longer on the system (because the
package had been removed), a message appears in the output of the install rollback command indicating
that the specified installation point is unavailable and that the required package must be added to roll
back the software set to the specified installation point.
Use the test keyword to verify the effects of the proposed operations and determine whether the rollback
operation can be completed. After previewing the effects of the proposed operations, use the
install log
