Configuring Rollback
before proceeding with the operation. In a supervisor switchover, the checkpoint is completed on the new
active unit.
If a process restart or supervisor switchover occurs during a rollback operation, after the restart or switchover
completes, the rollback will resume from its previous state and complete successfully.

Virtualization Support

Cisco NX-OS creates a checkpoint of the running configuration in the virtual device context (VDC) that you
are logged into. You can create different checkpoint copies in each VDC. You cannot apply the checkpoint
of one VDC into another VDC. By default, Cisco NX-OS places you in the default VDC. See the Cisco Nexus
7000 Series NX-OS Virtual Device Context Configuration Guide.
VDC configuration does not support checkpoints for any operations, including (but not limited to) VDC
creation, VDC deletion, VDC suspension, VDC reloading, VDC renaming, VDC interface allocation, shared
interface allocation, FCoE VLAN allocation, resource allocation, and resource templates. You should create
your checkpoint from within a specific VDC.
