To make sure the standby MPU always runs the same software images as the active MPU, configure both
the version auto-update enable command and the undo version check ignore command.
The startup software version check function examines the standby MPU's startup software images for
version inconsistency with the active MPU's current software images at startup. If their software versions
are different, the standby MPU copies the current software images of the active MPU, specifies them as
main startup software images, and reboots with these images.
To ensure a successful synchronization in a multi-user environment, do not reboot or swap MPUs during
the software synchronization process. You can configure the information center to output the
synchronization status to configuration terminals (see Network Management and Monitoring
Configuration Guide).
