Usage guidelines
This command is available in standalone mode.
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, make sure no one reboots or swaps
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
).

Usage guidelines
This command is available in standalone mode.
When the standby MPU starts up, this command disables the system to examine the standby MPU's
startup software images for version inconsistency with the active MPU's current software images. The
standby MPU can start up with a different software version than the active MPU.
