Enabling software synchronization from the active
MPU to the standby MPU at startup
This feature is available only when the device is operating in standalone mode. To synchronize software
from the global active MPU to other MPUs on an IRF fabric, use the irf auto-update enable command. For
more information about software auto-update, see IRF Configuration Guide.
When the standby MPU starts up, this feature examines its startup software images for version
inconsistency with the current software images on the active MPU. If the software versions are different,
the standby MPU copies the current software images of the active MPU, specifies them as startup
software images, and reboots with these images.
IMPORTANT:
To ensure a successful synchronization in a multi-user environment, prevent users from rebooting or
swapping 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
).
