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 does the following:
1. Copies the current software images of the active MPU.
2. Specifies the images as startup software images.
3. Reboots with these images.
IMPORTANT:
To ensure a successful synchronization in a multiuser environment, prevent users from rebootin
