Usage Guidelines
By default, the system synchronizes all system files, which is the typical setting for most applications.
However, you might want to not synchronize certain files for specialized applications.
For example, if you have configured the active and standby PRE1 modules to run different versions of
Cisco IOS software, you might want to use different configuration files as well. In this case, you would
not synchronize the startup configuration file.
Examples
The following example shows the system being configured to synchronize only the startup configuration
file:
router(config)# redundancy
