Administrative Tasks
286 Basic System Configuration Guide
To enable automatic synchronization, either the boot-env parameter or the config parameter 
must be specified. The synchronization occurs when the admin save or bof save commands 
are executed.
When the boot-env parameter of the synchronize command is specified, the bof.cfg, 
primary/secondary/tertiary configuration files (.cfg and .ndx), li, and ssh files are 
automatically synchronized. When the config parameter is specified, only the configuration 
files are automatically synchronized.
Synchronization also occurs whenever the BOF is modified and when an admin>save 
command is entered with no filename specified.
Boot-Env Option
The boot-env option enables a synchronization of all the files used in system initialization.
When configuring the system to perform this synchronization, the following occurs:
1. The BOF used during system initialization is copied to the same compact flash on the 
standby CPM (in redundant systems). The synchronization parameters on the 
standby CPM are preserved. 
2. The primary, secondary, and tertiary images, (provided they are locally stored on the 
active CPM) are copied to the same compact flash on the standby CPM. 
3. The primary, secondary, and tertiary configuration files, (provided they are locally 
stored on the active CPM) are copied to the same compact flash on the standby CPM. 
Config Option
The config option synchronizes configuration files by copying the files specified in the active 
CPM BOF file to the same compact flash on the standby CPM.
Both image files (CPM and IOM) on the 7450 ESS must be located in the same directory. 
Failure to locate and synchronize both images causes an error to be generated.
