Automatic Synchronization
Use the CLI syntax displayed below to configure synchronization components relating to active-
to-standby CPM switchover. In redundant systems, synchronization ensures that the active and
standby CPMs have identical operational parameters, including the active configuration, CPM,
and XCM images in the event of a failure or reset of the active CPM.
The force-switchover command forces a switchover to the standby CPMTo 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).
Note: 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
