File synchronization
6
•
Running-config file – The running-config file resides in system memory.
You can perform the following tasks related to file synchronization:
-
Compare files on the active module with files on the standby module and immediately
synchronize any files that are different.
-
Immediately synchronize all files between the active and standby modules.
The following sections explain how to perform these tasks.
Comparing and synchronizing files
You can initiate a comparison of the flash memory, system-config file, and running-config file on the
active management module with the files on the standby module, and synchronize the files
immediately if differences exist. When you synchronize the files, the active module replaces files on
the standby module.
To compare and synchronize files between active and standby modules, enter the sync-standby
command at the Privileged EXEC level of the CLI.
Syntax: sync-standby
Synchronizing files without comparison
You can synchronize the flash memory, system-config file, and running-config file immediately
without comparison. When you synchronize the files, the active module replaces the files on the
standby module.
To immediately synchronize the files between the active and standby modules, enter the
force-sync-standby command at the Privileged EXEC level of the CLI.
Syntax: force-sync-standby
File synchronization between management
and interface modules
An interface module can have two IronWare images: primary and secondary. These images contain
layer 1 – 3 software, and reside in flash memory. Either the primary or secondary image is run by
the interface module from this location.
If you copy the primary or secondary image to all interface modules using the copy all command,
the management module makes a copy of the file and stores it in flash memory under the names
lp-primary-0 or lp-secondary-0 . The images are stored in the flash memory only and are not run by
the management module or the interface modules. If you copy the primary or secondary IronWare
image to a specified device slot using the copy command with the
<slot-number> variable, the
management module does not make a copy of the file.
If the management module has a copy of the primary or secondary image in flash memory, by
default, the router synchronizes, or prompts you to synchronize, interface module images between
the management module and the interface modules during the boot process. When the router
synchronizes the images, the image is copied from management module flash memory to the
interface module flash memory (the interface module default boot source).
