Chapter 4 Commands for the Cisco uBR10012 Router
auto-sync
auto-sync
To configure what system files the active and standby Performance Routing Engine (PRE1) modules
automatically synchronize, use the
auto-sync command in redundancy configuration (main-cpu) mode.
To disable the synchronization of all or some files, use the no form of this command.
auto-sync { bootvar | config-register | standard | running-config | startup-config }
no auto-sync { bootvar | config-register | standard | running-config | startup-config }
Syntax Description
Defaults The system defaults to synchronizing all system files ( auto-sync standard ).
Command Modes Redundancy configuration, main-cpu mode
Command History
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
bootvar Specifies that the PRE1 modules should synchronize the following boot
variables:
•
BOOT—Set by the boot system device:filename command
•
CONFIG_FILE—Set by the boot config device:filename command
•
BOOTLDR—Set by the boot bootldr device:filename command
config-register Specifies that the PRE1 modules should synchronize the configuration
register values.
standard Specifies that the PRE1 modules should synchronize all of the system files
(default).
running-config Specifies that the PRE1 modules should synchronize the run-time
configuration files.
startup-config Specifies that the PRE1 modules should synchronize the startup
configuration files.
