CPU Switch Module Redundancy Commands
CPU switch module redundancy provides protection against CPU switch module failure. Use the
following commands to configure and monitor CPU switch module redundancy operatio ns.
auto-sync running-config
To selectively enable only automatic synchronizing of the running configuration on the active processor
to the standby CPU switch module, use the auto-syncrunning-config comman d. To disable automatic
synchronizing of the running configuration, use the no form of this co mman d.
auto-sync running-config
no auto-sync running-config
Syntax Description This command has no other arguments or keywords.
Defaults Enabled
Command Modes Redundancy configuration
Command History
Usage Guidelines Use this command to enable or disable automatic synchronizing of the running configuration without
affecting the following types of synchronization:
•Startup configuration
•Dynamic database synchronizing
When a CPU switch module switchover occurs, the standby CPU switch module normally uses the
running configuration rather than the startup configuration. However, if auto-sync running-config is
disabled when a CPU switch module switchover occurs, the stan dby CPU s witch module uses the st artup
configuration.
In maintenance mode, all database synchronizing to the standby CPU switch module is disabled even if
auto-sync running-config is enabled.
Examples The following example shows how to disable automatic synchronizing of the running configuration.
Switch# configure terminal
Switch(config)# redundancy
Switch(config-red)# no auto-sync running-config
