Incremental (Partial) Configuration
After the network is running, new services can be added by using the Cisco IOS CNS agent. Incremental
(partial) configurations can be sent to the switch. The actual configuration can be sent as an event payload by
way of the event gateway (push operation) or as a signal event that triggers the switch to initiate a pull operation.
(partial) configurations can be sent to the switch. The actual configuration can be sent as an event payload by
way of the event gateway (push operation) or as a signal event that triggers the switch to initiate a pull operation.
The switch can check the syntax of the configuration before applying it. If the syntax is correct, the switch
applies the incremental configuration and publishes an event that signals success to the configuration server.
If the switch does not apply the incremental configuration, it publishes an event showing an error status. When
the switch has applied the incremental configuration, it can write it to nonvolatile random-access memory
(NVRAM) or wait until signaled to do so.

Synchronized Configuration
When the switch receives a configuration, it can defer application of the configuration upon receipt of a
write-signal event. The write-signal event tells the switch not to save the updated configuration into its
NVRAM. The switch uses the updated configuration as its running configuration. This ensures that the switch
configuration is synchronized with other network activities before saving the configuration in NVRAM for
use at the next reboot.

Automated CNS Configuration
To enable automated CNS configuration of the switch, you must first complete the prerequisites listed in this
topic. When you complete them, power on the switch. At the setup prompt, do nothing; the switch begins the
initial configuration. When the full configuration file is loaded on your switch, you do not need to do anything
else.

For more information on what happens during initial configuration, see "Related Topics."
