Configuration parameter deployment
When a CPE logs in to an ACS, the ACS can automatically apply some configurations to the CPE for it to
perform auto configuration.

RPC methods
In the CWMP, a series of RPC methods are used for intercommunication between a CPE and an ACS. The
primary RPC methods are described as follows:
•
Get—Method used by an ACS to get the value of one or more parameters of a CPE.
•
Set— Method used by an ACS to set the value of one or more parameters of a CPE.
•
Inform— Method used by a CPE to send an Inform message to an ACS whenever the CPE initiates a
connection to the ACS, or the CPE's underlying configuration changes, or the CPE periodically sends
its local information to the ACS.
Download— Method used by an ACS to require a CPE to download a specified file from the
•
specified URL, ensuring upgrading of CPE software and auto download of the vendor configuration
file.
•
Upload— Method used by an ACS to require a CPE to upload a specified file to the specified
location.
Reboot— Method used by an ACS to reboot a CPE remotely when the CPE encounters a failure or
•
software upgrade is needed.
Table 4
lists the auto-configuration parameters supported by the switch.
Function
Updates the local configuration file on the CPE. The ACS delivers a
configuration file to the CPE in one of the following formats: file or
current configuration.
Updates the ACS address kept on the CPE. The parameter is used
when there is an active and standby ACS switchover.
Automatically synchronizes the username and password on the CPE
when those on the ACS change. The parameters are also used to
inform the CPE of the authentication information of the standby ACS
server when there is an active and standby ACS switchover.
Enables the sending of Inform messages.
Configures the CPE to send an Inform message periodically. The
parameter is used for querying updates and information backup
regularly.
Configures the CPE to send an Inform message at a specified time. The
parameter is used for querying updates and information backup at a
specified time.
Configures the CPE username and password for connection to the
ACS.
