To back up important data, a CPE can upload the current configuration file to the specified server
according to the requirement of an ACS. The device supports uploading only the vendor configuration
file or log file.
NOTE:
The device can download only system software ima
g
es and confi
g
uration files from the ACS, and does no
t
support digital signatures.
CPE status and performance monitoring
An ACS can monitor the parameters of a CPE connected to it. Different CPEs have different performances
and functionalities. Therefore the ACS must be able to identify each type of CPE and monitor each CPE's
current configuration and configuration changes. CWMP also allows the administrator to define monitor
parameters and get the parameter values through an ACS, so as to get the CPE status and statistics
information.
The status and performance that can be monitored by an ACS include:
• Manufacturer name (Manufacturer)
• ManufacturerOUI
• SerialNumber
• HardwareVersion
• SoftwareVersion
• DeviceStatus
• UpTime
• Configuration file (ConfigFile)
• ACS address (URL)
• ACS username (Username)
• ACS password (Password)
• PeriodicInformEnable
• PeriodicInformInterval
• PeriodicInformTime
• CPE address (ConnectionRequestURL)
• CPE username (ConnectionRequestUsername)
• CPE password (ConnectionRequestPassword)
CWMP mechanism
RPC methods
CWMP provides the following major remote procedure call methods for an ACS to manage or monitor
a CPE:
• Get—The ACS gets the value of one or more parameters from the CPE.
• Set—The ACS sets the value of one or more parameters on the CPE.
• Inform—The CPE sends 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.
