Chapter 14 CWMP Device Operations
Connection Modes for Device Operations
All device operations are executed before other configuration services, such as data synchronization,
configuration synchronization, and firmware rules download.
Caution You should not perform device configuration updates using device operations. The configuration process
can overwrite any settings that you configured by using device operations.
Connection Modes for Device Operations
Cisco BAC enables the performing of device operations in three modes:
• Immediate
• On-connect
• Asynchronous
Immediate Mode
An immediate execution assumes that the device is reachable and is performed by the DPE first issuing
a connection request to the device. If the device is not reachable, the operations automatically fail. You
can run multiple operations in the same batch to improve performance, creating a single connection
request and, thus, a single management session with the CWMP device.
A client uses a timeout period to post the API batch in immediate mode. If no timeout is set, the duration
for immediate operations to time out is, by default, 60 seconds. If a device operation times out or its
batch times out, an error is returned.
