Overview

PandM is a CCSP component that implements core provisioning and management functionality of the device.  Its primary role is to respond to commands from other CCSP components and protocol agents that need to set or query variables pertaining to  provisioning and management. Its interface to other components uses the CCSP Message Bus interface and is based around a data model derived from  TR-181 (TR-157, TR-143) along with CCSP specific extensions. PandM is a Key module which holds parameters related to many key services like: dhcpv6, LAN, DeviceInfo etc. It maintains a TR181 data model XML file with dbus object path as /com/cisco/spvtg/ccsp/pam . Has a layered architecture which makes it less complex for GET/SET implementation.
