This object is used to enable trace statements in DNS Resolver Module. A four byte integer is used for enabling the trace level. Each bit in the four byte integer represents a particular trace level. The mapping between the bit positions & the trace level is as follows: Bit 1 - Init and Shutdown traces Bit 2 - Management traces Bit 3 - Data Path traces Bit 4 - Control Plane traces Bit 5 - Packet Dump traces Bit 6 - Traces related to all resources except buffers Bit 7 - All Failure traces Bit 8 - Buffer allocation/release traces The remaining bits are unused. Combination of levels are also allowed. For example if the bits 1 and 2 are set, then the trace statement related to Management and Data Path related messages will be printed. The user has to enter the corresponding integer value for the bits set. For example if bits 1 and 2 are to be set ,then user has to give the value 0x0003.
