This object is used to enable customer spanning-tree Debug Statements in the STP Module. A FOUR BYTE integer is used for enabling the level of debugging. Each BIT in the four byte integer, represents a particular level of Debug. The mapping between the bit positions & the level of debug is as follows: 0 - Init and Shutdown Debug statements 1 - Management Debug statements 2 - Memory related Debug statements 3 - BPDU related Debug statements 4 - Event Handling Debug statements 5 - Timer Module Debug statements 6 - Port Information SEM Debug statements 7 - Port Receive SEM Debug statements 8 - Role Selection SEM Debug statements 9 - Role Transition SEM Debug statements 10 - State Transition SEM Debug statements 11 - Protocol Migration SEM Debug statements 12 - Topology Change SEM Debug statements 13 - Port Transmit SEM Debug statements 14 - Bridge Detection SEM Debug statements 15 - All Failure Debug statements 16 - Redundancy code flow Debug statements 17 - State Machine variable changes Debug statements 18 - Port Receive Pseudo Information SEM Debug statements The remaining bits are unused. Combination of debug levels are also allowed. For example if the bits 0 and 1 are set, then the Debug statements related to Init-Shutdown and management will be printed. The user has to enter the corresponding INTEGER VALUE for the bits set. For example if bits 0 and 1 are to be set then user has to give the value for this object as 3.
