Description: This object is used to enable Debug Statements in the MSTP 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 (valid in the case of MSTP alone) 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

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.

Setting the Debug Option to any value will cause the Trace Option to be set to 0 (i.e.) the Trace Option and Debug Option are mutually exclusive.
