This object is used to enable Debug Statements in the RSTP
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
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.
