65    DESCRIPTION
66         "Third revision, published as part of RFC 4188.
67
68         The MIB module has been converted to SMIv2 format.
69         Conformance statements have been added and some
70         description and reference clauses have been updated.
71
72         The object dot1dStpPortPathCost32 was added to
73         support IEEE 802.1t and the permissible values of
74         dot1dStpPriority and dot1dStpPortPriority have been
75         clarified for bridges supporting IEEE 802.1t or
76         IEEE 802.1w.
77
78         The interpretation of dot1dStpTimeSinceTopologyChange
79         has been clarified for bridges supporting the Rapid
80         Spanning Tree Protocol (RSTP)."

99        octets (in network byte order) contain a priority value,

103        bridge)."

108    STATUS      current
109    DESCRIPTION
110        "A Spanning Tree Protocol (STP) timer in units of 1/100
111        seconds.  Several objects in this MIB module represent
112        values of timers used by the Spanning Tree Protocol.
113        In this MIB, these timers have values in units of
114        hundredths of a second (i.e., 1/100 secs).
115
116        These timers, when stored in a Spanning Tree Protocol's
117        BPDU, are in units of 1/256 seconds.  Note, however, that
118        802.1D-1998 specifies a settable granularity of no more
119        than one second for these timers.  To avoid ambiguity,
120        a conversion algorithm is defined below for converting
121        between the different units, which ensures a timer's
122        value is not distorted by multiple conversions.
123
124        To convert a Timeout value into a value in units of
125        1/256 seconds, the following algorithm should be used:
126
127            b = floor( (n * 256) / 100)
128
129        where:
130            floor   =  quotient [ignore remainder]
131            n is the value in 1/100 second units
132            b is the value in 1/256 second units
133
134        To convert the value from 1/256 second units back to
135        1/100 seconds, the following algorithm should be used:
136
137            n = ceiling( (b * 100) / 256)
138
139        where:
140            ceiling = quotient [if remainder is 0], or
141                      quotient + 1 [if remainder is nonzero]
142            n is the value in 1/100 second units
143            b is the value in 1/256 second units
144
145        Note: it is important that the arithmetic operations are
146        done in the order specified (i.e., multiply first,
147        divide second)."
