16: -- All representations of MAC addresses in this MIB Module use,

20: MacAddress ::= OCTET STRING (SIZE (6)) -- a 6 octet address in
21: -- the "canonical" order
22: -- defined by IEEE 802.1a, i.e., as if it were transmitted least
23: -- significant bit first, even though 802.5 (in contrast to other
24: -- 802.x protocols) requires MAC addresses to be transmitted most
25: -- significant bit first.
26: --
27: -- 16-bit addresses, if needed, are represented by setting their
28: -- upper 4 octets to all 0's, i.e., AAFF would be represented
29: -- as 00000000AAFF.

32: -- Similarly, all representations of Bridge-Id in this MIB Module
33: -- use, as a textual convention (i.e. this convention does not affect
34: -- their encoding), the data type:
35: BridgeId ::= OCTET STRING (SIZE (8)) -- the Bridge-Identifier as
36: -- used in the Spanning Tree
37: -- Protocol to uniquely identify a bridge. Its first two octets
38: -- (in network byte order) contain a priority value and its last

40: -- unique fashion (typically, the numerically smallest MAC address
41: -- of all ports on the bridge).
42: -- Several objects in this MIB module represent values of timers
43: -- used by the Spanning Tree Protocol. In this MIB, these timers
44: -- have values in units of hundreths of a second (i.e. 1/100 secs).
45: -- These timers, when stored in a Spanning Tree Protocol's BPDU,
46: -- are in units of 1/256 seconds. Note, however, that 802.1d/D9
47: -- specifies a settable granularity of no more than 1 second for
48: -- these timers. To avoid ambiguity, a data type is defined here
49: -- as a textual convention and all representation of these timers
50: -- in this MIB module are defined using this data type. An algorithm
51: -- is also defined for converting between the different units, to
52: -- ensure a timer's value is not distorted by multiple conversions.
53: -- The data type is:
54:
55: Timeout ::= INTEGER -- a STP timer in units of 1/100 seconds
55: warning -
warning: type `Timeout' has no format specification
56:
57: -- To convert a Timeout value into a value in units of
58: -- 1/256 seconds, the following algorithm should be used:
59: --
60: -- b = floor( (n * 256) / 100)

63: -- floor = quotient [ignore remainder]
64: -- n is the value in 1/100 second units

67: -- To convert the value from 1/256 second units back to
68: -- 1/100 seconds, the following algorithm should be used:
69: --
70: -- n = ceiling( (b * 100) / 256)
71: --
72: -- where:
73: -- ceiling = quotient [if remainder is 0], or

75: -- n is the value in 1/100 second units
76: -- b is the value in 1/256 second units
