+ DESCRIPTION
+ "The Bridge MIB module for managing devices that support
+ IEEE 802.1D.
+
+ Copyright (C) The Internet Society (2005). This version of
+ this MIB module is part of RFC 4188; see the RFC itself for
+ full legal notices."
+ REVISION "200509190000Z"
+ DESCRIPTION
+ "Third revision, published as part of RFC 4188.
+
+ The MIB module has been converted to SMIv2 format.
+ Conformance statements have been added and some
+ description and reference clauses have been updated.
+
+ The object dot1dStpPortPathCost32 was added to
+ support IEEE 802.1t and the permissible values of
+ dot1dStpPriority and dot1dStpPortPriority have been
+ clarified for bridges supporting IEEE 802.1t or
+ IEEE 802.1w.
+
+ The interpretation of dot1dStpTimeSinceTopologyChange
+ has been clarified for bridges supporting the Rapid
+ Spanning Tree Protocol (RSTP)."

+BridgeId ::= TEXTUAL-CONVENTION
+ STATUS current
+ DESCRIPTION
+ "The Bridge-Identifier, as used in the Spanning Tree
+ Protocol, to uniquely identify a bridge. Its first two
+ octets (in network byte order) contain a priority value,
+ and its last 6 octets contain the MAC address used to
+ refer to a bridge in a unique fashion (typically, the
+ numerically smallest MAC address of all ports on the
+ bridge)."
+ SYNTAX OCTET STRING (SIZE (8))
+
+Timeout ::= TEXTUAL-CONVENTION
+ DISPLAY-HINT "d"
+ STATUS current
+ DESCRIPTION
+ "A Spanning Tree Protocol (STP) timer in units of 1/100
+ seconds. Several objects in this MIB module represent
+ values of timers used by the Spanning Tree Protocol.
+ In this MIB, these timers have values in units of
+ hundredths of a second (i.e., 1/100 secs).
+
+ These timers, when stored in a Spanning Tree Protocol's
+ BPDU, are in units of 1/256 seconds. Note, however, that
+ 802.1D-1998 specifies a settable granularity of no more
+ than one second for these timers. To avoid ambiguity,
+ a conversion algorithm is defined below for converting
+ between the different units, which ensures a timer's
+ value is not distorted by multiple conversions.
+
+ To convert a Timeout value into a value in units of
+ 1/256 seconds, the following algorithm should be used:
+
+ b = floor( (n * 256) / 100)
+
+ where:
+ floor = quotient [ignore remainder]
+ n is the value in 1/100 second units
+ b is the value in 1/256 second units
+
+ To convert the value from 1/256 second units back to
+ 1/100 seconds, the following algorithm should be used:
+
+ n = ceiling( (b * 100) / 256)
+
+ where:
+ ceiling = quotient [if remainder is 0], or
+ quotient + 1 [if remainder is nonzero]
+ n is the value in 1/100 second units
+
+ b is the value in 1/256 second units
+
+ Note: it is important that the arithmetic operations are
+ done in the order specified (i.e., multiply first,
+ divide second)."
