-- All representations of MAC addresses in this MIB Module

MacAddress ::= OCTET STRING (SIZE (6))    -- a 6 octet address

                                          -- order
-- defined by IEEE 802.1a, i.e., as if it were transmitted
-- least significant bit first, even though 802.5 (in
-- contrast to other n802.x protocols) requires MAC
-- addresses to be transmitted most significant bit first.
--
-- 16-bit addresses, if needed, are represented by setting
-- their upper 4 octets to all 0's, i.e., AAFF would be
-- represented as 00000000AAFF.


-- Similarly, all representations of Bridge-Id in this MIB
-- Module use, as a textual convention (i.e. this
-- convention does not affect their encoding), the data
-- type:

BridgeId ::= OCTET STRING (SIZE (8))   -- 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).

-- 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 hundreths 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-1990 specifies a settable granularity of
-- no more than 1 second for these timers.  To avoid
-- ambiguity, a data type is defined here as a textual
-- convention and all representation of these timers
-- in this MIB module are defined using this data type.  An
-- algorithm is also defined for converting between the
-- different units, to ensure a timer's value is not
-- distorted by multiple conversions.
-- The data type is:

Timeout ::= INTEGER -- a STP timer in units of 1/100 seconds

-- 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 non-zero]
--      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).
