--VERSION 3.0
|
|
-- History :
|
|
-- * 06-26-97 Supports versions:
|
|
-- 2.3 to 2.4 (s13)
|
|
-- 2.3 to 2.4 (s16)
|
|
-- 1.1 to 1.2 (s6)
|
|
--
|
|
-- * [07-01-97:Nutan] Changed the version number from 1.2 to 3.0.
|
|
--
|
|
-- This mib is basically the same as the standard Bridge MIB
|
|
-- (RFC 1493), except that all variables now have an additional
|
|
-- index, namely LAN Id. This allows the represenation of
|
|
-- multiple bridges for multiples LANs within the same box.
|
|
-- The object descriptors have been kept similar to the original
|
|
-- ones, except "dot1d" has been changed to "atbr"

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).

significant bit represents the lowest numbered
