-- All representations of MAC addresses in this MIB Module use,
-- as a textual convention (i.e. this convention does not affect
-- their encoding), the data type:
MacAddress ::= OCTET STRING (SIZE (6)) -- a 6 octet address in
-- the "canonical" 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
-- 802.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/D9
-- 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).

"Determines how this port behaves when presented

The value 'forced(3)' indicates the port will
always accept and propagate Spanning Tree Explorer
frames. This allows a manually configured
Spanning Tree for this class of packet to be
configured. Note that unlike transparent bridging
this is not catastrophic to the network if there
are loops. The value 'auto-span(1)' can only be
returned by a bridge that both implements the
Spanning Tree Protocol and has use of the protocol
enabled on this port. The behavior of the port for
Spanning Tree Explorer frames is determined by the
state of dot1dStpPortState. If the port is in the
'forwarding' state, the frame will be accepted or
propagated. Otherwise it will be silently
