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)."

of the corresponding instance of dot1dTpFdbAddress has

number has not been learned, but that the bridge does
have some forwarding/filtering information about this

and how frames addressed to the value of the
corresponding instance of dot1dTpFdbAddress are
being forwarded.
invalid(2) - this entry is no longer valid (e.g.,
it was learned but has since aged out), but has
not yet been flushed from the table.
learned(3) - the value of the corresponding instance
of dot1dTpFdbPort was learned, and is being
used.
self(4) - the value of the corresponding instance of
dot1dTpFdbAddress represents one of the bridge's
addresses. The corresponding instance of
dot1dTpFdbPort indicates which of the bridge's
ports has this address.
mgmt(5) - the value of the corresponding instance of
dot1dTpFdbAddress is also the value of an
existing instance of dot1dStaticAddress."

MAX-ACCESS read-create

DESCRIPTION
"The set of ports to which frames received from a
specific port and destined for a specific MAC address,
are allowed to be forwarded. Each octet within the
value of this object specifies a set of eight ports,
with the first octet specifying ports 1 through 8, the
second octet specifying ports 9 through 16, etc. Within
each octet, the most significant bit represents the
lowest numbered port, and the least significant bit
represents the highest numbered port. Thus, each port
of the bridge is represented by a single bit within the
value of this object. If that bit has a value of '1',
then that port is included in the set of ports; the port
is not included if its bit has a value of '0'. (Note
that the setting of the bit corresponding to the port
from which a frame is received is irrelevant.) The
default value of this object is a string of ones of
appropriate length.
The value of this object may exceed the required minimum
maximum message size of some SNMP transport (484 bytes,
in the case of SNMP over UDP, see RFC 3417, section 3.2).
SNMP engines on bridges supporting a large number of
ports must support appropriate maximum message sizes."
