RFC 1493 Bridge MIB July 1993
STATUS mandatory
DESCRIPTION
"Information about a specific unicast MAC address
for which the bridge has some forwarding and/or
filtering information."
INDEX { dot1dTpFdbAddress }
::= { dot1dTpFdbTable 1 }
Dot1dTpFdbEntry ::=
SEQUENCE {
dot1dTpFdbAddress
MacAddress,
dot1dTpFdbPort
INTEGER,
dot1dTpFdbStatus
INTEGER
}
dot1dTpFdbAddress OBJECT-TYPE
SYNTAX MacAddress
ACCESS read-only
STATUS mandatory
DESCRIPTION
"A unicast MAC address for which the bridge has
forwarding and/or filtering information."
REFERENCE
"IEEE 802.1D-1990: Section 3.9.1, 3.9.2"
::= { dot1dTpFdbEntry 1 }
dot1dTpFdbPort OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-only
STATUS mandatory
DESCRIPTION
"Either the value '0', or the port number of the
port on which a frame having a source address
equal to the value of the corresponding instance
of dot1dTpFdbAddress has been seen. A value of
'0' indicates that the port number has not been
learned but that the bridge does have some
forwarding/filtering information about this
address (e.g. in the dot1dStaticTable).
Implementors are encouraged to assign the port
value to this object whenever it is learned even
for addresses for which the corresponding value of
dot1dTpFdbStatus is not learned(3)."

dot1dTpFdbStatus OBJECT-TYPE
SYNTAX INTEGER {
other(1),
invalid(2),
learned(3),
self(4),
mgmt(5)
}
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The status of this entry. The meanings of the
values are:
other(1) : none of the following. This would
include the case where some other
MIB object (not the corresponding
instance of dot1dTpFdbPort, nor an
entry in the dot1dStaticTable) is
being used to determine if and how
frames addressed to the value of
the corresponding instance of
dot1dTpFdbAddress are being
forwarded.
invalid(2) : this entry is not 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."

"A table containing filtering information

forwarded. The value of zero in this table as the
port number from which frames with a specific
destination address are received, is used to
specify all ports for which there is no specific
entry in this table for that particular
destination address. Entries are valid for
unicast and for group/broadcast addresses."
