RFC 2674
DESCRIPTION
"A unicast MAC address for which the device has
forwarding and/or filtering information."
::= { dot1qTpFdbEntry 1 }
dot1qTpFdbPort OBJECT-TYPE
SYNTAX INTEGER (0..65535)
MAX-ACCESS read-only
STATUS current
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 dot1qTpFdbAddress has
been seen. A value of '0' indicates that the port
number has not been learned but that the device does
have some forwarding/filtering information about this
address (e.g. in the dot1qStaticUnicastTable).
Implementors are encouraged to assign the port value to
this object whenever it is learned even for addresses
for which the corresponding value of dot1qTpFdbStatus is
not learned(3)."

dot1qTpFdbStatus OBJECT-TYPE
SYNTAX INTEGER {
other(1),
invalid(2),
learned(3),
self(4),
mgmt(5)

MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The status of this entry. The meanings of the values
are:
other(1) - none of the following. This may include
the case where some other MIB object (not the
corresponding instance of dot1qTpFdbPort, nor an
entry in the dot1qStaticUnicastTable) is being
used to determine if and how frames addressed to
the value of the corresponding instance of
dot1qTpFdbAddress 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invalid(2) - this entry is no longer valid (e.g., it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 dot1qTpFdbPort was learned and is being used.
Bell, et al. Standards Track [Page 46]
RFC 2674 Bridge MIB Extensions August 1999
self(4) - the value of the corresponding instance of
dot1qTpFdbAddress represents one of the device's
addresses. The corresponding instance of
dot1qTpFdbPort indicates which of the device's
ports has this address.
mgmt(5) - the value of the corresponding instance of
dot1qTpFdbAddress is also the value of an
existing instance of dot1qStaticAddress."

A row creation operation in this table for an entry with a local
VlanIndex value may fail if the current value of this object
is not used as the index. Even if the value read is used,
there is no guarantee that it will still be the valid index
when the create operation is attempted - another manager may
have already got in during the intervening time interval.
In this case, dot1qNextFreeLocalVlanIndex should be re-read
and the creation re-tried with the new value.
This value will automatically change when the current value is
used to create a new row."

for these objects. This mechanism is provided as a way to read
64-bit counters for agents which support only SNMPv1.
Note that the reporting of most-significant and least-
significant counter bits separately runs the risk of missing
an overflow of the lower bits in the interval between sampling.
The manager must be aware of this possibility, even within the
same varbindlist, when interpreting the results of a request or

6. Acknowledgments
This document expands upon previous work which resulted in the
original bridge MIB [BRIDGEMIB].
Much of the groundwork for this document was performed by the IEEE
802.1 working group during the definition of the IEEE 802.1D updates
[802.1D] and IEEE 802.1Q [802.1Q].
The authors wish to thank the members of the Bridge Working Group and
David Harrington in particular for their many comments and
suggestions which improved this effort.
7. Security Considerations
There are a number of management objects defined in this MIB that
have a MAX-ACCESS clause of read-write and/or read-create. Such
objects may be considered sensitive or vulnerable in some network
environments. The support for SET operations in a non-secure
environment without proper protection can have a negative effect on
network operations.
SNMPv1 by itself is not a secure environment. Even if the network
itself is secure (for example by using IPSec), even then, there is no
control as to who on the secure network is allowed to access and
GET/SET (read/change/create/delete) the objects in this MIB.
It is recommended that the implementers consider the security
features as provided by the SNMPv3 framework. Specifically, the use
of the User-based Security Model [USM] and the View-based Access
Control Model [VACM] is recommended.
Bell, et al. Standards Track [Page 80]
RFC 2674 Bridge MIB Extensions August 1999
It is then a customer/user responsibility to ensure that the SNMP
entity giving access to an instance of this MIB, is properly
configured to give access to the objects only to those principals
(users) that have legitimate rights to indeed GET or SET
(change/create/delete) them.
