TABLE 121
Object and OID Access Description
dot1dTpFdbTable
1.3.6.1.2.1.17.4.3
Not
accessible
A table that contains information about unicast entries for which the
bridge has forwarding and filtering information. This information is
used by the transparent bridging function in determining how to
propagate a received frame.
dot1dTpFdbEntry
1.3.6.1.2.1.17.4.3.1
Not
accessible
Information about a specific unicast MAC address for which the bridge
has some forwarding and filtering information.
dot1dTpFdbAddress
1.3.6.1.2.1.17.4.3.1.1
Read only A unicast MAC address for which the bridge has forwarding or filtering
information.
dot1dTpFdbPort
1.3.6.1.2.1.17.4.3.1.2
Read only 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 or filtering information
about this address.
dot1dTpFdbStatus
1.3.6.1.2.1.17.4.3.1.3
Read only The status of this entry.
• other (1) - 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• invalid (2) - this entry is no longer valid (for example, it was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.
dot1dTpPortTable
1.3.6.1.2.1.17.4.4
Not
accessible
A table that contains information about every port that is associated
with this transparent bridge.
dot1dTpPortEntry
1.3.6.1.2.1.17.4.4.1
Not
accessible
A list of information for each port of a transparent bridge.
dot1dTpPort
1.3.6.1.2.1.17.4.4.1.1
Read only The port number of the port for which this entry contains transparent
bridging management information.
dot1dTpPortMaxInfo
1.3.6.1.2.1.17.4.4.1.2
Read only The maximum size of the INFO (non-MAC) field that this port will
receive or transmit.
dot1dTpPortInFrames
1.3.6.1.2.1.17.4.4.1.3
Read only The number of frames that have been received by this port from its
segment.
NOTE: A frame received on the interface corresponding to this port is
only counted by this object if and only if it is for a protocol being
processed by the local bridging function, including the bridge
management frames.
