Possible values are:


bridging, noBridging
                

This object determines whether bridging is performed
by this system.  If this is set to noBridging (2),
all functions associated with bridging are disabled,
including Spanning Tree, Learning, and Source Routing.    

This table is an extension of the dot1dStaticTable
from the Bridge MIB, rfc1286.  One additional
column has been defined to identify the proper wide
area address when bridging over a wide area port.    

An extension to the dot1dStaticTable from rfc1286.    

A unicast MAC address for which the bridge has
forwarding and/or filtering information.    

Either the value '0' or the port number of the
port from which a frame must be received in order
for this entry's filtering information to apply.
A value of zero indicates that this entry applies
on all ports of the bridge for which there is no
other applicable entry.    

When the destination port to which this table entry
applies is a wide area port, this object is used to
identify the wide area address to use when forwarding
packets to this destination.  The type of address can
be determined by the ifType value corresponding to
the port identified by dot1dStaticAllowedToGoTo or
dot1dTpFdbPort.  If the port is not a wide area port,
this object will contain a zero length string.

The representation of the addresses will follow the
convention used in standard MIBs.  For example,
Frame Relay DLCI's will be encoded as binary numbers
and placed in the OCTET STRING.  X.25 addresses, on
the other hand will be encoded as ASCII characters
[0..9], with each octet of the OCTET STRING containing
the ASCII representation of one digit.    

This table is an extension of the dot1dTpFdbTable
from the Bridge MIB, rfc1286.  One additional
column has been defined to identify the proper wide
area address when bridging over a wide area port.    

An extension to the dot1dTpFdbTable from rfc1286.    

A unicast MAC address for which the bridge has
forwarding and/or filtering information.    

When the port to which this table entry applies
is a wide area port, this object is used to
identify the wide area address to use when forwarding
packets to this destination.  The type of address can
be determined by the ifType value corresponding to
the port identified by dot1dTpFdbPort.  If the port
is not a wide area port, this object will contain
a zero length string.    

This table is an extension of the dot1dBasePortTable
from the Bridge MIB defined in RFC1286.  This table
contains generic information and control facilities
for every port that is associated with the bridge.
Transparent, source-route, and srt ports are included.    

Each entry in this table contains information and
controls for a specific bridge port.    

The port number of the port for which this
entry contains bridge management information.    

This identifies the SMDS Group Address that
is used by the bridge to transmit packets to
all the other bridges identified by this SMDS
Group Address.  This address is used as the SMDS
destination address when transmitting spanning tree
BPDU packets, all bridged broadcast and multicast
packets, and bridged packets containing a destination
address that has not yet been learned.

If the address is less than 8 Octets, the remaining
octets are padded with 0xFF's.

If there is no SMDS Group Address assigned, this object
will return all zeroes.

Note, bridging must be enabled for any sets made to this
object to be affected.    

This object specifies the X25 User ProfileID to be used for
selecting a Virtual Circuit to send Bridged Packets. Range
is 0..255. If the value specified is 0 then use the DTE Profile
ID    

Possible values are:


transparent, sourceRoute, srtEnabled, 
noBridging

This object controls which type(s) of packets
are bridged.  This has no affect on whether the
bridge participates in either the Spanning Tree
or Source Route Protocols.    

Possible values are:


none, forward, block
                

This object is a security feature that allows the
control of packets sent to specific destinations.
If this object is set to forward (2), only those
packets for destination addresses listed in the static
forwarding table can be forwarded by this port.  If
this object is set to block (3), any packet destined
for an address listed in the static forwarding table is
blocked by this port.  Note, these actions are taken
by this port after it receives a packet from the network.
This does not apply to packets it forwards to the
network.    

Possible values are:


none, forward, block
                

This object is a security feature that allows the
control of packets sent from specific source addresses.
If this object is set to forward (2), this port will
forward only those packets sent from addresses listed
in the static forwarding table for this port.  If this
object is set to block, this port will block every
packet sent by a station whose address is listed
in the static forwarding table for this port.  Note,
these actions are taken by this port after it receives
a packet from the network.  This does not apply to
packets it forwards to the network.    

This object applies to transparent bridging
over an X25 network.  It specifies the protocol
ID to be used in an outgoing X25 call.    

DEPRECATED
This object applies to transparent bridging
over an X25 network.  It allows the specification
of the maximum number of packets that can be
queued on any single virtual circuit to a
specific DTE neighbor when the virtual circuit
on the X25 port is congested.

NOTE: this object is no longer supported by NETBuilders
running sw version 8.0 and greater.    

DEPRECATED
This object allows the specification of the
maximum number of virtual circuits to a
specific DTE that can be established concurrently
for transparent bridging over an x25 network.

NOTE: this object is no longer supported by NETBuilders
running sw version 8.0 and greater.    

DEPRECATED
This object specifies the maximum amount of
time, in minutes, that can elapse when there
is no activity on the x25 virtual circuit to a DTE
before it is cleared.

NOTE: this object is no longer supported by NETBuilders
running sw version 8.0 and greater.    

This object specifies the maximum rate, in
packets per second, at which broadcast and
multicast packets are forwarded through this
port.  If the number of these packets during
a single time interval (specified by
a3ComBrgBLimitTimer) exceeds the number
allowed during that interval, as calculated
from the value of this object, all further
broadcast and multicast packets will be
discarded for the rest of the time interval.

If this object is set to zero, this feature
is disabled for this port.

Note, any changes to this object will only
take affect after the system is rebooted.    

This table specifies the DTE address of each
X25 neighbor that supports transparent bridging.
The bridge will forward to the neighbors defined in
this table all broadcast packets and unknown
unicast packets.    

Each entry contains the DTE address of an X25 neighbor.    

This object is used to add and delete entries
in this table.  See the notes describing
RowStatus at the beginning of this MIB.    

Possible values are:


aging, noAging
                

This object determines whether nodes that have not
transmitted packets for a specified amount of time
are deleted from the forwarding table.  If this
object is set to aging (1), entries in the forwarding
table are removed after dot1dTpAgingTime seconds.
This is useful in environments where nodes may be
moved from one network to another.  Setting this object
to noAging (2), however, improves performance.    

Possible values are:


firewall, noFirewall
                

This object is important when the system is performing
both bridging and routing.  When this is set to
firewall (1), the bridge discards unicast packets
of a protocol that is being routed (other than the
unicast packets addressed to the bridge itself).
If this is set to noFirewall, the bridge forwards
those packets.    

Possible values are:


learn, noLearn
                

This object determines whether the bridge creates
and updates entries in its forwarding tables.    

Possible values are:


forward, noForward
                

This object determines whether the bridge forwards
packets.  This has no effect on other bridging
related functions, such as Spanning Tree, Learning,
and Source Routing.  Setting this object to
noForward (2), allows isolation of the attached
networks for diagnostic purposes.    

Possible values are:


enable, disable
                

This object enables the bridge to forward
AppleTalk packets between Ethernet, FDDI, and
token ring networks.  The AppleTalk packets
require encapsulation over FDDI networks.
If AppleTalk packets are to be translated
the same way as other Ethernet packets are
translated, this parameter must be disabled (2).

If this object is enabled, the original format
of both AT-1 (Ethernet) and AT-2 (SNAP) packets
are preserved when bridging between Ethernets
over an FDDI backbone.  If this is disabled,
AT-2 packets are converted to Ethernet format
before going across the FDDI backbone.    

Possible values are:


other, dynToStatic, delStatic, delDyn
                

This object is used to trigger actions taken on the
static forwarding table.  When this object is set to
dynToStatic (2), all dynamically learned entries
in the forwarding table are marked static.  When
this object is set to delStatic (3), all statically
learned entries are deleted.  When this object is set to
delDyn (4), all dynamically learned entries are deleted.
When a GET request is received for this object, the
value other (1) is returned.    

This object returns the size of the bridge
forwarding table in units of 2^(9+n) where
n is the value of this object.  Thus, if this
object has the value 2, then the bridge
forwarding table has 2048 entries.

If this value is changed, via a set, the
new value will take affect only after the
bridging service is disabled and re-enabled.    

Possible values are:


disabled, timer400ms, timer600ms, 
timer800ms, timer1000ms

This object is used to select the broadcast limit
feature sample interval.  That is, this object
contains the value of the time interval over which
the number of broadcast packets per second are calculated.
If that number exceeds the value of a3ComBrgBroadCastLimit
for a particular port, the bridge will stop forwarding
all broadcast packets on that port for the rest of
the time interval.    

This is the multicast MAC address used by bridges
running the Spanning Tree Protocol.    

Possible values are:


enabled, disabled
                

This object is used to enable/disable the Spanning
Tree Protocol for the bridge as a whole.    

Possible values are:


hopReduce, noHopReduce
                

This object determines whether the bridge
considers the number of hops needed to forward
a packet to the root bridge when it selects
a root port.  If hopReduce is selected, the
bridge increases its root path cost by 1.  If
noHopReduce is selected and two ports have the
same root path cost, the port that offers the least
number of hops might not be chosen as the root port.    

Possible values are:


ieee, passiveBridging
                

This object defines the mode of source routing
in use on the bridge.  If ieee (1) is selected,
explorer frames are modified and the forwarding
path of the specifically routed frames is
determined from the routing information (RI) field.
If passiveBridging (2) is selected, the source
routed frames are bridged across the spanning
tree as if they were transparent frames without
examining or updating the RI field.  When in
passiveBridging mode, the same ring number should
be assinged to all active ports of the bridge.    

This table contains port specific source routing
information.    

Each entry contains a set of information applied
to a specific bridge port.    

This identifies the bridge port to which
the other objects in this entry apply.    

This object contains the maximum number of
routing descriptors (ie, hop count) for Spanning
Tree Explorer frames.    

This object contains the maximum number of
routing descriptors (ie, hop count) for All
Routes Explorer frames.    

This parameter specifies the time interval,
in minutes, that an inactive route entry can
reside in the source routing table.    

This parameter determines the minimum access
priority used for outoing frames on this port.
End systems usually have a low access priority
while bridges have a medium priority.  This
allows bridge, which typically handle larger
volumes of data, to get the token faster than
end systems.  If the user priority of the frame
is greateer than the minumum access priority, the
user priority is used as the access priority.  The
user priority of the frame is determined by the
access priority of the incoming frame.    

A table containing mappings between Ring Number,
Bridge Number, and Wide Area Addresses.  This
information is learned from Explorer Frames sent
by end stations.    

Each entry contains a single Ring Number, Bridge
Number, Wide Area Address mapping.    

This identifies the bridge port that is connected
to the ring identified by a3ComBrgSrWAringNum.    

This identifies a specific wide area network.  When
a source route frame is bridged to this ring number,
and to the bridge identified by a3ComBrgSrWAbrgNum,
the Wide Area Address identified by the corresponding
instance of a3ComBrgSrWAddress is used to forward the
frame to the proper bridge.    

This identifies the bridge associated with the
Wide Area Address identified by a3ComBrgSrWAddress.    

This identifies the Wide Area Address associated
with a specific ring number and bridge number.  These
are identified by the corresponding instances of
a3ComBrgSrWAringNum and a3ComBrgSrWAbrgNum.    

This parameter is used whenever SRTG is bridging packets
between TB and SR domains.  Before forwarding packets from
a TB domain, SRTG specifically adds this 'virtual' ring
number and its own bridge number to the source route
information of the destination station retrieved from the
SRDB.  Thus from a source routing station's point of
view, the entire transparent bridge LAN appears as a single
source routed ring.  If this parameter has the value 0,
no virtual ring number is added.    

Each entry in this table control the behavior of
the SRT Gateway feature for a specific port.    

This identifies the bridge port to which the
other objects in this entry apply.    

Possible values are:


enable, disable
                

This parameter is used to enable or disable
the SRT Gateway feature for this port.    

Possible values are:


ieeeMode, etherMode
                

This parameter is used to control how packets using
Token Ring LLC-based protocols are converted when
bridged to Ethernet LANs.  If this object has the
value 'ieeeMode', those packets will be translated
into IEEE 802.2 frames.  Otherwise, they will be
converted into Ethernet Version II format.  Note,
if the type of frame used by the destination is
known (ie, if autoMode is selected and the station
is known), this parameter is ignored and the previously
seen frame type is used.    

Possible values are:


autoMode, noAutoMode
                

This parameter specifies whether or not the encapsulation
format of each end stations is stored.    

This table specifies whether end system source routing
is enabled on for each port on the system.  There are
separate controls for each protocol that may use source
routing.    

This identifies the bridge port to which the
other objects in this entry apply.    

Possible values are:


appleTalk, noAppleTalk
                

This specifies whether route discovery is initiated
for AppleTalke end system packets.  This discovery
process occurs when a route to the end system does
not exist in the local source routing table.  If this
is set to noAppleTalk, all AppleTalk end system
packets are sent as transparent frames.    

Possible values are:


clnp, noClnp
                

This specifies whether route discovery is initiated
for CLNP end system packets.  This discovery
process occurs when a route to the end system does
not exist in the local source routing table.  If this
is set to noClnp, all CLNP end system packets are
sent as transparent frames.    

Possible values are:


decNet, noDecNet
                

This specifies whether route discovery is initiated
for DECNET end system packets.  This discovery
process occurs when a route to the end system does
not exist in the local source routing table.  If this
is set to noDecNet, all DECNET end system
packets are sent as transparent frames.    

Possible values are:


dlTest, noDlTest
                

This specifies whether route discovery is initiated
for DlTest end system packets.  This discovery
process occurs when a route to the end system does
not exist in the local source routing table.  If this
is set to noDlTest, all DlTest end system
packets are sent as transparent frames.    

Possible values are:


ip, noIp
                

This specifies whether route discovery is initiated
for IP end system packets.  This discovery
process occurs when a route to the end system does
not exist in the local source routing table.  If this
is set to noIp, all IP end system packets are sent
as transparent frames.    

Possible values are:


ipx, noIpx
                

This specifies whether route discovery is initiated
for IPX end system packets.  This discovery
process occurs when a route to the end system does
not exist in the local source routing table.  If this
is set to noIpx, all IPX end system packets are sent
as transparent frames.    

Possible values are:


llc2, noLlc2
                

This specifies whether route discovery is initiated
for LLC2 end system packets.  This discovery
process occurs when a route to the end system does
not exist in the local source routing table.  If this
is set to noLlc2, all LLC2 end system packets are sent
as transparent frames.    

Possible values are:


vines, noVines
                

This specifies whether route discovery is initiated
for Vines end system packets.  This discovery
process occurs when a route to the end system does
not exist in the local source routing table.  If this
is set to noVines, all Vines end system
packets are sent as transparent frames.
