Field Description
MacAddress
The MAC address used by this bridge, when it
must be referred to, in a unique fashion. It is the
address of one of the Ethernet ports.
No. of Ports
The maximum number of ports that can be
controlled by this bridge.
Base Type
Indicates what type of bridging this bridge can
perform. It is always Transparent Bridging or
STP.
Aging TimeOut
The timeout period, in seconds, for aging out
dynamically learned forwarding information from
CPEs. The value 0 can be configured when
aging is to be stopped.
Slaveaging TimeOut
The timeout period, in seconds, for aging out
dynamically learned forwarding information
learned from the slave device. The
recommended value for this is more than or
equal to the value for dot1dTpAgingTimeOut.
The value 0 can be configured when aging is to
be stopped.
Floodsupport
This is used to specify whether the unknown
unicast packets are to be flooded or not. The
value for this is used along with per vlan
configuration for flood support to determine if
flooding has to be done for unknown unicast
packet.
Bcastsupport
This is used to specify whether the broadcasting
is supported or not. The value for this is used
along with per vlan configuration broadcast
support, to determine if broadcasting has to be
done for the broadcast packet.
Mcastsupport
Used to specify whether the multicast is
supported or not.
Mcastdrop
Used to specify whether the multicast packets
are to be dropped, or to be forwarded, if
multicast is not supported. This is only valid if
dot1dTpMcastSupport is false.
NetAgingTimeout
The timeout period, in seconds, for aging out
dynamically learned forwarding information from
NET side port. This is used only for full bridge
configuration. The recommended value of net
aging timeout should be greater than that of
dot1dTpAgingTimeOut.
Full Bridging Status
This specifies the current state of full bridging on
the bridge. Thebridge can be set to residential
bridging, restricted full bridging or unrestricted
full bridging. In residential bridging, all packets
from a CPE side port are sent to Net side port
without doing a lookup in the forwarding table. In
restricted full bridging, there is a lookup and a
packet coming from a CPE port destined for
another CPE port is dropped. Hence, CPE-CPE
switching is not permitted. In unrestricted full
bridging, all traffic is forwarded based on lookup.
Drop If FDB full status
This specifies if the frame for which learning
could not be done because of forwarding table
limit being reached, is to be dropped. If this is
enabled the frame for which learning could not
be done because of limit exceeded shall be
dropped, else forwarded based on bridge
forwarding logic.This being enabled shall reduce
flooding, as when a response to such a frame
from which learning could not be done shall
come the frame shall be flooded, as the entry for
that unicast address, shall not be found in
forwarding table.
ResidentialNetLearning
This specifies if learning can be done over net
side port for residential bridging. Learning shall
be done on Net port in case of vlan with
