3.3.2 FDB Conflicting Traps
IVD will transmit a trap packet to central manager when any MAC address moves from one port to
another port.
3.3.3 MAC Address Tracking
IVD can be configured to track a global list of MAC addresses. When these MAC addresses move
from one port to another port, a trap is generated. Whether packets from a particular bridge port
should be subjected to this tracking is configurable. This may be used to prevent denial of service
from certain MAC addresses.
3.3.4 Access Control List by MAC address
This feature can be configured by per-port. It also supports a MAC address deny list, the
application of the MAC address deny list can be enabled/disabled on a per bridge port basis.
3.3.5 Access Control List by IP Address
This feature still can be configured by per-port, and enabled/disabled on a per bridge port basis.
3.4 Packet Filtering
This function is provided for users to setup some rules to filter the specific packets while receiving
packets from logical ports.
IVD supports for rule-based packet filtering, it can be used to implement filtering required of
NetBEUI, NetBIOS, DHCP, 802.1x and other protocols.
3.4.1 Filtering Modes
IVD supports for independent rule ordering and rule ID. It means that rule ID no longer determines
the order in which the rule is applied. The rule can be modified easily; users can replace a rule
sequence of a stage on an interface by another sequence in one step.
Moreover, IVD also supports for capturing unicast and multicast packets that fail lookup in the
forwarding database is provided. Users may write their own applications to terminate and act on
this information. On the other side, it also supports for capturing packets coming to Control Plane
that do not match any registered filter.
IVD supports configurable Ethertype filter for upstream direction.
IVD supports configurable MAC filter for upstream direction.
IVD supports configurable Broadcast (blocking/enabling) filter for downstream direction.
IVD supports configurable Multicast (enabling, disabling, prefix specific enabling) filter for
upstream direction.
