Custom Filtering Table
The Custom Filtering Table contains filtering information
configured into the Switch by (local or network) management
specifying the set of ports to which packets received from specific
ports and containing specific destination addresses that are
allowed to be forwarded. You can use the Custom Filtering Table
for network security purposes thereby aging out or discarding
unwanted addresses from the Forwarding Table; furthermore, you
can use it for explicit forwarding by speeding up the process of
packet forwarding.
Dynamic Filtering and Static Filtering are among the two
important features of the Custom Filtering Table. They are
defined here briefly as follows.
Dynamic Filtering
is defined when
a dynamic entry is created by the Learning Process as a result of
observation of network traffic in the Filtering Database.
Static
Filtering
is defined as static entries that may be added and
removed from the Filtering Database by the user. They are not
automatically removed by any timeout mechanism.
