Address (DA) table. The Switch will compare all the incoming
packets and checks if the DA is within the sixteen MAC addresses
of the DA table. If there is a match between the packet's DA and
the sixteen MAC addresses, the packet is then "forwarded" to the
intended for MAC address.
Otherwise, the packet will be
discarded.
User Defined Table
You can compile your own User Defined Table using the
EtherSwitch Console Program which allows you to input sixteen
MAC addresses for each of the five ports.
The Console
management program can be accessed via the RS-232 DCE port
located in the front panel of the DES-3205. These MAC addresses
form the basis for explicit forwarding and can be used for filtering
and security of the system. Filtering can be viewed as the process
of discarding, examining, forwarding and blocking of packets as
they go through the Switch. Security can be illustrated when you
have specified the MAC addresses that are allowed to be forwarded
or blocked depending on the filter setting. Therefore, if a packet is
received with a MAC address that is not recorded within the
sixteen MAC address table (your user defined table). The MAC
address is considered an undefined address, and the packet will be
automatically discarded. the Switch does not forward packets with
undefined MAC addresses.
This procedure will speed up and
enhance the processing of packets and thereby give you (the user)
the benefit of enhance performance.
Adding MAC Addresses to the Table
In order to add entries to the user defined MAC address table, first
connect a PC (or terminal) to the RS-232 port of the Switch. This
begins the VT100 terminal emulation process.
The VT100
terminal emulation software can be found in Microsoft Windows or
