[. . . ] ADDENDUM 0 FILTERING DATA BASE MAC ADDRESS CONFIGURATION Introduction In order to boost the performance of the DES-3205, the Filtering Data Base is used to accomplish this task by: Explicitly forwarding user defined MAC addresses. Letting the user define sixteen MAC addresses for each port. Explicit Forwarding The DES-3205 Switch comes with an explicit forwarding feature. This feature can be used for security as well as other aspects in the management of the Switch. [. . . ] 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. 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. The VT100 terminal emulation software can be found in Microsoft Windows or any other communication software. For more information about the RS-232 port and the VT100 terminal emulation process, see the Out-of-Band Management of this user's guide. After a successful connection of the PC to the RS-232 port of the Switch. At the setup screen, verify that all settings are in accord with the settings shown on the front panel of the DES-3205 Switch or the "DCE/DTE line setting" in the Out-of-Band Management section of this user's guide. The settings should be as follows: Baud Rate Parity Data bits Stop bits 19200 None 8 1 Verify that these settings are correctly entered in each field. Incorrect settings could mean that VT100 terminal emulation communication with the Switch might not be possible. Pressing the Enter (Return) key should give you the EtherSwitch Console Program main menu screen: From this screen, perform the following steps to add entries to your user defined MAC address table: 1. Press the Tab key until you are at the "Filtering Data Base" selection of the main menu. The Tab key moves the highlighting down from field to field; while, the Backspace key moves the highlighting up from field to field. Also, the up and down arrow keys moves the highlighting and cursor up and down as appropriate. Move the highlighting to the Port Number field and type in the desired port you are willing to set. Note that the Filter State automatically changes to "Disable" and all MAC addresses are cleared and ready for your input. Move the highlighting to the Filter State field and toggle between either "Disable, Forwarding or Blocking. " To toggle within this field, you must use the Space bar. [. . . ] This selection of the filter state will compare all incoming packets to check if it matches one of the sixteen MAC addresses specified by the user. These entries must be accurate in order for proper management and handling of packets. Also, it is not required that all of the sixteen MAC addresses be used. [. . . ]
