Managing Packet Flow through the DockLINK

Managing Packet Flow through the DockLINK

The DockLINK can selectively allow or disallow traffic to or from the 10BaseT Network Interface Card and the RadioLAN wireless network. Proper packet flow management improves the speed of the RadioLAN wireless network by eliminating unwanted network traffic.

The DockLINK is set for optimum performance by default. Only advanced users with special circumstances should use the entries on MAC Filter screens. Figure 22 shows the 10BASET PORT MAC FILTER – EDIT page. The DockLINK contains and manages two identical filtering databases:

∙ 10BaseT Port MAC Filter List

∙ Radio Port MAC Filter List

Figure 22: MAC Address Table

Each of these databases allows you to add up to 32 MAC Addresses and to allow or disallow the receipt or transmission of data packets to specified MAC Addresses.
