Managing Packet Flow Through the CPU

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

The CPU is set for optimum performance by default. Only advanced users with special circumstances should use the entries on MAC Filter screens.

Figure 36 shows the 10BASET PORT MAC FILTER – EDIT PAGE. The CPU contains and manages two identical filtering databases:

∙10BaseT Port MAC Filter List

∙Radio Port MAC Filter List

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 MACFigure 36: MAC Address Table Addresses.
