2. Click Apply.

The MAC address lists of PCs in the network are saved on the ONU. Configuring MAC filter rules enables the PCs that conform to the rules to access the Internet service or disables the PCs that do not conform to the rules to access the Internet service. A PC may have more than one IP addresses but can have only one unique MAC address. Therefore, configuring MAC filter rules effectively controls the Internet service access rights of PCs in a LAN.

Table 8-7 describes the parameters related to the MAC filter.
