6.4.2 MAC Filtering

NOTE: This function is only available when in bridge mode. PPPoE, PPPoA,

IPoA and MER use IP Filtering (pg. 49) to perform a similar function.

Each network device has a unique 48-bit MAC address. This can be used to filter

(block or forward) packets based on the originating device. MAC filtering policy

and rules for the CT-5611TC can be set according to the following procedure.

The policy FORWARDED means that all MAC layer frames will be FORWARDED

except those matching the rules specified in the following table. BLOCKED

means that all MAC layer frames will be BLOCKED except those matching the

rules specified in the following table. The default policy is FORWARDED. This

can be changed by clicking the Change Policy button.

Choose Add or Remove to configure MAC filtering rules. The following screen

will appear when you click Add. Create a filter to identify the MAC layer frames

by specifying at least one condition below. If multiple conditions are specified, all

of them must be met. Click Save/Apply to save and activate the filter rule.
