6.4.2 MAC Filtering
NOTE: This option is only available in bridge mode. Other modes use IP Filtering
(pg. 58) 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-5364A can be set according to the following procedure.
The MAC Filtering Global Policy is defined as follows. FORWARDED means that all
MAC layer frames will be FORWARDED except those matching the MAC filter rules.
BLOCKED means that all MAC layer frames will be BLOCKED except those
matching the MAC filter rules. The default MAC Filtering Global policy is
FORWARDED. It 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.
