To configure MAC filter settings:
1. To configure a new MAC filter:
a. Select Create Filter from the MAC Filter menu. If no filters have been configured, this
is the only option available.
b. From the VLAN ID menu, select the VLAN to use with the MAC address to fully
identify packets you want filtered. You can change this field only when the Create
Filter option is selected from the MAC Filter menu.
c. In the MAC Address field, specify the MAC address of the filter in the format
00:01:1A:B2:53:4D. You can change this field when you have selected the Create
Filter option.
You cannot define filters for the following MAC addresses:
• 00:00:00:00:00:00
• 01:80:C2:00:00:00 to 01:80:C2:00:00:0F
• 01:80:C2:00:00:20 to 01:80:C2:00:00:21
• FF:FF:FF:FF:FF:FF
d. Click the orange bar under the Source Port Members heading to display the
available ports. Select the port(s) to include in the inbound filter. If a packet with the
MAC address and VLAN ID you specify is received on a port that is not in the list, it
will be dropped.
e. Click the orange bar under the Destination Port Members heading to display the
available ports. Select the port(s) to include in the outbound filter. Packets with the
MAC address and VLAN ID you selected will be transmitted only out of ports that are
in the list. Destination ports can be included only in the Multicast filter.
2. To delete a configured MAC Filter, select it from the menu, and then click Delete.
3. Click Cancel to cancel the configuration on the screen and reset the data on the screen to
the latest value of the switch.
4. If you make changes to the page, click Apply to apply the changes to the system.
