2.5.6.2. Static MAC Address

When you add a static MAC address, it remains in the switch's address table, regardless of whether the

device is physically connected to the switch. This saves the switch from having to re-learn a device's

MAC address when the disconnected or powered-off device is active on the network again.

1.

At the main menu, click administrator

Æ

Static MAC Address.

2.

In the MAC address box, enter the MAC address to and from which the port should permanently

forward traffic, regardless of the device’s network activity.

3.

In the Port Number box, enter a port number.

4.

If tag-based (IEEE 802.1Q) VLANs are set up on the switch, static addresses are associated with

individual VLANs. Type the VID (tag-based VLANs) to associate with the MAC address.

5.

Click the Add.

6.

Click the “Prev 50” will list the previous 50 MAC addresses.

7.

Click the “Top” will refresh the list from the first entry.

8.

Click the “Next 50” will list the next 50 MAC addresses.

2.5.6.3 MAC filtering

MAC address filtering allows the switch to drop unwanted traffic. Traffic is filtered based on the

destination addresses.

1.

In the MAC Address box, enter the MAC address that wants to filter.

2.

If tag-based (802.1Q) VLAN are set up on the switch, in the VLAN ID box, type the VID to associate

with the MAC address.

3. Click the Add.

4.

Choose the MAC address that you want to delete and then click the Delete.

5.

Click the “Prev 50” will list the previous 50 MAC addresses.

6.

Click the “Top” will refresh the list from the first entry.

7.

Click the “Next 50” will list the next 50 MAC addresses.

2.5.7. VLAN configuration

A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain. It allows you to

isolate network traffic so only members of the VLAN receive traffic from the same VLAN members.

Basically, creating a VLAN from a switch is logically equivalent of reconnecting a group of network

devices to another Layer 2 switch. However, all the network devices are still plug into the same switch

physically.

The

24+2G

switch supports port-based, 802.1Q (tagged-based) and protocol-base VLAN in web

management page. In the default configuration, VLAN support is disabling.

±

Support Port-based VLAN

Packets can only be broadcast among members of the same VLAN group. Note all unselected ports are

treated as belonging to another single VLAN. If the port-based VLAN enabled, the VLAN-tagging is

ignored.

Support Tag-based VLAN (IEEE 802.1Q VLAN)

Tagged-based VLAN is an IEEE 802.1Q specification standard. Therefore, it is possible to create a

VLAN across devices from different switch venders. IEEE 802.1Q VLAN uses a technique to insert a

“tag” into the Ethernet frames. Tag contains a VLAN Identifier (VID) that indicates the VLAN numbers.

±

Support Protocol-based VLAN

In order for an end station to send packets to different VLANs, it itself has to be either capable of tagging

packets it sends with VLAN tags or attached to a VLAN-aware bridge that is capable of classifying and

tagging the packet with different VLAN ID based on not only default PVID but also other information

about the packet, such as the protocol.

24+2G switch will support protocol-based VLAN classification by means of both built-in knowledge of

layer 2 packet formats used by selected popular protocols, such as Novell IPX and AppleTalk’s Ether

Talk, and some degree of programmable protocol matching capability.

2.5.7.1. Port Based VLAN

1.

Click Add to create a new VLAN group.

2.

Enter the VLAN name, group ID and select the members for the new VLAN.

3. Click Apply.

4.

If there are many groups that over the limit of one page, you can click the “Next Page” to view other

VLAN groups.

NOTE:

If the trunk groups exist, you can see it (ex: TRK1, TRK2…) in select menu of ports, and you

can configure it is the member of the VLAN or not.
