To configure the MAC Address Table:
1. Click Configuration, MAC Table.
2. Change the address aging time if required.
3. Specify the way in which MAC addresses are learned on any port.
4. Add any required static MAC addresses by clicking the Add New Static
Entry button, entering the VLAN ID and MAC address, and marking the
ports to which the address is to be mapped.
5.
Click Save.

IEEE 802.1Q VLAN S
In large networks, routers are used to isolate broadcast traffic for each
subnet into separate domains. This switch provides a similar service at
Layer 2 by using VLANs to organize any group of network nodes into
separate broadcast domains. VLANs confine broadcast traffic to the
originating group, and can eliminate broadcast storms in large networks.
This also provides a more secure and cleaner network environment.
An IEEE 802.1Q VLAN is a group of ports that can be located anywhere in
the network, but communicate as though they belong to the same physical
segment.
VLANs help to simplify network management by allowing you to move
devices to a new VLAN without having to change any physical connections.
VLANs can be easily organized to reflect departmental groups (such as
Marketing or R&D), usage groups (such as e-mail), or multicast groups
(used for multimedia applications such as videoconferencing).
VLANs provide greater network efficiency by reducing broadcast traffic, and
allow you to make network changes without having to update IP addresses
or IP subnets. VLANs inherently provide a high level of network security
