4.3.3.2 IEEE 802.1Q VLAN

In large networks, routers are used to isolate broadcast traffic for each subnet into separate domains. This Industrial Managed
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 since traffic must pass through
a configured Layer 3 link to reach a different VLAN.
This Industrial Managed Switch supports the following VLAN features:

Up to 255 VLANs based on the IEEE 802.1Q standard

Port overlapping, allowing a port to participate in multiple VLANs

End stations can belong to multiple VLANs

Passing traffic between VLAN-aware and VLAN-unaware devices

Priority tagging
■ IEEE 802.1Q Standard
IEEE 802.1Q (tagged) VLAN is implemented on the Switch. 802.1Q VLAN requires tagging, which enables them to span the
entire network (assuming all switches on the network are IEEE 802.1Q-compliant).
VLAN allows a network to be segmented in order to reduce the size of broadcast domains. All packets entering a VLAN will only
be forwarded to the stations (over IEEE 802.1Q enabled switches) that are members of that VLAN, and this includes broadcast,
