Note:
The industrial managed switch's default is to assign all ports to a single 802.1Q
VLAN named DEFAULT_VLAN. As a new VLAN is created, the member ports assigned
to the new VLAN are removed from the DEFAULT_ VLAN port member list. The
DEFAULT_VLAN has a VID = 1.
This section has the following items:
VLAN Port Configuration

Private VLAN
Creates/removes primary or community VLANs
Port Isolation
Enables/disablse port isolation on port
MAC-based VLAN

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 permitting relocation of 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 email), or multicast groups (used for multimedia applications such as
videoconferencing).
VLANs provide greater network efficiency by reducing broadcast traffic, and permit
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
