VLAN Routing
You can configure the D-Link DWS-4000 Series switch with some ports supporting VLANs and some supporting
routing. You can also configure the software to allow traffic on a VLAN to be treated as if the VLAN were a
router port.
When a port is enabled for bridging (default) rather than routing, all normal bridge processing is performed
for an inbound packet, which is then associated with a VLAN. Its MAC Destination Address (MAC DA) and VLAN
ID are used to search the MAC address table. If routing is enabled for the VLAN, and the MAC DA of an inbound
unicast packet is that of the internal bridge-router interface, the packet is routed. An inbound multicast packet
is forwarded to all ports in the VLAN, plus the internal bridge-router interface, if it was received on a routed
VLAN.
Since a port can be configured to belong to more than one VLAN, VLAN routing might be enabled for all of the
VLANs on the port, or for a subset. VLAN Routing can be used to allow more than one physical port to reside
on the same subnet. It could also be used when a VLAN spans multiple physical networks, or when additional
segmentation or security is required. This section shows how to configure D-Link DWS-4000 Series Unified
Switch software to support VLAN routing. A port can be either a VLAN port or a router port, but not both.
However, a VLAN port may be part of a VLAN that is itself a router port.
VLAN Routing Configuration
Use the VLAN Routing Configuration page to configure VLAN Routing interfaces on the system.
To display the page, click LAN > L3 Features > Router > VLAN Routing Configuration in the navigation tree.
Figure 207 shows the page when no VLAN routing interfaces exist.
