DWS-1008 User's Manual
A DWS-1008 switch switches traffic at Layer 2 among ports in the same VLAN. For example,
suppose you configure ports 4 and 5 to belong to VLAN 2 and ports 6 and 7 to belong to
VLAN 3. As a result, traffic between port 4 and port 5 is switched, but traffic between port 4
and port 6 is not switched and needs to be routed by an external router.
802.1Q Tagging
The tagging capabilities of the switch are very flexible. You can assign 802.1Q tag values on
a per-VLAN, per-port basis. The same VLAN can have different tag values on different ports.
In addition, the same tag value can be used by different VLANs but on different network
ports.
If you use a tag value, D-Link recommends that you use the same value as the VLAN
number. MSS does not require the VLAN number and tag value to be the same, but some
other vendors' devices do.
Note: Because the default VLAN (VLAN 1) might not be in the same subnet on each switch,
D-Link recommends that you do not rename the default VLAN or use it for user traffic.
Instead, configure other VLANs for user traffic. Do not assign the same VLAN multiple times
using different tag values to the same network port. Although MSS does not prohibit you
from doing so, the configuration is not supported.
Configuring a VLAN
You can configure the following VLAN parameters:
• VLAN number
• VLAN name
• Port list (the ports in the VLAN)
• Per-port tag value (an 802.1Q value representing a virtual port in the VLAN)
