5 Configuration D-Link Web Smart Switch User Manual
shared ports and the set of ports to be separated from the other VLANs (for example, port 6 and 7
respectively). Therefore we have three VLANs that share some common ports, but their original
membership ports are still separated from each other (for example, port 5, 6, and 7).
The VLAN settings of this example are:
VLAN 1: default VLAN 1, including all ports with untagged.
VLAN 2: Member ports are untagged port 5, 15-18, 20.
VLAN 3: Member ports are untagged port 6, 15-18, 20.
VLAN 4: Member ports are untagged port 7, 15-18, 20.

3. Configuring the PVID of access VLAN
Configure the PVID setting located at the bottom of the VLAN configuration page. The user needs to
set the shared set of ports as PVID 1, and the other separated groups of ports (for example, port 5, 6,
and 7) as PVID 2, 3 and 4 respectively.
The purpose of assigning PVID is to make sure the untagged packets will be transmitted correctly.
Figure 66 – Configuration > 802.1Q VLAN > Asymmetric VLAN – Assign PVID
After configuration, the user will be able to share the network resources set on the shared group of ports
(nominated as PVID 1), with both smaller subsets of VLANs (nominated PVID 2, 3 and 4). However, VLAN 2,
3 and 4 groups are incapable of sharing information with each other directly. Click Example to see the
example to configure asymmetric VLAN in larger networks.

table will be reset to default.
Configuration > 802.1Q Management VLAN
The 802.1Q Management VLAN setting allows you to transfer the authority of the switch from the default
VLAN to others created by users. This allows managing the whole network more flexible.
By default, the Management VLAN is disabled. You can select any existing VLAN as the management VLAN
when this function is enabled. There can only be one management VLAN at a time.
