D-Link DES-3326SR Layer 3 Switch
802.1Q Port Settings
The
Port VLAN ID (PVID)
menu, shown below, allows you to determine whether the switch will share its
VLAN configuration information with other GARP VLAN Registration Protocol (GVRP) enabled switches. In
addition,
Ingress Checking
can be used to limit traffic by filtering incoming packets whose PVID does not
match the PVID of the port.

The following fields can then be set:
Parameter
Description
Unit
Choose the Switch that the VLAN will be created on.
PVID
A
Port VLAN Identifier is a classification mechanism that associates a
port with a specific VLAN and is used to make forwarding decisions
for untagged packets received by the port. For example, if port #2 is
assigned a PVID of 3, then all untagged packets received on port #2
will be assigned to VLAN 3. This number is generally the same as the
VID# number assigned to the port in the Edit 802.1Q VLANs menu
above.
GVRP <
Disabled
>
The
Group VLAN Registration Protocol (GVRP) enables the port to
dynamically become a member of a VLAN.
Ingress Checking
<
Enabled
>
This field can be toggled using the space bar between
Enabled
and
Disabled
.
Enabled
enables the port to compare the VID tag of an
incoming packet with the PVID number assigned to the port. If the two
are different, the port filters (drops) the packet.
Disabled
disables
Ingress filtering.
