Using the Console Interface
To configure an IEEE 802.1Q VLANs, you must do three things:
1.
Decide if you want to enable Ingress Filtering and enable it on the chosen ports. Ingress filtering applied
on a port causes the port to examine all incoming packets and check whether the port itself is a member
of the VLAN on which the packet is destined. This is normally used to keep untagged frames off the
switch, although it can have other uses as well. This setting is configurable for each port in the
Configure Port Ingress Filtering Check
screen.
2.
Define which ports will be active members of the VLAN. A port can transmit packets (coming from the
connected segment) onto only one VLAN. It can receive packets (transmit packets to the connected
segment) on many VLANs. Active VLAN designations are defined by assigning Port VLAN ID numbers
(PVIDs) in the
Configure Default Port VLAN ID
screen. All ports participating in VLANs must have a
PVID.
3.
Define the VLAN itself and assign the ports that will be passive members (able to receive packets with
this VID tag or from a port that has this PVID number). At this point, you need to designate whether a
member port will be a Tagging or Untagging member port. Defining the ports that will be members of a
VLAN, and whether they will Tag or Untag packets is done in the
Configure 802.1Q Static VLAN
Entry
screen.
Choose
Configure 802.1Q VLANs
on the
VLAN Configuration
screen (under
