4-2-5. PVID Configuration
Function name:
PVID Configuration
Function description:
From within this menu users can assign a VID number for each port. The range
of VID numbers is from 1 to 4094. You can also choose ingress filtering rules to
each port. There are two ingress filtering rules which can be applied to the
switch. Ingress Filtering Rule 1 is “forward only packets with VID matching this
port’s configured VID”. Ingress Filtering Rule 2 is “drop untagged frame”.
Parameter description:
Port 1-16:
Port number.
PVID:
The PVID range will be from 1-4094. Before you set a PVID number, ensure
that you have created a Tag-based VLAN with VID of the same number. For
example, if port 1 receives an untagged packet, the switch will apply the
PVID (assume VID 5) to tag this packet, the packet then will be forwarded
as a packet tagged with VID 5.
Rule 1:
Forward only packets with VID matching this port’s configured VID. You can
apply Rule 1 as a way to a given port to filter unwanted traffic. In Rule 1, a
given port checks if the received packet is a member of the VLAN which the
received port has been assign via its PVID. For example, if port 1 receives
a tagged packet with VID=100 (VLAN name=VLAN100), and if Rule 1 is
enabled, the switch will check if port 1 is a member of VLAN100. If it is, then
the received packet is forwarded; otherwise, the received packet is dropped.
Rule 2:
Drop untagged frame. You can configure a given port to accept all frames
(Tagged and Untagged) or just receive tagged only frames. If the former is
the case, then packets either tagged or untagged will be processed. If the
later is the case, only packets carrying a VLAN tag will be processed, all
other packets will be discarded.
Note: If Rule 1 is enabled and port 1, for example, receives an untagged packet,
the switch will apply the PVID of port 1 to tag this packet, the packet then will
be forwarded.
Tag:
This is an egress rule applied on data transmitted out of the port. Select
untag or tag. Tag means that the outgoing packets must carry VLAN tag
headers, select the check box (
; ) . Untag means that the outgoing packets
carry no VLAN tag headers.
