4-2-5. PVID Configuration
Function name:
PVID Configuration
Function description:
In VLAN Port VID Setting, user can input VID number to each port. The range of VID
number is from 1 to 4094. User also can choose ingress filtering rules to each port. There
are two ingress filtering rules which can be applied to the switch. The Ingress Filtering
Rule 1 is “forward only packets with VID matching this port’s configured VID”. The Ingress
Filtering Rule 2 is “drop untagged frame”.
Parameter description:
Port 1-12:
Port number.
PVID:
This PVID range will be 1-4094. Before you set a number x as PVID, you have to
create a Tag-based VLAN with VID x. For example, if port x receives an untagged
packet, the switch will apply the PVID (assume as VID y) of port x to tag this packet,
the packet then will be forwarded as the tagged packet with VID y.
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 given port is a member of the VLAN on which the received packet
belongs to, to determine forward it or not. 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 yes, 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 frame. If the former is the case, then the
packets with tagged or untagged will be processed. If the later is the case, only the
packets carrying VLAN tag will be processed, the rest 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.
But if the PVID of port 1 is not 100, the packet will be dropped.
Tag:
This is an egress rule of the port. Here you can choose untag or tag. Tag means the
outgoing packets must carry VLAN tag header, just tick the check box (
)
. Untag
means the outgoing packets carry no VLAN tag header.
