ngress filtering rules which can be applied to the
Ingress Filtering Rule 1 is “forward only packets with VID matching

fram Hybrid.
arameter description:
Port 1-16:
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 R
abled, 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 100 and port 1 is not member of
VLAN 100, the packet will be dropped.
