3-3-4. Ports
Function name:
VLAN Port Configuration
Function description:
In VLAN Tag Rule 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”. You can also select the Role of each port as Access, Trunk, or Hybrid.
Parameter description:
Port 1-24:
Port number.
VLAN Aware:
Based on IEEE 802.1Q VLAN tag to forward packet
Ingress Filtering:
Discard other VLAN group packets, only forward this port joined VLAN
group packets
Frame Type:
All: Forward all tagged and untagged packets
Tagged: Forward tagged packets only and discard untagged packets
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.
Role:
This is an egress rule of the port. Here you can choose Access, Trunk or
Hybrid. Trunk means the outgoing packets must carry VLAN tag header.
Access means the outgoing packets carry no VLAN tag header. If
packets have double VLAN tags, one will be dropped and the other will
still be left. As to Hybrid, it is similar to Trunk, and both of them will tag-
out. When the port is set to Hybrid, its packets will be untagged out if the
VID of the outgoing packets with tag is the same as the one in the field of
Untag VID of this port.
Untag VID:
Valid range is 1~4094. It works only when Role is set to Hybrid.
