3-6-3. PVID
Function name:
PVID
Function description:
In PVID 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 rule (Rule 2)
to each port. The Ingress Filtering Rule 2 is “drop untagged frame”. While Rule
2 is enabled, the port will discard all Untagged-frames.

Parameter description:
Port 1-26:
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.
Default Priority:
It bases on 802.1p QoS and affects untagged packets. When the packets
enter the switch, it would get the priority precedence according to your
Default Priority setting and map to 802.1p priority setting in QoS function.
For example, while you set Default Priority of port 2 with 2 and transmit
untagged packets to port 2, these packets will own priority 2 precedence
due to your default 802.1p Priority Mapping setting in QoS function and
be put into Queue 1.
