b) Port VID
Use this option to configure the VLAN ID for all untagged frames of the port.
Example : if the default PVID of port 2 is 3, all untagged frames of port 2 belong to
VLAN3. The default PVID for all ports is 1. If the user wants to change a device that does
not support tagged frames and add it to a VLAN, this feature can be applied. Each port
can only have one untagged VLAN.
Ingress Filter
If the port belongs to the VLAN, the frames that belong to the VLAN will be forwarded.
There are two ingress rules:
Ingress rule 1: only forward the frames whose VID is appropriate to the ports.
Ingress rule 2 : drop the untagged frames.
Advanced Info
The user can configure the VLAN in two ways: dividing the VLAN on one switch or on
different switches in ring network. It is easy to divide a VLAN on one switch, and three
VLAN modes can be applied, by assigning different VIDs to the port.
The user needs to apply 802.1Q GVRP-aware or GVRP-unaware VLAN when dividing a
VLAN on ring network with different switches.
