Click [Port PVID Setting]
This page is used to setup PVID and Tag mode for each port as follows:
PVID : The valid value range is 1 ~ 4095. The setting value is used for the
following purposes:
1. It is used as VLAN group lookup index when an untagged packet is
received. The least four bits (bit 3~bit 0) of the PVID setting of the
input port is used for mapping to one VLAN group.
2. It is used to be inserted into the packet as VID when an untagged
packet is received and forwarded to a Tag port.
