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.
Tag Mode
: Setting for each port to be Tag port or Untag port for outbound.
Tag port – All output packets are tagged.
Untag port – All output packets are untagged.
Depending on the received packet type, the rules are applied as follows:
Received untagged packet output to:
Tag port:
The packet is inserted with PVID of the input port as VLAN ID and new CRC.
Untag port: The packet is forwarded with no change.
Received tagged packet output to:
Tag port:
The packet is forwarded with no change.
Untag port: The VID of the packet is removed and forwarded with new CRC.
Note:
1.
When VLAN mode is switched from 802.1Q mode to Port-based mode, the Tag mode settings
for all ports are preset to Untag automatically.
2.
When VLAN mode is changed, current group member ports settings and per port PVID
settings are applied to new VLAN mode.
