3.3.3 Ingress Default Tag Per Port Setting

Each port can be configured with one Ingress Default Tag. This ingress port default tag is used when ingress port is in Tag-ignoremode or for the received untagged packets in Tag-awaremode. The Ingress Default Tag includes PVID, CFI and User Priority configuration.

When Ingress port default tag is used, it is copied as packet associated Packet Tag Information for VLAN classification. The PVID is used as index to one VLAN group in VLAN group table.

3.3.4 Packet Tag Information

Under VLAN process, every packet is associated with one Packet Tag information in packet forward- ing operation. The tag information includes VID, CFI and User Priority data and is used for two purposes:

•The VID in tag is used as index for VLAN classification.

•The tag is used for egress tag insertion if egress tagging is enabled.

The following table lists how the Packet Tag information is generated:

Tag Aware setting	Received Packet Type
Tag-ignore	Untagged packet
Tag-ignore	Priority-tagged packet
Tag-ignore	VLAN-tagged packet
Tag-aware	Untagged packet
Tag-aware	Priority-tagged packet
Tag-aware	VLAN-tagged packet
