Tag VLAN/ Tag and un-tag function
Tag and un-tag function
IP178C inserts or removes a tag of a frame if tagging/ un-tagging function is enabled. The operation is
illustrated as follows. The tag information is defined in MII register 30.3~30.11 and EEPROM register
6~22.

Tag VLAN
If tag VLAN function is enabled (MII register 30.13[3] TAG_VLAN_EN is logic high), IP178C forwards a
packet according to MAC address table and one of the sixteen VLAN output port masks, defined in MII
register 30.14~30.29. One of the sixteen VLAN output mask is selected by VID index, which is four bits
selected from VID field in a tag. VID index is defined in MII register 30.13[2:0] VID_SEL. For example,
VLAN output port mask 1 is selected if VID index selected by VID_SEL is equal to 1.
IP178C handles an un-tagged packet using the default VLAN tag value of its source port. A packet with
VID equal to 12’b0 will be handled as un-tag frame.
