Special Tagging Mode
Special Tagging Mode is designed for spanning tree protocol IGMP snooping and is flexible for use in other
applications. Special Tagging, similar to 802.1Q Tagging, requires software to change network drivers to
insert/modify/strip/interpret the special tag. This mode is enabled by setting both register 11 bit [0] and register 48 bit [2]
to ‘1’.
802.1Q Tag Format
Special Tag Format
TPID (tag protocol identifier, 0x8100) + TCI
STPID (special tag identifier, 0x810 +
4 bit for “port mask”) + TCI
Table 15. Special Tagging Mode Format
The STPID is only seen and used by the port 3 interface, which should be connected to a processor. Packets from the
processor to the switch’s port 3 should be tagged with the STPID and the port mask, defined as follows:
“0001”, forward packet to port 1 only
“0010”, forward packet to port 2 only
“0011”, broadcast packet to port 1 and port 2
Packets with normal tags (“0000” port masks) will use KSZ8893FQL internal MAC table look-up to determine the
forwarding port(s). Also, if packets from the processor are not tagged, the KSZ8893FQL will treat them as normal
packets and use internal MAC table lookup to determine the forwarding port(s).
The KSZ8893FQL uses a non-zero “port mask” to bypass the internal MAC table lookup result, and override any port
setting, regardless of port states (disable, blocking, listening, and learning). The table below shows the processor to
switch egress rules when dealing with STPID.
Ingress Tag Field
TX port “tag
insertion”
TX port “tag
removal”
Egress Action to Tag Field
(0x810 + port mask)
0
- Modify tag field to 0x8100
- Recalculate CRC
- No change to TCI if not null VID
- Replace VID with ingress (port 3) port VID if null VID
(0x810 + port mask)
0
1
- (STPID + TCI) will be removed
- Padding to 64 bytes if necessary
- Recalculate CRC
(0x810 + port mask)
1
0
- Modify tag field to 0x8100
- Recalculate CRC
- No change to TCI if not null VID
- Replace VID with ingress (port 3) port VID if null VID
(0x810 + port mask)
1
- Modify tag field to 0x8100
- Recalculate CRC
- No change to TCI if not null VID
- Replace VID with ingress (port 3) port VID if null VID
Not Tagged
Don’t care
- Determined by the Dynamic MAC Address Table
