VLAN table is used to do VLAN table look up. If 802.1Q VLAN mode is enabled (Register 5, Bit 7 = 1), this table will be
used to retrieve the VLAN information that is associated with the ingress packet. This information includes FID (filter
ID), VID (VLAN ID), and VLAN membership as described below:
Table 11: Format of Static VLAN Table (16 entries)
Bit

R/W
Description
Default

R/W
= 1, the entry is valid
= 0, entry is invalid
1
18-16
Membership
R/W
Specify which ports are members of the
VLAN. If a DA look up fails (no match in
both static and dynamic tables), the packet
associated with this VLAN will be forwarded
to ports specified in this field. E.g. 101
means port 3 and 1 are in this VLAN.
111
15-12
FID
R/W
Filter ID. KS8993F supports 16 active
VLANs represented by these four bit fields.
FID is the mapped ID. If 802.1Q VLAN is
enabled, the look up will be based on
FID+DA and FID+SA.
0x0
11-0
VID
R/W
IEEE 802.1Q 12 bits VLAN ID
0x001
If 802.1Q VLAN mode is enabled, KS8993F will assign a VID to every ingress packet. If the packet is untagged or
tagged with a null VID, the packet is assigned with the default port VID of the ingress port. If the packet is tagged with
non null VID, the VID in the tag will be used. The look up process will start from the VLAN table look up. If the VID is
not valid, the packet will be dropped and no address learning will take place. If the VID is valid, the FID is retrieved.
The FID+DA and FID+SA lookups are performed. The FID+DA look up determines the forwarding ports. If FID+DA
fails, the packet will be broadcast to all the members (excluding the ingress port) of the VLAN. If FID+SA fails, the
FID+SA will be learned.
Examples:
1) VLAN Table Read (read the 3
rd entry)
Write to reg. 110 with 0x14 (read VLAN table selected)
Write to reg. 111 with 0x02 (trigger the read operation)
Then
Read reg. 118 (VLAN table bits 19-16)
Read reg. 119 (VLAN table bits 15-8)
Read reg. 120 (VLAN table bits 7-0)
2) VLAN Table Write (write the 7
th entry)
Write to reg. 118 (VLAN table bits 19-16)
Write to reg. 119 (VLAN table bits 15-8)
Write to reg. 120 (VLAN table bits 7-0)
Write to reg. 110 with 0x04 (write VLAN table selected)
Write to reg. 111 with 0x06 (trigger the write operation)
