VLAN Table
The KSZ8893FQL uses the VLAN table to perform look-ups. 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 in the following table.
Bit

Description
Default

R/W
1 = Entry is valid
0 = Entry is invalid
1
18-16
Membership
R/W
Specify which ports are members of the VLAN. If a DA lookup
fails (no match in both static and dynamic tables), the packet
associated with this VLAN will be forwarded to ports specified
in this field. For example, 101 means port 3 and 1 are in this
VLAN.
111
15-12
FID
R/W
Filter ID. KSZ8893FQL 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.

Table 22. Format of Static VLAN Table (16 Entries)
If 802.1Q VLAN mode is enabled, then the KSZ8893FQL 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 look-ups 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 fail,
the FID+SA will be learned.
Examples:
1. VLAN Table Read (read the 3
rd entry)
Write to reg. 121 (0x79) with 0x14
// Read VLAN table selected
Write to reg. 122 (0x7A) with 0x02
// Trigger the read operation
Then,
Read reg. 129 (0x81), VLAN table bits [19:16]
Read reg. 130 (0x82), VLAN table bits [15:8]
Read reg. 131 (0x83), VLAN table bits [7:0]
2. VLAN Table Write (write the 7
th entry)
Write to reg. 129 (0x81), VLAN table bits [19:16]
Write to reg. 130 (0x82), VLAN table bits [15:8]
Write to reg. 131 (0x83), VLAN table bits [7:0]
Write to reg. 121 (0x79) with 0x04
// Write VLAN table selected
Write to reg. 122 (0x7A) with 0x06
// Trigger the write operation
