Static MAC Address
KS8995MA/FQ has a static and a dynamic address table. When a DA look-up is requested, both tables will be searched
to make a packet forwarding decision. When an SA look-up is requested, only the dynamic table is searched for aging,
migration, and learning purposes. The static DA look-up result will have precedence over the dynamic DA look-up result. If
there are DA matches in both tables, the result from the static table will be used. The static table can only be accessed
and controlled by an external SPI master (usually a processor). The entries in the static table will not be aged out by
KS8995MA/FQ. An external device does all addition, modification and deletion. Note: Register bit assignments are
different for static MAC table reads and static MAC table write, as shown below:
Address

Format of Static MAC Table for Reads (8 entries)
60
57
FID
Filter VLAN ID, representing one of the 16 active VLANs
RO
0000

Use FID
1, use (FID+MAC) to look-up in static table.
0, use MAC only to look-up in static table.
RO
0
55
Reserved
Reserved.
RO
N/A
54
Override
1, override spanning tree “transmit enable = 0” or “receive
enable = 0* setting. This bit is used for spanning tree
implementation.
0, no override.

Forwarding Ports
The 5 bits control the forward ports, example:
00001, forward to port 1
00010, forward to port 2
…..
10000, forward to port 5
00110, forward to port 2 and port 3
11111, broadcasting (excluding the ingress port)

Use FID
1, use (FID+MAC) to look-up in static table.
0, use MAC only to look-up in static table.
W

Override
1, override spanning tree “transmit enable = 0” or “receive
enable = 0” setting. This bit is used for spanning tree
implementation.
0, no override.
