Static MAC Address
KS8995M 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 KS8995M. 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 in the two tables below.
Address
Name
Description
Mode
Default
Format of Static MAC Table for Reads (8 entries)
60-57
FID
Filter VLAN ID, representing one of the 16 active VLANs
RO
0000
56
Use FID
1, use (FID+MAC) to look-up in static table.
RO
0
0, use MAC only to look-up in static table.
55
Reserved
RO
N/A
54
Override
1, override spanning tree “transmit enable = 0” or
RO
0
“receive enable = 0” setting. This bit is used for
spanning tree implementation.
0, no override.
53
Valid
1, this entry is valid, the look-up result will be used
RO
0
0, this entry is not valid.
52-48
Forwarding ports
The 5 bits control the forward ports, example:
RO
00000
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)
47-0
MAC address
48 bit mac address
RO
0x0
Format of Static MAC Table for Writes (8 entries)
59-56
FID
Filter VLAN ID, representing one of the 16 active VLANs.
W
0000
55
Use FID
1, use (FID+MAC) to look-up in static table.
0, use MAC only to look-up in static table.
W
0
54
override
1, override spanning tree “transmit enable = 0” or
W
0
“receive enable = 0” setting. This bit is used for
spanning tree implementation.
0, no override.
53
valid
1, this entry is valid, the look-up result will be used.
