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

00001, forward to port 1
00010, forward to port 2
…..
10000, forward to port 5
00110, forward to port 2 and port 3
