KSZ8895MQ/RQ/FMQ
Static MAC Address Table
KSZ8895MQ/RQ/FMQ 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 KSZ8895MQ/RQ/FMQ. 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 Table 15.
