Static MAC Address Table
The KSZ8993M has both a static and a dynamic MAC address table. When a destination address (DA) lookup is
requested, both tables are searched to make a packet forwarding decision. When a SA lookup is requested, only
the dynamic table is searched for aging, migration and learning purposes. The static DA lookup result will have
precedence over the dynamic DA lookup result. If there is a DA match in both tables, the result from the static
table will be used. The static table can be accessed and controlled by an external processor via the SMI, SPI and
I
2C interfaces. The external processor performs all addition, modification and deletion of static table entries.
These entries in the static table will not be aged out by the KSZ8993M.
