Static MAC Address Table
The KSZ8863 supports both a static and a dynamic MAC address table. In response to a Destination Address (DA) look
up, the KSZ8863 searches both tables to make a packet forwarding decision. In response to a Source Address (SA) look
up, only the dynamic table is searched for aging, migration and learning purposes.
The static DA look up result takes precedence over the dynamic DA look up result. If there is a DA match in both tables,
the result from the static table is used. The entries in the static table will not be aged out by the KSZ8863.
The static table is accessed by a external processor via the SMI, SPI or I2C interfaces. The external processor performs
all addition, modification and deletion of static MAC table entries.

= 0, use MAC only for static table look ups

“receive enable=0” setting
= 0, no override

These 3 bits control the forwarding port(s):
48-bit MAC Address
// Read static table selected
// Trigger the read operation
001, forward to port 1
010, forward to port 2
100, forward to port 3
011, forward to port 1 and port 2
110, forward to port 2 and port 3
101, forward to port 1 and port 3
111, broadcasting (excluding the
ingress port)
