Revision 1.6
Static MAC Address Table
The KSZ8873 supports both a static and a dynamic MAC address table. In response to a destination address (DA) look
up, the KSZ8873 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 KSZ8873.
The static table is accessed by an external processor via the SMI, SPI or I
2C interfaces. The external processor performs
all addition, modification and deletion of static MAC table entries.
