Static MAC Address Table
The KSZ8893FQL supports both a static and a dynamic MAC address table. In response to a Destination Address (DA)
look-up, the KSZ8893FQL 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,
then the result from the static table is used. The entries in the static table will not be aged out by the KSZ8893FQL.
The static table is accessed by an external processor via the SMI, SPI or I
performs all addition, modification and deletion of static MAC table entries.

Description
Filter VLAN ID – identifies one of the 16 active VLANs
1 = Use (FID+MAC) for static table look ups
0 = Use MAC only for static table look ups
1 = Override port setting “transmit enable=0” or
“receive enable=0” setting
0 = No override
1 = This entry is valid, the lookup result will be used
0 = This entry is not valid
These 3 bits control the forwarding port(s):
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)
