Static MAC Address Table
The KSZ8842-PMQL/PMBL supports both a static and a dynamic MAC address table. In response to a Destination
Address (DA) look up, The KSZ8842-PMQL/PMBL 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. These entries in the static table will not be aged out by the KSZ8842-
PMQL/PMBL.

1 = overrides the port setting “transmit enable=0” or “receive enable=0”
setting.
0 = specifies no override

Forwarding ports
These 3 bits control the forwarding port(s):
000 ,no forward
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)

MAC address
48 bits MAC Address
Table 12. Static MAC Table Format (8 Entries)
Examples:
1. Static Address Table Read (read the second entry at indirect address offset 0x01)
Write to reg. IACR with 0x1001 (set indirect address and trigger a read static MAC table operation)
Then
Read reg. IADR3 (static MAC table bits 57-48)
Read reg. IADR2 (static MAC table bits 47-32)
Read reg. IADR5 (static MAC table bits 31-16)
Read reg. IADR4 (static MAC table bits 15-0)
2. Static Address Table Write (write the eighth entry at indirect address offset 0x07)
Write to reg. IADR3 (static MAC table bits 57-48)
Write to reg. IADR2 (static MAC table bits 47-32)
Write to reg. IADR5 (static MAC table bits 31-16)
Write to reg. IADR4 (static MAC table bits 15-0)
Write to reg. IACR with 0x0007 (set indirect address and trigger a write static MAC table operation)
