Table 10: Format of Static MAC Table (8 entries)
Bit
Name
R/W
Description
Default
57-54
FID
R/W
Filter VLAN ID, representing one of the 16
active VLANs
0000
53
Use FID
R/W
= 1, use (FID+MAC) to look up in static
table
= 0, use MAC only to look up in static table
0
52
Override
R/W
= 1, override port setting “transmit
enable=0”
or “receive enable=0”
setting.
= 0, no override
0
51
Valid
R/W
= 1, this entry is valid, the look up result will
be used
= 0, this entry is not valid
0
50-48
Forwarding
ports
R/W
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)
000
47-0
MAC address
R/W
48 bits MAC Address
0x0000_0000_000
0
Examples:
1) Static Address Table Read (read the 2
nd entry)
Write to reg. 110 with 0x10 (read static table selected)
Write to reg. 111 with 0x01 (trigger the read operation)
Then
Read reg. 113 (57-56)
Read reg. 114 (55-48)
Read reg. 115 (47-40)
Read reg. 116 (39-32)
Read reg. 117 (31-24)
Read reg. 118 (23-16)
Read reg. 119 (15-8)
Read reg. 120 (7-0)
2) Static Address Table Write (write the 8
th entry)
Write reg. 113 (57-56)
Write reg. 114 (55-48)
Write reg. 115 (47-40)
Write reg. 116 (39-32)
Write reg. 117 (31-24)
Write reg. 118 (23-16)
Write reg. 119 (15-8)
Write reg. 120 (7-0)
Write to reg. 110 with 0x00 (write static table selected)
Write to reg. 111 with 0x07 (trigger the write operation)
