Dynamic MAC Address Table
The KSZ8873 maintains the dynamic MAC address table. Read access is allowed only.
Table 18. Format of Dynamic MAC Address Table (1K Entries)
Bit
Name
R/W
Description
Default
71
Data Not
Ready
RO
= 1, entry is not ready, continue retrying until this
bit is set to 0
= 0, entry is ready
70-67
Reserved
RO
Reserved
66
MAC Empty
RO
= 1, there is no valid entry in the table
= 0, there are valid entries in the table
1
65-56
No of Valid
Entries
RO
Indicates how many valid entries in the table
0x3ff means 1K entries
0x001 means 2 entries
0x000 and bit 66 = 0 means 1 entry
0x000 and bit 66 = 1 means 0 entry
00_0000_0000
55-54
Time Stamp
RO
2 bits counter for internal aging
53-52
Source Port
RO
The source port where FID+MAC is learned
00 : port 1
01 : port 2
10 : port 3
00
51-48
FID
RO
Filter ID
0x0
47-0
MAC Address
RO
48-bit MAC Address
0x0000_0000_0000
Example:
1.
Dynamic MAC Address Table Read (Read the 1
st Entry and Retrieve the MAC Table Size)
Write to reg. 121 (0x79) with 0x18
// Read dynamic table selected
Write to reg. 122 (0x7A) with 0x00
// Trigger the read operation
Then,
Read reg. 123 (0x7B), bit [7]
// if bit 7 = 1, restart (reread)
from this register dynamic table bits [66:64]
Read reg. 124 (0x7C), dynamic table bits [63:56]
Read reg. 125 (0x7D), dynamic table bits [55:48]
Read reg. 126 (0x7E), dynamic table bits [47:40]
Read reg. 127 (0x7F), dynamic table bits [39:32]
Read reg. 128 (0x80), dynamic table bits [31:24]
Read reg. 129 (0x81), dynamic table bits [23:16]
Read reg. 130 (0x82), dynamic table bits [15:8]
Read reg. 131 (0x83), dynamic table bits [7:0]
