Write to reg. 110 with 0x1d (read MIB counter selected)
Write to reg. 111 with 0x00 (trigger the read operation)
Then
Read reg. 119 (counter value 15-8)
Read reg. 120 (counter value 7-0)
NOTES:
1.
Both “Per Port” and “All Port Dropped Packet” MIB Counters do not indicate overflow. The application must
keep track of overflow conditions for these counters.
2.
“All Port Dropped Packet” MIB Counters do not indicate if count is valid. The application must keep track of
valid conditions for these counters.
3.
To read out all the counters, the best performance over the SPI bus is (160+3)*8*200 = 260 ms, where there
are 160 registers, 3 overheads, 8 clocks per access, at 5 MHz. In the heaviest condition, the counters will
overflow in 2 minutes. It is recommended that the software read all the counters at least every 30 seconds.
4.
A high performance SPI master is recommended to prevent counters overflow.
5.
“Per Port” MIB Counters are designed as “read clear”. These counters will be cleared after they are read.
6.
“All Port Dropped Packet” MIB counters are not cleared after they are read.
