Overflow
RO
1 = counter overflow.
0 = no counter overflow.
0
30
Count valid
RO
1 = counter value is valid.
0 = 0 counter value is not valid.
0
29-0
Counter values
RO
Counter value (read clear)
0x00000000
Table 11. Format of MIB Counters
Ethernet port MIB counters are read using indirect memory access. The address offset range is 0x00 to 0x1F.
