MIB (Management Information Base) Counters
The KSZ8842M provides 34 MIB counters for each port. These counters are used to monitor the port activity for network
management. The MIB counters are formatted “per port” as shown in Table 14 and “all ports dropped packet” as shown in
Table 16.

Table 14. Format of Per Port MIB Counters
“Per Port” MIB counters are read using indirect memory access. The base address offsets and address ranges for both
Ethernet ports are:
Port 1, base address is 0x00 and range is from 0x00 to 0x1f.
Port 2, base address is 0x20 and range is from 0x20 to 0x3f.
Per port MIB counters are read using indirect access control register in IACR, Bank 42 (0x00) and indirect access data
registers in IADR4[15:0], IADR5[31:16]. Table 15 shows the port 1 MIB counters address memory offset.
