MIB (Management Information Base) Counters
The KSZ8842-PMQL/PMBL provides 32 MIB counters for port 1, port 2, and the host port. These counters are used to
monitor the port activity for network management. The MIB counters are formatted “per port” as shown in Table 8, and
“per all port dropped packet” as shown in Table 8.

Table 8. 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 of the MIB counter is 0x00 and range is (0x00-0x1f) as shown in Table 9.
Port 2, base address of the MIB counter is 0x20 and range is (0x20-0x3f) as refer in Table 9.
Host port, base address of the MIB counter is 0x40 and range is (0x40-0x5f) as refer in Table 9.
Per Port MIB counters read/write functions use Access Control register IACR (0x04A0) bit 12. The base address offset
and address range for port 1 is 0x00 and range is (0x00-0x1F) that can be changed in register IACR (0x04A0) bits[9:0].
The data of MIB counters are from the Indirect Access data register IADR4 (0x04A8) and IADR5 (0x04AA) based on
Table 9.
