MIB (Management Information Base) Counters
The KSZ8841-PMQL provides 32 MIB counters to monitor the port activity for network management. The MIB counters
are formatted as shown in Table 4.

Table 4. Format of Port MIB Counters
The port MIB counters are read using indirect memory access. The base address offsets is 0x00 and address ranges is
0x00-0x1F as shown in Table 5.
The 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 4.
