Management Information Base (MIB) Counters
The KSZ8873 provides 34 MIB counters per port. These counters are used to monitor the port activity for network
management. The MIB counters have two format groups: “Per Port” and “All Port Dropped Packet.”

“Per Port” MIB counters are read using indirect memory access. The base address offsets and address ranges for all
three ports are:
Port 1, base is 0x00 and range is (0x00-0x1f)
Port 2, base is 0x20 and range is (0x20-0x3f)
Port 3, base is 0x40 and range is (0x40-0x5f)
Port 1 MIB counters are read using the indirect memory offsets in Table 20.
