“Per Port” MIB Counters are read using indirect memory access. The base address offsets and address ranges for all
three ports are:
Port 1’s “Per Port” MIB Counters Indirect Memory Offsets are shown in the following table:
August 26, 2004
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)

Description
Rx lo-priority (default) octet count including bad packets
Rx hi-priority octet count including bad packets
Rx undersize packets w/ good CRC
Rx fragment packets w/ bad CRC, symbol errors or alignment
errors
Rx oversize packets w/ good CRC (max: 1536 or 1522 bytes)
Rx packets longer than 1522 bytes w/ either CRC errors,
Alignment errors, or symbol errors. (Depends on max packet
size setting).
Rx packets w/ invalid data symbol and legal packet size.
Rx packets within (64,1522) bytes w/ an integral number of
bytes and a bad CRC (Upper limit depends on max packet
size setting).
Rx packets within (64,1522) bytes w/ a non-integral number of
bytes and a bad CRC (Upper limit depends on max packet
size setting).
