Offset
0x1D
0x1E
0x1F
Example:
1. MIB Counter Read (read port 1 “Rx64Octets” counter at indirect address offset 0x0E)
In the heaviest condition, the byte counter will overflow in 2 minutes. It is recommended that the software read all
the counters at least every 30 seconds.
MIB counters are designed as “read clear”. That is, these counters will be cleared after they are read.
Counter Name
TxExcessiveCollision
TxSingleCollision
TxMultipleCollision
Then
Write to reg. IACR (0xC8) with 0x1C0E (set indirect address and trigger a read MIB counters operation)
Read reg. IADHR (MIB counter value 31-16)
Read reg. IADLR (MIB counter value 15-0)
Table 14. Port 1 MIB Counters Indirect Memory Offsets
Description
A count of frames for which Tx fails due to excessive collisions
Successfully Tx frames on a port for which Tx is inhibited by exactly one collision
Successfully Tx frames on a port for which Tx is inhibited by more than one collision
