Examples:
1. MIB Counter Read (read port 1 “Rx64Octets” counter at indirect address offset 0x0E)
Write to reg. IACR with 0x1c0e (set indirect address and trigger a read MIB counters operation)
Then
Read reg. IADR5 (MIB counter value 31-16) // If bit 31 =1, there was a counter overflow
// If bit 30 =0, restart (reread) from this register
Read reg. IADR4 (MIB counter value 15-0)
2. MIB Counter Read (read port 2 “Rx64Octets” counter at indirect address offset 0x2E)
Write to reg. IACR with 0x1c2e (set indirect address and trigger a read MIB counters operation)
Then
Read reg. IADR5 (MIB counter value 31-16) // If bit 31 =1, there was a counter overflow
// If bit 30 =0, restart (reread) from this register
Read reg. IADR4 (MIB counter value 15-0)
3. MIB Counter Read (read “Port1 TX Drop Packets” counter at indirect address offset 0x100)
Write to reg. IACR with 0x1d00 (set indirect address and trigger a read MIB counters operation)
Then
Read reg. IADR4 (MIB counter value 15-0)
Additional MIB Information
Per Port MIB counters are designed as “read clear”. That is, these counters will be cleared after they are read.
All Port Dropped Packet MIB counters are not cleared after they are accessed. The application needs to keep track of
overflow and valid conditions on these counters.
