10.7.4.6 Buffer Manager Port 0 Drop Count Register (BM_DRP_CNT_SRC_0)
Register #:
1C05h
Size:
32 bits
This register counts the number of packets dropped by the Buffer Manager that were received on Port 0. This count
includes packets dropped due to buffer space limits and ingress rate limit discarding (Red and random Yellow dropping).
Bits
Description
31:0 Dropped Count
These bits count the number of dropped packets received on Port 0 and is
cleared when read.
Note: The counter will stop at its maximum value of FFFF_FFFFh.
Minimum rollover time at 100 Mbps is approximately 481 hours.
Type
RC
