Table 10. “All Port Dropped Packet” MIB Counters Format
Note: “All Port Dropped Packet” MIB Counters do not indicate overflow or validity; therefore, the application must keep track of overflow and
valid
conditions.
“All Port Dropped Packet” MIB counters are read using indirect memory access. The address offsets for these counters
are shown in Table 11.
