Description: Contains the number of Drop 512 byte buffers.
What is hwBuffer512DropCounts?
This counter accumulates the number of packets discarded due to 512-byte buffer exhaustion since last reboot. Rising drop counts indicate insufficient buffer allocation or sustained network overload. If the counter increments from 1000 to 1050 over an hour, packets are being lost during traffic spikes.
Examples
