Parameters Meaning
Packet DMA counters
Receive
Counters for packets received.
Packets The number of packets received by the CPU from the switch chip.
Discards The number of packets received from the switch chip that were
discarded because either the receive queue was greater than
4096, or because the free buffers in the switch were below
BufferLevel3, or because there were no data bytes in the packet.
TooFewBuffers The number of packets received from the switch chip that were
discarded because the free buffers in the switch were below
BufferLevel3.
DescriptorsExhausteds The number of times the switch chip reported that it could not
transfer a packet by DMA to a switch buffer because there were
no more receive buffer descriptors.
QueueLength The number of packets received from the switch chip waiting to
be processed by the CPU.
Trans mi t
Counters for packets transmitted.
Packets The number of packets transferred from the CPU to the switch
chip.
