UnsupportedMulticastCount This counter is incremented for each multicast packet received by
the board that is not registered with the driver.
BackToBackSendCount This counter is incremented each time the driver can buffer a
send packet onto the network board while the board is sending a
previous buffer.
Use this counter to track congestion on the network board.
See also EnqueuedSendsCount.
EnqueuedSendCount This counter is incremented when the driver is unable to transmit
a packet and must put the packet in a queue until the transmitter
is available.
Use the counter to track congestion on the network board.
See also BackToBackSendCount.
HeartBeatError
(NE2100
TM
, NE1500T
TM
, or CNEAMD
TM
) This counter is
incremented when there is a signal quality error.
This function is also known as the heartbeat or Signal Quality
Error (SQE) test.
This counter indicates a hardware problem.
MemoryTimeout (NE2100, NE1500T, or CNEAMD) This counter is incremented
when there is contention on the bus.
If this counter is incremented, there may be multiple boards in the
server or another bus-mastering device in the server, such as a
LAN or disk channel device.
TxBabblingError (NE2100, NE1500T, or CNEAMD)This counter is incremented
when there is excessive length in the transmit buffer.
It will increment after 1,519 data bytes have been transmitted
from the buffer.
It indicates that the transmitter has been on the channel longer
than the time required to send the maximum length packet.
If this counter is incremented, it indicates a hardware problem
with the network board in the server.
