The logic analyzer's Ethernet address. This value is set by the
factory and cannot be changed.
The subnet mask being used by the logic analyzer. The logic
analyzer queries the network for this value when it is turned
on. The value cannot be changed.
Number of successfully transmitted packets.
Number of packets not transmitted due to errors. The
transmit not successful field is tied primarily to transmit
deferrals and possible hardware problems. If a packet is
deferred (not because of a collision), then the packet is given
a delay and retransmission is attempted. After 15 deferrals,
the not successful field is incremented.
Number of packets deferred due to network traffic. After 15
deferrals, the not successful field is incremented.
Number of packets that had to be retransmitted due to
network traffic.
Number of illegal collisions that have occurred after 51.2 µs
from either the first bit of preamble or from SFD (Start of
Frame Delimiter).
Number of packets where the transceiver fails to provide a
collision pulse.
Number of successfully received packets.
Number of packets that were dropped for lack of resources in
the logic analyzer.
Number of corrupt packets.
Number of packets with frame alignment error.
