Information on the Ethernet Statistics menu
Status Bits
Ether Address The logic analyzer’s Ethernet address. This value is set by the factory
and cannot be changed.
Subnet Mask 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.
Trans mit
Successful Number of successfully transmitted packets.
Not
successful
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.
Deferred Number of packets deferred due to network traffic. After 15 deferrals,
the not successful field is incremented.
Collisions Number of packets that had to be retransmitted due to network
traffic.
Late collisions Number of illegal collisions that have occurred after 51.2 ms from
either the first bit of preamble or from SFD (Start of Frame Delimiter).
No heartbeat Number of packets where the transceiver fails to provide a collision
pulse.
Receive
Successful Number of successfully received packets.
Missed
packets
Number of packets that were dropped for lack of resources in the
logic analyzer.
Bad CRC Number of corrupt packets.
Frame align
error
Number of packets with frame alignment error.
