Tx_ERF_Interface_Drop
A count of all Packets addressed to a interface that is not supported by the DAG
card.
Example:
When transmitting an existing capture file from a four interface DAG card to a
two interface DAG card, all packets for interface 2 and 3 are discarded.
Tx_ERF_RXError_Drop
A count of packets discarded with an RX_Error flag.
When the DAG card is configured in notxrxerror mode all packets marked
with an
RX_Error
flag are discarded.
Tx_ERF_MinLen_Drop
Tx_ERF_MaxLen_Drop
Packets in the transferred ERF stream what are either to short or to long are
discarded before they are released. The amount of discarded packets is shown
in the ERF_minLen and the ERF_MaxLen drop counter.
Example:
For Ethernet the allowed packet size is between 32 and 9616 bytes.
Tx_IF_Late_Release
When operating in Time-Release mode each packet is transmitted according to
its timestamp. When consecutive packets shall be released at the same time
they have the same timestamp. However, because of the sequential nature of
the stream the second packet is send out after the first packet. This "late"
release is noted by the DAG card and each event increments the late release
counter.
