Description
Numeric identifier for the TPerf tunnel.
Priority High, Medium, or Low.
Number of bytes transmitted.
Number of bytes received.
Number of protocol data units transmitted.
Number of protocol data units received.
Number of bad CRC headers received.
Number of bad CRC payloads received.
Number of out-of-sequence PDUs received.
Flow control count.
The percentage of packet loss.
The number of bytes transmitted per second.
The time it took for the last round trip between the Tperf source and
the Tperf sink in milliseconds. This is calculated only on the source
side report. It is reported as N/A on the sink side report.
