Description Use this command to invoke the end-to-end IP path performance (ipperf) characterization feature,
to ping or trace a route to a destination IP host from an intelligent GbE port, or to determine the
path characteristics between a local data source and a remote data sink.
When issued with the --tperf option, this command determines the path characteristics to a
remote host or tunnel destination. TPerf generates statistics every 30 seconds by default unless
you specify a different value for -interval. The output displays the following information:
Tunnel ID Numeric identifier for the TPerf tunnel.
Traffic Priority High, Medium, or Low.
bytes tx Number of bytes transmitted.
bytes rx Number of bytes received.
PDUs tx Number of protocol data units transmitted.
PDUs rx Number of protocol data units received.
bad CRC headers rx Number of bad CRC headers received.
bad CRC payloads rx Number of bad CRC payloads received.
out of seq PDUs rx Number of out-of-sequence PDUs received.
flow control count Flow control count.
last rtt Last Round trip in milliseconds (RT traffic only).
When issued with the ipperf option, this command determines characteristics of the path to the
remote host. The output of --ipperf -S includes the following information:
Sampling frequency(s)
The interval specified with the -i option or the default (30 seconds).
Total Time(s) The time in seconds the command has been running since it was last issued.
BW The bandwidth measured in the last interval. Bandwidth is defined as the
total number of transmitted packets in bytes. BW represents what the FCIP
tunnel and the FC application register as throughput rather than the Ethernet
on-the-wire bytes.
WBW The current bandwidth weighted with a gain of 50%.
