The previous display shows VE_Port 16 as up, but a switchshow command for that same VE _Port
will show the following:
switch:admin> switchshow | grep 16

The Tperf command determines the path characteristics to a remote host or tunnel destination.
The syntax is as follows:
portcmd - -tperf slot/VE_port number -sink -source -high | -medium | -low -time duration]
-unidirectional -random -pattern pattern -size pdu_size -interval interval
For full details on syntax and using this command, refer to the Fabric OS Command Reference
Manual.
The following examples create a Tperf data sink and a Tperf data source on VE_Port 16.
switch:admin> portcmd --tperf 16 -sink -interval 15
switch:admin> portcmd --tperf 16 -source -interval 15 -high -medium -low
For details on this command, syntax, and output examples, refer to the Fabric OS Command
Reference Manual.
Tperf generates statistics every 30 seconds by default unless you specify a different value for
-interval.

Tperf output
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.
