Tperf will test single and multiple circuit tunnels. Tperf also tests the different priority connections
that are provided by an FCIP Tunnel. When a Tperf--enabled tunnel is operative, it is not an active
VE port. Fabrics will not merge over an operative FCIP Tperf tunnel. To determine if the Tperf tunnel
is up, issue the following command:
switch:admin> portshow fciptunnel all -c

Flags: tunnel: c=compression f=fastwrite t=Tapepipelining F=FICON T=TPerf
The above 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> <required arguments> <optional arguments>
The following arguments are required.
-sink | -source
The following arguments are optional when creating a data source switch. They do not apply to a
data sink switch.
-high
-medium
-low

Designates the switch to function either as a data sink or a data source.
When -sink is specified, the -high, -medium, -low, -unidirectional, -random,
-pattern, and -size options are not used. The switch acting as the sink
responds to traffic from the switch acting as the data source, and does not
shape the traffic.
When -source is specified, Tperf generates traffic to be sent to the switch
acting as the data sink. The -high, -medium, -low, -unidirectional, -random,
-pattern, and -size options can be used to shape the traffic.
The tperf module on the data source switch immediately begins generating
traffic, so Tperf module on the data sink switch must be started before Tperf
is started on the source switch.
Generates high priority traffic.
Generates medium priority traffic.
Generates low priority traffic.
NOTE
If no traffic priority is specified, high, medium, and low priority traffic is generated.
