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

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
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.
The following arguments are optional when creating a data source switch. They do not apply to a
data sink switch.
-high
Generates high priority traffic.
-medium
Generates medium priority traffic.
-low
Generates low priority traffic.
NOTE
If no traffic priority is specified, high, medium, and low priority traffic is generated.
