Ipperf options

Please refer to Brocade Fabric OS Command Reference Manual or the man pages for definitive
command syntax and option descriptions. Ipperf options are repeated here for convenience.

ipperf [slot]/ge0|ge1 -s source_ip -d destination_ip -S|-R [-r rate] [-z size] [-t time]
--
The source IP address.
The destination IP address.
Operates the WAN tool FCIP port-embedded client in the sender mode. The
test endpoint will generate a traffic stream and report the end-to-end IP path
characteristics from this endpoint toward the receiver endpoint. This option
cannot be used with the –R option.
Operates the WAN tool FCIP-port embedded client in the receiver mode. The
test endpoint will accept a connection and traffic stream from the sender This
option cannot be used with the -S option.
The committed rate for the data stream in Kb/s. If specified, the traffic
generator will be limited by a traffic shaper. This can be used to characterize
the end-to-end IP path performance based on the data rate to be configured
for a tunnel between the same endpoints. If a rate is not specified then the
traffic generator will compete for uncommitted bandwidth.
The size in bytes for each buffer handed to the TCP layer. If a size is not
specified, the maximum size data buffer will be used based on the outbound
IP interface MTU. The size is the only buffer size that will be handed over to
the TCP layer.
The total time in seconds to run the test traffic stream. If a time is not
specified, the test will run continuously until stopped by typing ctrl-C.
The interval in seconds between polling and printing stats. The default is 30
sec. If this time is greater than the running time (specified by –t), the stats will
be printed only once at the conclusion of the test.
The TCP port number for the listener endpoint. If a TCP port is not specified,
port 3227 is used (this is next port after ports 3225 and 3226, which are
used for the FCIP tunnel connections).
The DiffServ marking code point (DSCP) for the TCP connection. The value
must be an integer in the range of 0 to 63. The default value is 0. This
operand is optional. Before configuring DSCP settings, determine if the IP
network you are using implements PHB, and consult with the network
administrator to determine the appropriate DSCP values.
The VLAN ID. Values must be in the range of 1 - 4094. There is no default
value. Note that a VLAN tag entry must exist on the local and remote sides
prior to issuing the -v option. A VLAN Tag table entry will be dynamically
maintained by the ipperf application.
The Class of Service/Priority as defined by IEEE 802.1p. Values must be in
the range between 0 and 7. The default is 0. This operand is optional with the
-v option
