The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may
be in place. Refer to chapter 1, "Using Fabric OS commands" and Appendix A, "Command
Availability" for details.
Operands This command has the following operands:
slot For bladed systems only, specify the slot number of the port to be configured,
followed by a slash (/).
ge port Specifies the port number of the GbE port on the blade.
--ipperf Determines the path characteristics to the remote host. Valid arguments and
their values include the following:
-s src_ip Specifies the local IP address to use for sourcing the probe packets. ipperf
will not start if there exists an IPSec-enabled tunnel using the same source IP
address.
-d dst_ip Specifies the destination IP address to which to probe the IP router path.
-S Instructs the source mode to initiate the TCP connection. The source
end-point generates a traffic stream and reports the end-to-end IP path
characteristics from this end-point to the receiver end-point sink.
-R Instructs the sink mode to accept the new connection. The end-to-end path
characteristics are not reported.
-i interval Specifies the intervals between polling and displaying statistics, in seconds. If
the duration is less than -t running_time, the statistics displays only once, at
the conclusion of the test. This operand is optional.
-p port Specifies the TCP port number for the listener end-point. This operand is
optional.
-q diffserv Specifies the DSCP (DiffServ Code Point) marking used for the TCP
connection. This operand accepts values between 0 and 63. The default
value is 0. This operand is optional.
-r committed_rate
Specifies a committed rate for the data stream, in Kbps. If specified, the
traffic generator is limited by a traffic shaper. This characterizes the
end-to-end IP path performance based on the data rate configured for a
tunnel between the same end-points. If a rate is not specified, the traffic
generator competes for uncommitted bandwidth. This operand is optional.
-t running_time Specifies total time to run the test traffic stream, in seconds. If not specified,
the test runs continuously until aborted with Ctrl+c. This operand is optional.
-z size Specifies the size, in bytes, of the trace route packet to use. The default is 64
bytes. In an IPv4 environment, the ICMP/IP header occupies 28 bytes. In an
IPv6 environment, it occupies 48 bytes. The total size, including ICMP/IP
headers (28 or 48 bytes without IP options) cannot be greater than the IP
MTU configured on the interface. This operand is optional.
-v vlan_id Specifies 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 is dynamically
maintained by the ipperf application. See the portCfg help page for details on
creating a VLAN tag table.
