OPERANDS
This command has the following operands:
slot
ge port
--ipperf
Fabric OS Command Reference
53-1001764-01
For bladed systems only, specifies the slot number of the port to be configured,
followed by a slash (/).
Specifies the port number of the GbE port on the blade.
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. The ipperf
command will not start, if an IPSec-enabled tunnel exists that uses the same
source IP address. IPv6 addresses are supported.
-d dst_ip
Specifies the destination IP address to which to probe the IP router path. IPv6
addresses are supported.
-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 greater 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.
