JunosE 11.3.x IP, IPv6, and IGP Configuration Guide

Use the source interface keywords to specify a source interface other than the one
from which the probe originates.
Use the source address keywords to specify a source IP address other than the one
from which the probe originates.
You can specify the following options:
packetCount—Number of packets to send to the destination IP address. If you specify
a zero (0), echo requests packets are sent indefinitely.
data-pattern—Sets the type of bits contained in the packet to all ones, all zeros, a
random mixture of ones and zeros, or a specific hexadecimal data pattern that can
range from 0x0–0xFFFFFFFF. The default is all zeros.
data-size—Sets the number of bytes comprising the IP packet and reflected in the
IP header in the range 0–64000; the default is 100 bytes.
extended header attributes—Set the following:
A value to be set in the type of service (ToS) byte, in the range 0–255, to support
quality of service (QoS) offerings
Don't-fragment bit to prevent IP from fragmenting the packet if it is too long for
the MTU of a given link; if the nonfragmented packet cannot be delivered, it is
discarded.
Strict-source or loose-source routing, including the IP address of the hops the
packets must traverse. For loose-source-route, you specify some or all of the hops,
but they do not have to be adjacent. For strict-source-route, you must specify
every adjacent hop through which the packet must traverse.
The IP addresses to be recorded for a specified number of routers that the packets
traverse.
The time that a packet traverses a router to be recorded for a specified number
of routers.
An interface type and specifier of a destination address on the router that is
connected for external loopback by means of a cable or plug that loops Tx to Rx.
The command succeeds only if the specified interface is connected for external
loopback and the encapsulation type is ATM, Frame Relay, HDLC, or PPP. The
command does not work for Ethernet or VLAN encapsulations.
The traffic class value to match in the Traffic Class field of each packet (IPv6 only)
The flow label value to match in the Flow Label field of each packet (IPv6 only)
sweep-interval—Specifies the change in the size of subsequent ping packets while
sweeping across a range of sizes. For example, you can configure the sweep interval
to sweep across the range of packets from 100 bytes to 1000 bytes in increments
equal to the sweep interval. By default the router increments packets by one byte;
for example, it sends 100, 101, 102, 103, ... 1000. If the sweep interval is 5, the router
sends 100, 105, 110, 115, ... 1000.
