JunosE 11.3.x Command Reference Guide N to Z
190
source interface—Specifies an interface as the source of the packets
interfaceType—Interface type; see Interface Types and Specifiers on page 5
interfaceSpecifier—Particular interface; format varies according to interface type;
see Interface Types and Specifiers on page 5
source address—Specifies an IP address as the source of the packets
sourceAddr—IP address or domain name used as the source address
sweep-sizes—Configures payload sizes, enabling you to vary the sizes of the echo
packets being sent. This capability is useful for determining the minimum sizes of the
MTUs configured on the nodes along the path to the destination address. This reduces
packet fragmentation which contributes to performance problems. The default is not
to sweep (all packets are the same size).
sweepMin—Minimum payload size in the range 0–64000
sweepMax—Maximum payload size in the range 0–64000
sweepInt—Number of bytes to add to the size of the packet; 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 of sweepInt. By default, send 100, 101, 102,
103...1000. If sweepInt is 5, send 100, 105, 110, 115...1000). When " sweeping," the
default interval is 1.
extended—Enables you to configure extended header attributes
tosVal—Specifies the value set in the ToS byte in the range 0–255 to support QoS
offerings
set-dont-fragment-bit—Sets the don't-fragment bit in the IP header to prevent IP
from fragmenting the packet if it is too long for the MTU of a link; if the nonfragmented
packet cannot be delivered, it is discarded
set-router-alert—Sets the router alert bit in the IP header to indicate that all routers
should examine this packet more closely to determine whether further processing
is necessary
loose-source-route—Specifies a set of hops through which the packet must traverse;
the hops do not have to be adjacent
strict-source-route—Specifies every hop through which the packet must traverse
and generates an ICMP error if the exact path cannot be followed
srtAddrs—IP addresses or domain name of the intermediate hops on the way to the
destination to be used in the loose-source or strict-source route
*—Indicates that one or more parameters can be repeated multiple times in a list in
the command line
numRoutes—Specifies how many routes are to be recorded as the packet travels, in
the range 1–9
