■
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
■
numTstamps —Specifies how many timestamps from routers are to be
recorded as the packet travels, in the range 1–9
