Table 34 Advanced traceRoute options
Option Description
ttl Determines the maximum number of hops that the system
can use in outgoing probe packets.
port The destination (or base) UDP port number that the system
uses in probe packets. Set the destination UDP port
number to a very high value to make sure that an
application at the destination is not using that port. The
valid port numbers are numbers greater than 30,000 which
makes it unlikely that an application would be using this
port.
probeCount The maximum number of probes that the system sends out
at each TTL level.
wait The wait interval determines the maximum amount of
time, in seconds, that the module waits for a response to a
probe. Valid values are 1 through 10.
packetSize The number of bytes in each UDP probe packet. Valid
packet sizes are 28 through 4096.
