-N squeries (Optional) Enter the number of probe packets sent out simultaneously to
accelerate traceroute. The default is 16.
-t tos (Optional) For IPv4, enter the type of service (ToS) and precedence values to use. 16
sets a low delay; 8 sets a high throughput.
-UL (Optional) Use UDPLITE for tracerouting. The default port is 53.
-w waittime (Optional) Enter the time in seconds to wait for a response to a probe. The
default is 5 seconds.
-z sendwait (Optional) Enter the minimal time interval to wait between probes. The default
is 0. A value greater than 10 specifies a number in milliseconds, otherwise it specifies a number of
seconds. This option is useful when routers rate-limit ICMP messages.
--mtu (Optional) Discovers the maximum transmission unit (MTU) from the path being traced.
--back (Optional) Prints the number of backward hops when different from the forward
direction.
host (Required) Enter the name or IP address of the destination device.
packet_len (Optional) Enter the total size of the probing packet. The default is 60 bytes for
IPv4 and 80 for IPv6.
