Reference Guide

● host — Enter the host to trace packets from.
● -i interface — (Optional) Enter the IP address of the interface through which traceroute sends
packets. By default, the interface is selected according to the routing table.
● -m max_ttl — (Optional) Enter the maximum number of hops (maximum time-to-live value) that
traceroute probes (default 30).
● -p port — (Optional) Enter a destination port:
○ For UDP tracing, enter the destination port base that traceroute uses (the destination port number
is incremented by each probe).
○ For ICMP tracing, enter the initial ICMP sequence value (incremented by each probe).
○ For TCP tracing, enter the (constant) destination port to connect.
○
-P protocol — (Optional) Use a raw packet of the specified protocol for traceroute. Default
protocol is 253 (RFC 3692).
○ -s source_address — (Optional) Enter an alternative source address of one of the interfaces.
By default, the address of the outgoing interface is used.
○ -q nqueries — (Optional) Enter the number of probe packets per hop (default 3).
○ -N squeries — (Optional) Enter the number of probe packets that are sent out simultaneously
to accelerate traceroute (default 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 (default port is 53).
○ -w waittime — (Optional) Enter the time (in seconds) to wait for a response to a probe
(default 5 seconds).
○ -z sendwait — (Optional) Enter the minimal time interval to wait between probes (default
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 MTU from the path being traced.
○ --back — (Optional) Prints the number of backward hops when it seems different with 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 (default 60 bytes for IPv4
and 80 for IPv6).
