Connectivity Guide

– -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. The default is 3.
– -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 species a number in milliseconds, otherwise it species 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 dierent 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.
