Zhone 5100 参照マニュアル

You can record the route (via specific gateway computers at each hop) through the Internet 

between your computer and a specified destination computer by issuing the traceroute 

command. This command also calculates and displays the amount of time each hop takes. 

Traceroute uses an ICMP packet stamped with the Time To Live value (TTL) designed to be 

exceeded by the first router that receives it, which will return a Time Exceeded message. However, 

if six consecutive time-outs occur to the same IP address, the utility considers that the end of the 

trace, stops, and prints a message. 
Syntax: traceroute <ip address or dnsname > [-d] [-h xx] [-w xxxx]
Arguments:

ip address or dnsname

the name of the DNS server or IP address

-d  

do not resolve the IP address to the host name

-h xxx 

maximum number of hops to search for host [0-255 (0 = use the default of 30)]

-w xxxx 

wait time in milliseconds for each reply [0-65535 (0 = use the default of 3000)]

Example:

In this example, the first hop away from the 5100/6100 VDR is 64.139.10.190, the second hop 

away from the 5100/6100 VDR is 172.16.0.1, and the third hop away is 71.45.3.5. After the third 

hop, the request timed out.
