traceroute <host>
Displays the route packets take to a network host.
Syntax
traceroute [ipv4 | ipv6] host
Command Mode
Operational mode
Parameters
ipv4 |
Display the route packets take to the host’s IPv4 address. This |
|
option is to be used when the host specified is a hostname rather |
|
than an IP address. |
|
|
ipv6 |
Display the route packets take to the host’s IPv6 address. This |
|
option is to be used when the host specified is a hostname rather |
|
than an IP address. |
|
|
host |
The host that is the destination for the trace. Can be specified |
|
either as a name (if DNS is being used on the network) or as an |
|
IPv4 or IPv6 address. |
|
|
Usage Guidelines
Use this command to perform a “traceroute” operation for a network host. Traceroute utilizes the IP protocol time to live (“ttl”) field and attempts to elicit an ICMP TIME_EXCEEDED response from each gateway along the path to some host to track the route a set of packets follows. It attempts to trace the route an IP packet would follow to some Internet host by launching UDP probe packets with a small time to live, then listening for an ICMP “Time exceeded” reply from a gateway.
