Traceroute

This section describes the Traceroute feature.

Traceroute Overview

Use Traceroute to discover the routes that packets take when traveling on a hop-by-hop basis to their destination through the network.

zMaps network routes by sending packets with small Time-to-Live (TTL) values and watches the ICMP time-out announcements

zCommand displays all L3 devices

zCan be used to detect issues on the network

zTracks up to 20 hops

zDefault UPD port used 33343 unless modified in the traceroute command

NOTE: You can execute Traceroute with CLI commands only — there is no Web interface for this feature.

CLI Example

The following shows an example of using the traceroute command to determine how many hops there are to the destination.

The command output shows each IP address the packet passes through and how long it takes to get there. In this example, the packet takes 13 hops to reach its destination.

(Console)					#traceroute?
<ipaddr>					Enter IP address.
(Console)					#traceroute 216.109.118.74 ?
<cr>					Press Enter to execute the command.
<port>					Enter port no.
(Console)					#traceroute 216.109.118.74
