Traceroute

This section describes the traceroute feature. Use traceroute to discover routes that packets
take when traveling on a hop-by-hop basis to their destination through the network.
• Traceroute maps network routes by sending packets with small time-to-live (TTL) values
and watches the ICMP time-out announcements.
• The traceroute command displays all L3 devices.
• It can be used to detect issues on the network.
• Traceroute tracks up to 20 hops.
• The default UPD port is used 33343 unless you specify otherwise in the traceroute
command.
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 that the
packet passes through and how long it takes for the packet to reach its destination. In this
example, the packet takes 16 hops to reach its destination.
