Tracing Unicast Routes from the J-Web Interface

You can use the traceroute diagnostic tool to display a list of routers between the Services Router and a specified destination host. The output is useful for diagnosing a point of failure in the path from the Services Router to the destination host, and addressing network traffic latency and throughput problems.

The Services Router generates the list of routers by sending a series of ICMP traceroute packets in which the time-to-live (TTL) value in the messages sent to each successive router is incremented by 1. (The TTL value of the first traceroute packet is set to 1.) In this manner, each router along the path to the destination host replies with a Time Exceeded packet from which the source IP address can be obtained.

Alternatively, you can use the CLI traceroute command to generate the list.
