Use the Traceroute page in the J-Web interface to trace a route between the switch and
a remote host. You can use a traceroute task to display a list of waypoints between the
switch and a specified destination host. The output is useful for diagnosing a point of
failure in the path from the switch platform to the destination host and addressing network
traffic latency and throughput problems.

the traceroute operation are being displayed.
The switch generates the list of waypoints by sending a series of ICMP traceroute packets
in which the time-to-live (TTL) value in the messages sent to each successive waypoint
is incremented by 1. (The TTL value of the first traceroute packet is set to 1.) In this manner,
each waypoint along the path to the destination host replies with a Time Exceeded packet
from which the source IP address can be obtained.
The results of the traceroute operation are displayed in the main pane. If no options are
specified, each line of the traceroute display is in the following format:
hop-number host (ip-address) [as-number] time1 time2 time3
The switch sends a total of three traceroute packets to each waypoint along the path
and displays the round-trip time for each traceroute operation. If the switch times out
before receiving a Time Exceeded
time.
