Using the J-Web Traceroute Tool

To use the traceroute tool:

  1. Select Diagnose>Traceroute.
  2. Next to Advanced options, click the expand icon (see Figure 113).
  3. Enter information into the Traceroute page, as described in Table 177.

    The Remote Host field is the only required field.

  4. Click Start.

    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 device sends a total of three traceroute packets to each router along the path and displays the round-trip time for each traceroute operation. If the device times out before receiving a Time Exceeded message, an asterisk (*) is displayed for that round-trip time.

    Table 178 summarizes the output fields of the display.

  5. To stop the traceroute operation before it is complete, click OK while the results of the traceroute operation are being displayed.

Your Action

Remote Host

Identifies the destination host of the traceroute.

Type the hostname or IP address of the destination host.

Advanced Options

Don't Resolve Addresses

Determines whether hostnames of the hops along the path are displayed, in addition to IP addresses.

  • To suppress the display of the hop hostnames, select the check box.
  • To display the hop hostnames, clear the check box.


Specifies the IP address of the gateway to route through.

Type the gateway IP address.

Source Address

Specifies the source address of the outgoing traceroute packets.

Type the source IP address.

Bypass Routing

Determines whether traceroute packets are routed by means of the routing table.

If the routing table is not used, traceroute packets are sent only to hosts on the interface specified in the Interface box. If the host is not on that interface, traceroute responses are not sent.

  • To bypass the routing table and send the traceroute packets to hosts on the specified interface only, select the check box.
  • To route the traceroute packets by means of the routing table, clear the check box.


Specifies the interface on which the traceroute packets are sent.

From the list, select the interface on which traceroute packets are sent. If you select any, the traceroute requests are sent on all interfaces.


Specifies the maximum time-to-live (TTL) hop count for the traceroute request packet.

From the list, select the TTL.


Specifies the type-of-service (TOS) value to include in the IP header of the traceroute request packet.

From the list, select the decimal value of the TOS field.

Resolve AS Numbers

Determines whether the autonomous system (AS) number of each intermediate hop between the device and the destination host is displayed.

  • To display the AS numbers, select the check box.
  • To suppress the display of the AS numbers, clear the check box.
