Using the Trace Route Function
– 563 –
USING THE TRACE ROUTE FUNCTION
Use the IP > General > Trace Route page to show the route packets take to
the specified destination.
CLI REFERENCES
◆ "traceroute" on page 1400
PARAMETERS
These parameters are displayed:
◆ Destination IP Address – IPv4/IPv6 address of the host.
◆ IPv4 Max Failures – The maximum number of failures before which
the trace route is terminated. (Fixed: 5)
◆ IPv6 Max Failures – The maximum number of failures before which
the trace route is terminated. (Range: 1-255; Default: 5)
COMMAND USAGE
◆ Use the trace route function to determine the path taken to reach a
specified destination.
◆ A trace terminates when the destination responds, when the maximum
timeout (TTL) is exceeded, or the maximum number of hops is
exceeded.
◆ The trace route function first sends probe datagrams with the TTL value
set at one. This causes the first router to discard the datagram and
return an error message. The trace function then sends several probe
messages at each subsequent TTL level and displays the round-trip
time for each message. Not all devices respond correctly to probes by
returning an “ICMP port unreachable” message. If the timer goes off
before a response is returned, the trace function prints a series of
asterisks and the “Request Timed Out” message. A long sequence of
these messages, terminating only when the maximum timeout has
been reached, may indicate this problem with the target device.
◆ The same link-local address may be used by different interfaces/nodes
in different zones (RFC 4007). Therefore, when specifying a link-local
address, include zone-id information indicating the VLAN identifier after
the % delimiter. For example, FE80::7272%1 identifies VLAN 1 as the
interface from which the trace route is sent.
WEB INTERFACE
To trace the route to another device on the network:
1. Click IP, General, Trace Route.
2. Specify the target device.
3. Click Apply.
