Using the Trace Route Function
Use the IP > General > Trace Route page to show the route packets take to the
specified destination.
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
