IPv6 Diagnostic and Troubleshooting
Traceroute for IPv6
maxttl: Maximum number of hops allowed for each probe
packet sent along the route. Valid values: 1 - 255. Default: 30.
• If the maxttl value is less than the actual number of hops
required to reach the host, the traceroute output displays
only the IPv6 addresses of the hops detected by the
configured
maxttl value.
timeout: Number of seconds within which a response is
required from the IPv6 device at each hop in the route to the
destination host before the traceroute operation times out.
Default: 5 seconds; Range: 1 - 60.
probes: Number of times a traceroute is performed to locate
the IPv6 device at any hop in the route to the specified host
before the operation times out. Default: 3; Range: 1 - 5.
[source < ipv6-addr | vid >]: The source IPv6 address or VLAN
of the traceroute device or the VLAN-ID on which the
traceroute packet is being sent.

Destination IPv6 address
Intermediate router hops with
the time (in milliseconds) for
the switch to receive a
response from each of the
three probes sent to each
router.
At hop 3, the first and third probes timed
out, but the second probe reached the
router. Each timed-out probe is displayed
with an asterisk (*).
The four remaining probes within the
configured seven-hop maximum (maxttl)
also timed out without finding a next-hop
router or the destination IPv6 address.
