The traceroute6
command enables you to trace the route from a switch to a host device that is identified by an IPv6 address or IPv6 host name. In the command output, information on each (router) hop between the switch and the destination IPv6 address is displayed.
To use a traceroute6
command with an IPv6 host name or fully qualified domain names, see DNS resolver for IPv6.
Note that each time you perform a traceroute operation, the traceroute
command uses the default settings unless you enter different values with each instance of the command.
Replies to each traceroute operation are displayed on the console screen. To stop a traceroute operation before it finishes, press [Ctrl] [C].
For more information about how to configure and use a traceroute operation, see the Management and Configuration Guide.

Lists the IPv6 address of each hop in the route to the specified destination host device with the time (in microseconds) required for a packet reply to be received from each next-hop device.
IPv6 traceroute probes
HP Switch# traceroute6 2001:db8::10 traceroute to 2001:db8::10 1 hop min, 30 hops max, 5 sec. timeout, 3 probes 1 2001:db8::a:1c:e3:3 0 ms 0 ms 0 ms 2 2001:db8:0:7::5 7 ms 3 ms 0 ms 3 2001:db8::214:c2ff:fe4c:e480 0 ms 1 ms 0 ms 4 2001:db8::10 0 ms 1 ms 0 ms
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.
HP Switch# traceroute6 2001:db8::10 maxttl 7 traceroute to fe80::1:2:3:4 1 hop min, 7 hops max, 5 sec. timeout, 3 probes 1 2001:db8::a:1c:e3:3 0 ms 0 ms 0 ms 2 2001:db8:0:7::5 0 ms 0 ms 0 ms 3 * 2001:db8::214:c2ff:fe4c:e480 * 4 * * * 5 * * * 6 * * * 7 * * *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.
