IPv6 Configuration Guide K/KA/KB.15.15

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.
dstport 1 - 34000
Destination port.
srcport 1 - 34000
Source port.
Example 209 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
First three hops
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.
Last hop
Destination IPv6 address
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.
DNS Resolver for IPv6
The Domain Name System (DNS) resolver is designed for local network domains where it enables
use of a host name or fully qualified domain name to support DNS-compatible commands from
the switch. Beginning with software release K.13.01, DNS operation supports these features:
• dual-stack operation: IPv6 and IPv4 DNS resolution
• DNS-compatible commands: ping, ping6, traceroute, and traceroute6
• multiple, prioritized DNS servers (IPv4 and IPv6)
