HP MSR1003-8S Command Reference Manual page 17

-c count: Specifies the number of ICMPv6 echo requests that are sent to the destination. The value range
is 1 to 4294967295, and the default is 5.
-i interface-type interface-number: Specifies the source interface for ICMPv6 echo requests. This option
must be specified when the destination address is a multicast address or a link local address. If you do
not specify this option, the system uses the primary IP address of the matching route's egress interface as
the source interface for ICMPv6 echo requests.
-m interval: Specifies the interval (in milliseconds) to send an ICMPv6 echo reply. The value range is 1
to 65535, and the default is 1000.
-q: Displays only the summary statistics. If you do not specify this keyword, the system displays all the
ping statistics.
-s packet-size: Specifies the length (in bytes) of ICMPv6 echo requests (excluding the IPv6 packet header
and the ICMPv6 packet header). The value range is 20 to 8100, and the default is 56.
-t timeout: Specifies the timeout time (in milliseconds) of an ICMPv6 echo reply. The value range is 0 to
65535, and the default is 2000.
-tc traffic-class: Specifies the traffic class value in an ICMPv6 packet. The value range is 0 to 255 and the
default is 0.
-v: Displays detailed information (including the dst field and the idx field) about ICMPv6 echo replies. If
this keyword is not specified, the system only displays brief information (not including the dst field and the
idx field) about ICMPv6 echo replies.
-vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance to which the destination belongs,
where the vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. If the destination
is on the public network, do not specify this option.
host: Specifies the IPv6 address or host name of the destination. The host name is a case-insensitive string
of 1 to 253 characters. It can contain letters, digits, and special characters such as hyphen (-), underscore
(_), and dot (.).
Usage guidelines
To use the name of the destination host to perform the ipv6 ping operation, you must first configure DNS
on the device. Otherwise, the ipv6 ping operation fails.
To abort the ping ipv6 operation during the execution of the command, press Ctrl+C.
Examples
# Test whether the IPv6 address (2001::2) is reachable.
<Sysname> ping ipv6 2001::2
Ping6(56 data bytes) 2001::1 --> 2001::2, press CTRL_C to break
56 bytes from 2001::2, icmp_seq=0 hlim=64 time=62.000 ms
56 bytes from 2001::2, icmp_seq=1 hlim=64 time=23.000 ms
56 bytes from 2001::2, icmp_seq=2 hlim=64 time=20.000 ms
56 bytes from 2001::2, icmp_seq=3 hlim=64 time=4.000 ms
56 bytes from 2001::2, icmp_seq=4 hlim=64 time=16.000 ms
--- Ping6 statistics for 2001::2 ---
5 packet(s) transmitted, 5 packet(s) received, 0.0% packet loss
round-trip min/avg/max/std-dev = 4.000/25.000/62.000/20.000 ms
# Test whether the IPv6 address (2001::2) is reachable. Only the statistics are displayed.
