tion
Reply from 1.1.2.2 : bytes=56
Sequence=1 ttl=255 time=1 ms
Received the ICMP reply from the device whose IP address is 1.1.2.2. If
no reply is received during the timeout period, "Request time out" is
displayed.
• bytes—Number of data bytes in the ICMP reply.
• Sequence—Packet sequence, used to determine whether a segment is
lost, disordered or repeated.
• ttl—TTL value in the ICMP reply.
• time—Response time.
Record Route
Devices through which the ICMP echo request passed. They are
displayed in inversed order. The device with a smaller distance to the
destination is displayed first.
--- 1.1.2.2 ping statistics --- Statistics on data received and sent in the ping operation.
5 packet(s) transmitted Number of ICMP echo requests sent.
5 packet(s) received Number of ICMP echo requests received.
0.00% packet loss Percentage of packets not responded to the total packets sent.
round-trip min/avg/max = 0/4/20
ms
Minimum/average/maximum response time, in ms. The field is not
available for failed ping attempts in an IPv4 network. In an IPv6 network,
however, the field is available and set to 0/0/0 ms.
ping ipv6
Use ping ipv6 to verify whether an IPv6 address is reachable, and display the corresponding statistics.
Syntax
ping ipv6 [ -a source-ipv6 | -c count | -m interval | -s packet-size | -t timeout | -vpn-instance

Parameters
-a source-ipv6: Specifies the source IPv6 address of an ICMP echo request. It must be a valid IPv6
address configured on the device. If this parameter is not provided, the source IPv6 address of an ICMP
echo request is the IPv6 address of the outbound interface of the request. (The address selection rule is
defined by RFC 3484.)
-c count: Specifies the number of times that an ICMPv6 echo request is sent, which ranges from 1 to
4294967295 and defaults to 5.
-m interval: Specifies the interval (in milliseconds) to send an ICMPv6 echo reply, which ranges from 1
to 65535 and defaults to 200.
• If a response from the destination is received within the timeout time, the interval to send the next
echo request equals the actual response period plus the value of interval.
