56 bytes from 1.1.2.2: icmp_seq=0
ttl=254 time=4.685 ms
Received ICMP echo replies
from the device whose IP address is
1.1.2.2. If no echo reply is received within the timeout period, no
information is displayed.
• bytes—Number of bytes in the ICMP echo reply.
• icmp_seq—Packet sequence
, used to determine whether a
segment is lost, disordered or repeated.
• ttl—TTL value in the ICMP echo reply.
• time—Response time.
RR:
Routers through which the ICMP echo request passed. They are
displayed in inversed order, which means the router with a smaller
distance to the destination is displayed first.

ping ipv6
Use ping ipv6 to test the reachability of the destination IPv6 address and display IPv6 ping statistics.

Parameters
-a source-ipv6: Specifies an IPv6 address of the device as the source IP address of ICMP echo
requests. If this option is not specified, the source IPv6 address of ICMP echo requests is the IPv6
address of the outbound interface. See RFC 3484 for information about the address selection rule.
-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.
