Field Description
•
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 statistics for 1.1.2.2 ---
Statistics on data received and sent in the ping operation.
--- Ping statistics for 1.1.2.2 in VPN
instance vpn1 ---
Ping statistics for a device in a VPN instance.
5 packet(s) transmitted
Number of ICMP echo requests sent.
5 packet(s) received
Number of ICMP echo replies received.
0.0% packet loss
Percentage of unacknowledged packets to the total packets sent.
round-trip min/avg/max/std-dev =
4.685/4.761/4.834/0.058 ms
Minimum/average/maximum/standard deviation response time, in
milliseconds.

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. (The address selection rule is defined by RFC 3484.)
-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.
