Reference Guide

● -i interval — (Optional) Enter the interval, in seconds, to wait between sending each packet
(default 1 second).
● -I interface-address — (Optional) Enter the source interface address (with no spaces):
○ For a physical Ethernet interface, enter ethernetnode/slot/port; for example,
ethernet1/1/1.
○ For a VLAN interface, enter vlanvlan-id; for example, vlan10.
○ For a loopback interface, enter loopbackid; for example, loopback1.
○ For a port-channel interface, enter port-channelchannel-id; for example, port-
channel1.
● -l preload — (Optional) Enter the number of packets that ping sends before waiting for a reply.
Only a super-user may preload more than 3.
● -L — (Optional) Suppress the loopback of multicast packets for a multicast target address.
● -m mark — (Optional) Tags the packets sent to ping a remote device (use with policy routing).
● -M pmtudisc_option — (Optional) Enter the path MTU (PMTU) discovery strategy:
○ do prevents fragmentation, including local.
○ want performs PMTU discovery and fragments large packets locally.
○ dont does not set the Don’t Fragment (DF) flag.
● -p pattern — (Optional) Enter up to 16 pad bytes to fill out the packet you send to diagnose
data-related problems in the network (for example, -p ff fills the sent packet with all 1’s.
● -Q tos — (Optional) Enter the number of datagrams (up to 1500 bytes in decimal or hex) to set
quality of service (QoS)-related bits.
● -s packetsize — (Optional) Enter the number of data bytes to send (1 to 65468, default 56).
● -S sndbuf — (Optional) Set the sndbuf socket. By default, the sndbuf socket buffers one packet
maximum.
● -t ttl — (Optional) Enter the IP time-to-live (TTL) value in seconds.
● -T timestamp option — (Optional) Set special IP timestamp options. Valid values for timestamp
option — tsonly (only timestamps), tsandaddr (timestamps and addresses) or tsprespec
host1 [host2 [host3 [host4]]] (timestamp pre-specified hops).
● -v — (Optional) Verbose output.
● -V — (Optional) Display version and exit.
● -w deadline — (Optional) Enter the time-out value, in seconds, before the ping exits regardless of
how many packets are sent or received.
● -W timeout — (Optional) Enter the time to wait for a response, in seconds. This setting affects the
time-out only if there is no response, otherwise ping waits for two round-trip times (RTTs).
● hop1 ... (Optional) Enter the IPv6 addresses of the pre-specified hops for the ping packet to take.
● target — Enter the IPv6 destination address in A:B::C:D format, where you are testing connectivity.

Usage
Information
This command uses an ICMP ECHO_REQUEST datagram to receive an ICMP ECHO_RESPONSE from a
network host or gateway. Each ping packet has an IPv6 and ICMP header, followed by a time value and a
number of ''pad'' bytes used to fill out the packet. A pingv6 operation sends a packet to a specified IPv6
address and then measures the time it takes to get a response from the address or device.
