Connectivity Guide

• -F flowlabel — (Optional) Sets a 20-bit ow label on echo request packets. If value is zero, the kernel
allocates a random ow label.
• -h — (Optional) Displays help for this command.
• -i interval — (Optional) Enter the interval in seconds to wait between sending each packet, the default
is 1 second.
• -I interface-name or interface-ip-address — (Optional) Enter the source interface name
without spaces or the interface IP address:
– 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-channel.
• -l preload — (Optional) Enter the number of packets that ping sends before waiting for a reply. Only a
super-user may preload more than three.
• -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 this option 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) ag.
• -p pattern — (Optional) Enter a maximum of 16 pad bytes to ll out the packet you send to diagnose data-
related problems in the network; for example, -p ff lls the sent packet with all 1’s.
• -Q tos — (Optional) Enter a maximum of 1500 bytes in decimal or hex datagrams to set the quality of
service (QoS)-related bits.
• -s packetsize — (Optional) Enter the number of data bytes to send, from 1 to 65468, default 56.
• -S sndbuf — (Optional) Set the sndbuf socket. By default, the sndbuf socket buers one packet maximum.
• -t ttl — (Optional) Enter the IPv6 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-specied hops).
• -v — (Optional) Verbose output.
• -V — (Optional) Display the 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 aects 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-specied hops for the ping packet to take.
• destination — 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, then a time value and a number of ''pad'' bytes
used to ll out the packet. A pingv6 operation sends a packet to a specied IPv6 address and then measures the
time it takes to get a response from the address or device.
When you use the -I option and enter an IP address, OS10 considers it as the source address. If you use an
interface name instead of the IP address, OS10 considers it as the egress interface.
