Reference Guide

• -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 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.
• target — Enter the IPv6 destination address in A:B::C:D format, where you are testing connectivity.
Default Not congured
Command Mode EXEC
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 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.
Example
OS10# ping6 20::1
PING 20::1(20::1) 56 data bytes
64 bytes from 20::1: icmp_seq=1 ttl=64 time=2.07 ms
64 bytes from 20::1: icmp_seq=2 ttl=64 time=2.21 ms
64 bytes from 20::1: icmp_seq=3 ttl=64 time=2.37 ms
64 bytes from 20::1: icmp_seq=4 ttl=64 time=2.10 ms
