Connectivity Guide

● -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.
● 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 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.
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.
With the -I option, if you ping a reachable IP address using the IP address of a loopback interface as
the source interface, the ping succeeds. However, if you ping a reachable IP address using the name of
the loopback interface as the source interface, the ping fails. This is because the system considers the
loopback interface as the egress interface.
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
