Reference 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 IP addresses of the pre-specified hops for the ping packet to take.
● target — Enter the IP address 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 IP and ICMP header, followed by a time value and
a number of ''pad'' bytes used to fill out the packet. A ping operation sends a packet to a specified IP
address and then measures the time it takes to get a response from the address or device.
If the destination IP address is active, replies are sent back from the server including IP address, number
of bytes sent, lapse time (in milliseconds), and time to live (TTL) which is the number of hops back from
the source to the destination.

ping6
Tests network connectivity to an IPv6 device.
Syntax
ping6 [vrf {management | vrf-name}] [-aAbBdDfhLnOqrRUvV] [-c count] [-i
interval] [-I interface] [-l preload] [-m mark] [-M pmtudisc_option] [-N
nodeinfo_option] [-p pattern] [-Q tclass] [-s packetsize] [-S sndbuf] [-t
ttl] [-T timestamp_option] [-w deadline] [-W timeout] destination
Parameters
● vrf management — (Optional) Pings an IPv6 address in the management VRF instance.
● vrf vrf-name — (Optional) Pings an IPv6 address in the specified VRF instance.
● -a — (Optional) Audible ping.
● -A — (Optional) Adaptive ping. An inter-packet interval adapts to the round-trip time so that not
more than one (or more, if preload option is set) unanswered probe is present in the network. The
minimum interval is 200 msec for a non-super-user, which corresponds to flood mode on a network
with a low round-trip time.
● -b — (Optional) Pings a broadcast address.
● -B — (Optional) Does not allow ping to change the source address of probes. The source address is
bound to the address used when ping starts.
● -c count — (Optional) Stops the ping after sending the specified number of ECHO_REQUEST
packets until the timeout expires.
● -d — (Optional) Sets the SO_DEBUG option on the socket being used.
● -D — (Optional) Prints the timestamp before each line.
● -F flowlabel — (Optional) Sets a 20-bit flow label on echo request packets. If value is zero, the
kernel allocates a random flow label.
● -h — (Optional) View help for this command.
● -i interval— (Optional) Enter the number of seconds to wait before sending the next packet (0 to
60, default 1).
