Reference Guide

• -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 ood 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 specied 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 ow label on echo request packets. If value is zero, the kernel
allocates a random ow 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).
• -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) ag.
• -p pattern — (Optional) Enter up to 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 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 buers 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-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.
