ping6

Tests network connectivity to an IPv6 device.

Syntax
ping6 [vrf management] [-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.
  • -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).
  • -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 ethernet node/slot/port ; for example, ethernet1/1/1.
    • For a VLAN interface, enter vlan vlan-id ; for example, vlan10.
    • For a loopback interface, enter loopback id ; for example, loopback1.
    • For a port-channel interface, enter port-channel channel-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) flag.
  • -p pattern — (Optional) Enter up to 16 pad bytes to fill out the packet you send to diagnose data-related problems in the network (for example,  -p ff fills 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 buffers 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-specified 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 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.
  • target — 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, followed by 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.
