• -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 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) 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 timeout 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. 694 Troubleshoot OS10
