• -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 IP addresses of the pre-specified hops for the ping packet to take. • target - Enter the IP address where you are testing connectivity. Default Command Mode Usage Information Not configured EXEC 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.
