The ping commandUsers can use the ping command to verify whether a device with a specified address isreachable, and to examine the network connectivity.Take the following steps when using the ping command:1) The source device sends ICMP ECHO-REQUEST packets to the destinationdevice.2) If the network is functioning properly, the destination device will respond bysending the source device ICMP ECHO-REPLY packets after receiving the ICMPECHO-REQUEST packets.3) If there is network failure, the source device will display information indicating thatthe address is unreachable.4) Display the relative statistics after execution of the ping command.Output of the ping command includes:z Information on how the destination device responds towards each ICMPECHO-REQUEST packet: if the source device has received the ICMPECHO-REPLY packet within the time-out timer, it will display the number of bytesof the ECHO-REPLY packet, the packet sequence number, Time To Live (TTL),and the response time.z If within the period set by the time-out timer, the destination device has notreceived the response packets, it will display the “Request time out.” information.z The ping command applies to the name and IP address of a destination device, ifthe device name is unknown, the “Error: Ping: Unknown host host-name”information will be displayed.
