The ping command is a good tool for troubleshooting Layers 1 though 3 of the OSI model and diagnosing basic network connectivity. Using ping sends an ICMP packet to the specified device (workstation, server, router or switch) and then waits for a reply. The IP address or host name can be pinged. In order to ping the host name of a router, there must be a static host lookup table in the router or a DNS server for name resolution to IP addresses.
