Important Considerations

■This tool is useful for network testing, performance measurement, and management. It uses the ICMP echo facility to send Internet Control Message Protocol (ICMP) echo request packets to the IP destination that you specify.

■If you need to change the default ping options, use the ip advancedPing option. (The command description for ip advancedPing lists the default ping options.)

■You can either supply the host name or IP address as part of the command string, or you can supply the information at the prompt.

■When you specify a host name, the host name and its associated IP address must be configured on a network name server. Also, you must add the IP address on the name server to the list of name server addresses that are associated with the network domain name. See “ip dns domainName” earlier in this chapter for more information.

■When the system sends an echo request packet to an IP station using ping, the system waits for an ICMP echo reply packet. Possible responses:

■If the host is reachable, the system displays information about the ICMP reply packets and the response time to the ping.

■If the host does not respond, the system displays the ICMP packet information and this message: Host is Not Responding. You may not have configured your gateway IP address.

■If the packets cannot reach the host, the system displays the ICMP packet information and this message: Host is Unreachable. A host is unreachable when there is no route to that host.

■To interrupt the command, press Enter.
