Procedure 6: Pinging the TCP/IP Interfaces on the Network

PING (Packet InterNet Grouper) is the name of a program used in the Internet to test reachability of destinations by sending them an ICMP echo request and waiting for a reply. Most hosts, as nodes on the Internet are called, including the Ethernet Interface, implement a PING command.

The user should ping each installed Ethernet Interface. When the Ethernet Interface re- sponds to the ping, it verifies that the interface is operational and configured properly. Specifically it verifies that acceptable configuration information and communications software have been downloaded to the interface.

The ping can be executed from a UNIX host or PC (most TCP/IP communications soft- ware provides a PING command) or from an Ethernet Interface. When using a PC, the user can refer to the documentation for the PING command, but in general all that is re- quired is the IP address of the remote host as a parameter to the PING command. For example, ªping 3.0.0.1º.

Perform the following steps to ping from an Ethernet Interface.

1.Connect the GSM locally to one of the Ethernet Interfaces. Refer to Using the GSM ªAccess Station Managerº Function in Procedure 2.

2.Enter the NODE command to verify that the local interface has the correct IP address.
