(IP) Using the Ping Command

Ping is used to diagnose network problems dealing with availability and response time. The Ping command sends an echo request to a foreign node to determine if the computer is accessible. When the response to the Ping command is received, the elapsed time is displayed. The time does not include the time spent communicating between the user and the TCP/IP address space.

The following parameters are available for the Ping command:

Address/Name

Local or remote host to which the echo request is sent. If you fail to enter a host name, the system prompts for one. Enter either the IP address or the character-string name for the host.

Bytes to Send

Default=256. Sets the number of bytes sent in the echo request. Valid values are a minimum of 8 and a maximum determined by the lrg_env_size value set in the PROFILE.TCPIP data set.

Times to Send

Valid values are 0 to 2,147,483,647. Sets the number of echo requests that are sent to the host. If the count is zero (0), PING continually sends requests. To stop the PING command, press PA1.

Timeout

Default=10 seconds. Sets the number of seconds that the PING command waits for a response. Valid values are 1 to 100.

The Commands module provides the following PING command formats:

PING – Use Defaults

Use the PING command with the defaults listed above.

PING – Change Parameters
