<ol><li class="stepexpand"><span>At the command line, type these commands:</span><ul><li>For IPv4:<samp class="codeph"> PING 'nnn.nnn.nnn.nnn'</samp> or <samp class="codeph">PING <em>hostname</em></samp></li>
|

<li>For IPv6:<samp class="codeph"> PING 'x:x:x:x:x:x:x:x'</samp> or <samp class="codeph">PING <em>hostname</em></samp></li>

See Ping parameters to fine-tune the Ping command to get the most accurate
|

|
|
results. Prompt on the Ping command by selecting F4 for complete details on
|
||
|
|
the Ping parameters.</li>
|
||
|
|
<li class="stepexpand"><span>Failures might indicate the following problems:</span><ul><li>TCP/IP has not been started. To start TCP/IP, type <samp class="codeph">STRTCP</samp> (Start
|
||
|
|
TCP/IP) at the command line.</li>
|
||
|
|
<li>The remote system is not available.</li>
|
||
|
|
<li>A frame size problem. The frame size on the line description should
|
||
|
|
be greater than or equal to the maximum transmission unit (MTU) of the interface.</li>
|
||
|
|
<li>A network, router, next hop, or bridge problem.</li>
|
||
|
|
<li>The default route is not configured on your server.</li>
|
||
|
|
<li>The remote system or intermediate firewall has ICMP Echo requests
|
||
|
|
or replies disabled.</li>
|
||
|
|
<li>If you have multiple IP addresses and subnets, make sure that IP datagram
|
||
|
|
forwarding is set to *YES.</li>
|
||
|
|
<li>If the interface you are trying to reach is configured to an Ethernet
|
||
|
|
adapter, you might need to change the Ethernet standard in the Ethernet line
|
||
|
|
description. Specify either the correct Ethernet standard or *ALL.</li>
|
||
|
|
<li>A DNS or host name table problem. For example, if the Ping works for
|
||
|
|
the interface's IP address but not the host or domain name, you need to check
|
||
|
|
your host table or DNS entries.</li>
