Using the ping and tracert Commands
Ethernet networking is the backbone for the PortServer and PortServer Pro
workgroups. If your Ethernet network is not performing properly, it will affect
your workgroup. The following sections describe how to use two commands,
ping and tracert, to troubleshoot your network.
ping
You can use the ping command to confirm that the physical and logical
aspects of your network are configured correctly.
Physical aspects include
network interface card, cables, and Ethernet switches. Logical aspects include
IP addresses, subnet masks, and routing.
ping works by sending a packet over the network from an originating host to a
destination host. The destination host receives the packet and sends a response
packet over the network to the originating host. If the originating host receives
the response packet, it is a good indication that the network is configured
correctly.
You can use many options with ping. This section discusses two types of ping
syntax:
ping [System Name]
where [System Name] is the network name of the remote system to which
you are testing connectivity
or
ping [IP Address]
where [IP Address] is the IP address of the remote system to which you
are testing connectivity.
To run the ping command:
1. Open an MS-DOS
®
command prompt window.
2. At the command line, type the ping command (for example,
ping 192.168.10.5
).
