Testing End-to-End Network Communications

Both the hub and the cabling can be tested by running an end-to-end
communications test — a test that sends known data from one network
device to another through the hub — such that you can verify that the data
was correctly transmitted between the devices. For example, if you have
two PCs on the network that have HP LAN adapter cards, you can use the
"Link Test" option from the card's test program to verify the entire
communication path between the two PCs. In the following illustration, two
computers are connected together with twisted-pair cable to two different
ports on the hub.
