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 communi-

cation 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.

See your LAN adapter card’s manual for information on running an end-to-end

communication test.

With the AdvanceStack 8U/16U SNMP module, you can also run a Link test

directly to or from a hub (directly between a hub and another device, rather

than just through the hub).
