Testing End-to-End Network Communications

Both the switch 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 switch. For example, if you
have two PCs on the network, both connected to the switch, you can
use a link-level packet test (link test) or Ping test to verify that the
entire communication path between the two PCs is functioning
correctly. See your LAN adapter documentation for more information
on running a link test or Ping test.
