you are you running it. its replying back with the wreck or placing gas
I'm running I P my house is alive so this is telling me a couple things than
about what's going on in the communication between them if we look at this
within the scope of the OS I modeled that we talked about before ICMP is
working at the network layer it's a layer 3protocol that runs on top of the
other restive the layer to you and the layer one network so this protocol with
the other paintings is a good test just to make sure that the physical can
activity between the devices so we would say that this is our Windows machine
and this was this is really switch to you here but I now know that there's nothing
wrong in the physical layer between them so some others there’s physical
connectivity somehow there's also Ethernet connectivity which is running at
layer 2 and I now know I have collectively up to at least layer 3 now this tool
king is probably one of the most basic network testing tools there is out there
is just going to tell us that there's nothing wrong with the physical network
under in it's also going to tell us that if the devices are not on the same
subnet that the IQ routing feature is working between a so we’ll talk about
that in more detail when we get to routing about if the Windows machine and
switched you were 642-813 not on the same subnet but they were still able to ping each
other it means routings fine now right now they are on the same subnet so they
don't need to route to reach each other they're just going to have our local
can activity and what's known as the broadcast domain is where people who are
sharing the same subnet are going to be now this doesn't necessarily tell me
that there applications.
