In an enterprise environment if there is a bunch of workstations connected to a catalyst switch with a transceiver in between, and one particulary switchport shows up/up with 2-3 packets input and 10+ output, no errors on the interface, but can't ping the workstation IP, is it possible that the workstation is turned off?
I had thought if the workstation was turned off the port would show down/down (notconnect), but then I thought maybe if it's going to a transceiver first it would show up/up. Even if the siwtchport is plugged into a workstation that's turned off, isn't there still electricity/frames/anything constantly transmitting across the wire?
If the switchport is up/up and passing traffic but the workstation cannot be pinged the only other thing I can think of is bad DHCP pool because ISE/ip helper checks out
