I would like to ask a question what could be the reason and how to fix it
I have a switch 3560 and on one of the ports a PC is connected, the PC is shutdown but the interface light is on and its also shows up.
why its doing it any help would be appreciated
Typically, most of the modern day PC's keep their NIC cards active even when
the device is down (hibernate). As long as the loop is complete, the switch
shows that the interface is up. Can you remove the Ethernet cable from the
PC and see if the interface still stays up? You can also check the interface
status by issuing "show interface " command.
