Restricting the users from accessing a set of services within the local area network is called port blocking.
we,ll give you the fine example its nothing but we have to block the switch port with particular maC address..for example we have 8-port switch ,in that first port we connected a machine that belongs to this mac address {4e5a.23bf.34ae.9a4c} and we block the switch port with this mac address for instance you unplug the original host and plug the other one now your new machine will be prevented from accessing switch port thats the idea.... so if u enabling port blocking command in a switch only particular machine or intented machine allow to use access ,other machine will be restricted... port blocking is used for security purpose...otherwise some intruders enter into your company and destroy your lan with single laptop thats it
