Pass4sure CCNA:Set Idle time-out time for cisco layer 2 switch

Layer 2 switch is A network device that forwards traffic based on MAC layer (Ethernet or Token Ring) addresses. Bridging technology has been around since the 1980s (and maybe even earlier). Bridging involves segmentation of local-area networks (LANs) at the Layer 2 level. A multiport bridge typically learns about the Media Access Control (MAC) addresses on each of its ports and transparently passes MAC frames destined to those ports. These bridges also ensure that frames destined for MAC addresses that lie on the same port as the originating station are not forwarded to the other ports. For the sake of this discussion, we consider only Ethernet LANs.
