Exit command to exit the configuration program and terminate communications with the switch for the current session Applications This switch segments your network significantly increasing both bandwidth and throughput Any port on the switch can be attached to a hub i e shared collision domain or provide a dedicated link to a single network device e g a workstation When a port on the switch is connected to an Ethernet hub i e a 10 or 100 Mbps repeater the bandwidth provided by that port is shared by all the devices connected to the attached hub However when a port is connected to an end node or to a device that breaks up the collision domain e g another switch bridge or router the attached device has access to the full bandwidth provided by that port Bridging Functions This switch provides fully transparent bridging functions which automatically learn node addresses that are subsequently used to filter and forward all traffic based on the destination address When traffic passes between devices attached to the same shared collision domain those packets are filtered from the switch But when traffic must be passed between unique segments i e different ports on the switch a temporary link is set up between the switch ports which need to pass this traffic via high bandwidth shared memory Switching Functions The scheme used to forward traffic to other ports can be configured to optimize system performance or to en
