VLAN (Virtual LAN) VLAN is a Layer 2method that allowsmultiple Virtual LANson a single physicalinterface.You can also transportVLANs over wired andwireless links and putmultiple VLANinterfaces on a singlewireless interfaceEUTCMUM Yogyakarta 19-20 Oct 201810
VLAN Each VLAN is treatedas a separate subnet.It means that bydefault, a host in aspecific VLAN cannotcommunicate with ahost that is a memberof another VLAN,although they areconnected in the sameswitch.EUTCMUM Yogyakarta 19-20 Oct 201811
Why VLAN ?We can create multiple LAN in a singlephysical interface, so we will have multiplebroadcast domain in a single physicalinterface We can manage the local network moresimple and manage the different network inone single interface We can create multiple vlan-id in oneinterface (Trunk) OR multiple interface forone vlan-id (Access) EUTCMUM Yogyakarta 19-20 Oct 201812

Conclusion & Discussion Bridging vlan (wired and wireless) makes networkmanagement easier and centralized.VLAN could be put or attached in bridge orphysical interface.When you add an interface to a bridge, the bridgebecomes the master interface and all bridge portsbecome slave ports, this means that all traffic thatis received on a bridge port is captured by thebridge interface and all traffic is forwarded to theCPU using the bridge interface instead of thephysical interface.EUTCMUM Yogyakarta 19-20 Oct 201879
Conclusion & Discussion With bridges, it is easy to show and manage thetrunk port or access port.Always disable VLAN filtering first, before youare sure about your VLAN setting !Always give the specific IP to the bridges forease of maintenance and trouble-shooting.Bridging in wireless, we should use stationbridge or bridge mode, don't use station onlymode.The disadvantage of wds and repeater link is thereduction of the throughput on the wireless side.EUTCMUM Yogyakarta 19-20 Oct 201880
