the basic requirement of establising vlan is one manageable switch,two nodes in different vlans where we can communicate.we have to change default vlan0 in different vlans
TO avoide Single Broadcast into Network
switch is enough for creating vlan. if we need to create intervlan we need a router layer3 device to communicate betwwen vlans.
why do we need VLANS? because at switch level there is only one broadcast domain, it means whenever new user is connected to switch this information is spread throughout the network.
if we want our network information is restricted we should create VLAN on switch which creates separate broadcast domain at switch level. VLAN can be used as a security purpose.
1. A switch that supports 802.1Q Tagging.
2. Uplink Trunk Port to carry VLANS
3. Access Ports to Assign VLAN
LAN Switch that supports VLANs configuration eg.Cisco Switch
VLAN capable switch, and NIC
restrict the broadcast of the packets
for you to establish a VLAN network,you will need to have aequipment that will allow to connect on both ends. the role of this equipment is to allowthe information coming through the internet to be encrypted.you will also neeed to have the capacity to authenticate the users accessing your system.
the basic requirement of establishing vlan is confinement of broadcast domains on a network significantly reduces unwanted storms or traffic
