• A vlan virtual local area network allows a physical network to be partitioned into multiple logical networks devices on a logical network belong to one group a device can belong to more than one group with vlan a device cannot directly talk to or hear from devices that are not in the same group s the traffic must first go through a router p.63
• Vlan also increases network performance by limiting broadcasts to a smaller and more manageable logical broadcast domain in traditional switched environments all broadcast packets go to each and every individual port with vlan all broadcasts are confined to a specific broadcast domain p.63
• Note vlan is unidirectional it only governs outgoing traffic p.63
• Label description p.63
• Introduction to vlans p.63

• For example an isp internet services provider may divide different types of services it provides to customers into different ip subnets traffic for voice services is designated for ip subnet 172 6 24 video for 192 68 24 and data for 10 24 the switch can then be configured to group incoming traffic based on the source ip subnet of incoming frames p.93
• Chapter 9 vlan p.93
• You configure a subnet based vlan with priority 6 and vid of 100 for traffic received from ip subnet 172 6 24 voice services you also have a subnet based vlan with priority 5 and vid of 200 for traffic received from ip subnet 192 68 24 video services lastly you configure vlan with priority 3 and vid of 300 for traffic received from ip subnet 10 24 data services all p.93
• Vlan port set up p.93
• Subnet based vlans allow you to group traffic into logical vlans based on the source ip subnet you specify when a frame is received on a port the switch checks if a tag is added already and the ip subnet it came from the untagged packets from the same ip subnet are then placed in the same subnet based vlan one advantage of using subnet based vlans is that priority can be assigned to traffic from the same ip subnet p.93

• Port based vlans require allowed outgoing ports to be defined for each port therefore if you wish to allow two subscriber ports to talk to each other for example between conference rooms in a hotel you must define the egress an egress port is an outgoing port that is a port through which a data packet leaves for both ports p.97

• Voice vlan ensures that the sound quality of an ip phone is preserved from deteriorating when the data traffic on the switch ports is high it groups the voice traffic with defined priority into an assigned vlan which enables the separation of voice and data traffic coming onto the switch port p.100
