• Vlan is generally divided by ports this way of division is simple but isn t suitable for those networks that require frequent topology changes with the popularity of mobile office a terminal device may access the switch via different ports for example a terminal device that accessed the switch via port 1 last time may change to port 2 this time if port 1 and port 2 belong to different vlans the user has to re configure the switch to access the original vlan using mac vlan can free the user from such a problem it divides vlans based on the mac addresses of terminal devices in this way terminal devices always belong to their original vlans even when their access ports change 191

• Configuring dhcp relay 450
• Part 15 450
• Dhcp relay is used to process and forward dhcp packets between different subnets 451
• Dhcp relay solves this problem as the following figure shows the dhcp relay device acts as a relay agent and forwards dhcp packets between dhcp clients and dhcp servers on different subnets so that dhcp clients on different subnets can share one dhcp server 451
• Overview 451
• Since the client requests a dynamic ip address via broadcast the basic network model of dhcp requires that the client and the server should be on the same lan therefore each lan should be equipped with a dhcp server thus increasing the costs of network construction 451

• Part 18 508
• Overview 509
• Because the voice vlan in automatic mode supports only tagged voice traffic you need to make sure traffic from the voice device is tagged to do so there are mainly two ways 511
• Before configuring voice vlan you need to create a vlan for voice traffic for details about vlan configuration please refer to configuring 802 q vlan 511
• Configuration guidelines 511
