MAC-based VLAN Groups Overview - For instructions on how to configure subnet-based VLAN Groups through the web-based utility of your switch, click here. (Optional) You can also configure the following: For instructions on how to configure subnet-based VLAN Groups through the web-based utility of your switch, click here.Ĥ. If the interface does not belong to the VLAN, the subnet-based groups to VLAN configuration setting will not take effect.ģ. For instructions on how to assign interfaces to VLANs through the web-based utility of your switch, click here. For CLI-based instructions, click here.Ģ.

Protocol-based VLAN - The VLAN is recognized from the Ethernet type Protocol-to-VLAN mapping of the ingress interface.Subnet-based VLAN - The VLAN is recognized from the source Subnet-to-VLAN mapping of the ingress interface.MAC-based VLAN - The VLAN is recognized from the source Media Access Control (MAC)-to-VLAN mapping of the ingress interface.Tag - The VLAN number is recognized from the tag.Many different classifications exist, and if more than one classification scheme is defined, the packets are assigned to the VLAN in this order: The packets are distributed with respect to different classifications and are assigned to VLANs. VLAN groups are used to load balance the traffic on a Layer 2 network. For this reason, you cannot take advantage of the many features of VLAN. Non-standard devices are used to pass traffic between different VLANs in order to include the devices participating in a specific protocol. Networking devices on which multiple protocols are running cannot be grouped to a common VLAN. VLANs can also be used to enhance performance by reducing the need to send broadcasts and multicasts to unnecessary destinations.

Only users that belong to a VLAN are able to access and manipulate the data on that VLAN. In scenarios where sensitive data may be broadcast on a network, VLANs can be created to enhance security by designating a broadcast to a specific VLAN. The next step is configuring Inter-VLAN Routing. I hope you find this article helpful and do comment us about the qualities and improvements of Technig articles.A Virtual Local Area Network (VLAN) allows you to logically segment a Local Area Network (LAN) into different broadcast domains. Now you can set up VLAN on your network Switches. Finally type “ do sh vlan” and see the result again. SW2(config-if-range)#switchport access vlan 4Ħ. SW2(config-if-range)#switchport mode access SW2(config)#interface range fastEthernet 0/2-4 In this method, we add each interface one by one, but you can use “ Interface range” command to add a group of ports to a VLAN. I have added the and to VLAN 2 which is our Marketing VLAN. So try to add an interface to a VLAN with the “ Switchport” command. All the Interfaces ports are within the default VLAN and not yet grouped to Marketing, Accounting, and Sales. Now try to add interfaces to each of these VLANs. You see the VLANs are created successfully.ĥ. Just type the “ do sh vlan” command from config mod to see whether VLANs are created or not. Now create the VLANs using “ VLAN” command. First, change the switch name with “ hostname” command.Įnter configuration commands, one per line. Open the VLAN lab and create these three VLAN and named Marketing, Accounting, and Sales. So let’s create them with the following commands.Ģ.

You can download the VLAN Lab or create your lab within Cisco packet tracer or other network simulators.

Let’s start to configure VLAN on Cisco switch using Cisco Packet Tracer. Read more about VLAN on Cisco Packet Tracer CCNA Lab. Here we just configure VLAN on Cisco switch and not talking about VTP, STP, and other advanced Switching techniques.

Because a VLAN is considered a separate logical network. Any switch port can belong to a VLAN, and unicast, broadcast, and multicast packets are forwarded and flooded only to end stations in the VLAN.Įach VLAN is considered a logical network, and packets destined for stations that do not belong to the VLAN must be forwarded through a router or bridge or layer 3 switches. VLANs have the same attributes as physical LANs, but you can group computers even if they are not physically located on the same LAN segment. A VLAN is a switched network that is logically segmented by function, project team, or application, without regard to the physical locations of the users. This is how to configure VLAN on Cisco Switch or Virtual LAN on Cisco Switches in your network.
