Once you have created the preceding topology, configure the appropriate IP addresses on each PCs.
We will use the following topology to demonstrate how to configure VLANs. The following table lists the details of topology that we will use. In this exercise, we will configure VLANs on Switch1 and Switch2. In addition, one can also use the vlan database command in the privileged mode. To configure VLANs on a Cisco switch, use the vlan global configuration command. This method is preferred for the large networks.
Dynamic VLAN: VLANs database can be configured and updated with the help of a protocol called VTP (VLAN Trunking Protocol) automatically or with the least user interaction. This method is preferred for a small network. Static VLAN: In this method, an administrator needs to configure and update VLAN database manually each time. 
There are two methods that can be used to configure VLANs. VLAN 1 is the default VLAN (native VLAN) that is used for the administrative purpose.Ĭisco manageable switches allow you to configure VLANs as per your network requirements. The range of VLAN ID can vary from 1-1005.
VLANs increase the number of broadcast domains.Įach VLAN is identified by a unique identification number called VLAN ID. VLANs are typically independent to the users’ physical or geographic locations. VLANs allow you to create a logical group of users by function. VLANs allow you to add, move, and change networks with ease by just configuring a port into the appropriate VLAN. Some of the key features provided by VLANs are: In this post, we will explain the key features provides by VLANs and how to configure VLANs on cisco switches. VLANs provide a number advantages and features. It is absolutely essential to follow the steps in strict order.VLANs are used to segment a large physical LAN into multiple small virtual LANs for better management and greater security. However, for professionals in the telecommunications sector it does not have too much difficulty. It is a somewhat complex procedure which is part of design and installation of industrial or domestic networksWhich it requires advanced knowledge in information technology to do it correctly. Here are the steps to follow for the c ONFIGURATION a VLAN on Cisco Switch. To delete all VLANs they have been created on a Cisco Switch you just have to delete the vlan.dat file stored in flash memory swtich. To clear the VLAN 10 use SW1 (config) # no VLAN 10. The fourth step on Deleting a VLANBegins to enter privileged mode using the command SW1 # configure terminal. The next step is to initialize the interface with switch SW1 (config-if) # no shutdown. Then the interface in the "access" mode via SW1 (config-if) #switchport mode access is configured.įor allocate the interface to VLAN 20The command set is SW1 (config-if) #switchport access vlan 20. Step # 3: How to assign a port to a VLANįor assign a port to a VLANThe first thing we have to achieve is to enter configuration mode interface with #interface SW1 F0 / 1 command (config). There comes a time to set the label "ENGLISHENVIVO" to VLAN 30 by SW1 (config-vlan) #name ENGLISHENVIVO and exit to the previous configuration mode SW1 (config-vlan) #exit. We proceed with setting the label called "CISCO" VLAN SW1 20 by the command (config-vlan) #name CISCO and goes back to the previous configuration SW1 (config-vlan) #exitįor create VLAN 30The command set is SW1 (config) #vlan 30. 
The next step for create VLAN 20, Will enter the following command: SW1 (config) #vlan 20. Then, SW1 (config-vlan) #name CAPACITY indicated to set the "capaciy" tag VLAN 10 and SW1 (config-vlan) # exit to exit configuration mode above. The next step is to set the SW1 # configure terminal command to enter privileged mode and SW1 (config) #vlan 10 for create VLAN 10. Then the SW1 # show vlan command is used to display on the screen created in those VLANs Cisco IOS.
SW1> enable command is selected to enter the privileged mode. Obviously, it is important to follow all of them in strict order for the LAN configuration it is done correctly. Listed below are all the steps to perform this procedure, which is much easier than it might seem. How to configure una VLAN en Cisco Switch? Thus, it is interesting to know how a VLAN configuration is performed on Cisco Switch. Importantly, those devices belonging to VLANs different can not communicate with each other. It is therefore a grouping of a set of devices that can maintain communication with each other. It is known as Virtual LAN o VLAN a division of logical character in the broadcast domain level Layer 2 of the OSI model.
