It is known as Virtual LAN o VLAN a division of logical character in the broadcast domain level Layer 2 of the OSI model. It is therefore a grouping of a set of devices that can maintain communication with each other.

Importantly, those devices belonging to VLANs different can not communicate with each other. Thus, it is interesting to know how a VLAN configuration is performed on Cisco Switch.

How to configure una VLAN en Cisco Switch?

Listed below are all the steps to perform this procedure, which is much easier than it might seem. Obviously, it is important to follow all of them in strict order for the LAN configuration it is done correctly.

Step # 1: How to display on-screen VLANs

SW1> enable command is selected to enter the privileged mode. Then the SW1 # show vlan command is used to display on the screen created in those VLANs Cisco IOS.

Step 2: Creating a VLAN

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, SW1 (config-vlan) #name CAPACITY indicated to set the "capaciy" tag VLAN 10 and SW1 (config-vlan) # exit to exit configuration mode above.

Creating a VLAN on Cisco

The next step for create VLAN 20, Will enter the following command: SW1 (config) #vlan 20.

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) #exit

For create VLAN 30The command set is SW1 (config) #vlan 30. 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.

Step # 3: How to assign a port to a VLAN

For 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). Then the interface in the "access" mode via SW1 (config-if) #switchport mode access is configured.

For allocate the interface to VLAN 20The command set is SW1 (config-if) #switchport access vlan 20. The next step is to initialize the interface with switch SW1 (config-if) # no shutdown.

Step # 4: Deleting a VLAN

The fourth step on Deleting a VLANBegins to enter privileged mode using the command SW1 # configure terminal. To clear the VLAN 10 use SW1 (config) # no VLAN 10.

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.

Here are the steps to follow for the cONFIGURATION a VLAN on Cisco Switch. 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.

However, for professionals in the telecommunications sector it does not have too much difficulty. It is absolutely essential to follow the steps in strict order.
