How to create VLANs? VLAN Tutorial

Configuring VLANs and Assigning VLANs to interfaces

SW1# configure terminal

SW1# vlan2

SW2# name Sales department

SW2# exit

SW2# interface range fastethernet 0/11 – 16

SW2# switchport access vlan2

SW2# switchport mode access

SW2# end

In the above configuration, SW1 is the switch name. ‘#’ denotes privileged EXEC mode or enable mode.

1.       “Configure terminal” command: This command is used to enter into Global configuration mode.

2.       “vlan2” command: This command is used to create a vlan.

3.       “name Sales department#: This command is used to give a name to vlan2 as Sales department. If you don’t want to give a name, this command can be ignored.

4.       “exit” command: To exit to privileged EXEC mode.

5.       “interface range fastethernet 0/11 – 16: To enter into interface configuration mode to configure the switch interfaces from 11, 12, 13, 14, 15 & 16.

6.       “switchport access vlan2” command: To specify the VLAN number associated with the above interfaces.

7.       “switchport mode access” command: To make this interface range 11 to 16 to always operate in access mode (that is, to not trunk).

You can learn the different types of switchport mode here.

8.       “end”: This command is used to get back to privileged EXEC mode regardless of what configuration mode or configuration sub mode you are in.
