the physical locations of the users. VLANs have the same attributes as physical LANs, but you can group end stations
even if they are not physically located on the same LAN segment.

2 ways to Configure VLANs

A. VLAN Configuration Mode Way
supported by newer cisco switches
exam
syntax:
conf t
vlan 10
name IT
exit

B. Vlan Database Mode Way

enable
vlan database
vlan 10 name IT
exit

In this lab, will use the vlan configuration mode way ...

conf t
vlan 10
name IT
exit

conf t
int fa0/4
switchport mode access
switchport access vlan 10 //assign single int to Vlan
exit

conf t
int range fa0/4-fa0/8
switchport mode access
switchport access vlan 10 //assign a range of interfaces to Vlan
exit
