5. Introduction to Local Area Network (LAN)
Characteristics of LAN
Easily resource sharing
Data transfer rate are high
Small area covered by LAN
Cost of setting up the network is usually low
Flexibility, low error rates and reliability of operation and
simple maintenance

9. Introduction to Local Area Network (LAN)
Problems in LAN
 To create group of users by department that work together instead of by
physical location is impossible in LAN
 Cannot reduce broadcast domain
 Cannot enforce security by group wise
 Overall performance is not good
 Impossible to design a network using more than 300 computers
 Need more Network administrators
 To increase the number of host is complex
 Maintenance cost is high

10. Introduction to Virtual Local Area Network (VLAN)
Defining VLAN
A Virtual Local Area Network (VLAN)is a group of devices that function as a single

Local Area Network segment (broadcast domain).

Collision domain and Broadcast domain

12. Introduction to Virtual Local Area Network (VLAN)
Types of VLAN connection Link
There are two types of VLAN connection links and they are Access
link and Trunk link-
Access Links/Ports: Access Ports: An access port belongs to
and carries the traffic of only one VLAN
Trunk Links/Ports: Trunk ports can carry multiple VLANs at
a time. A trunk link is 100 or 1000Mbps point-to-point link
between two switches, between a switch and router, or even
between a switch and server, and it carries the traffic of
multiple VLANs from 1 to 4094 at a time.

13. Introduction to Virtual Local Area Network (VLAN)
Establishing VLAN membership
The two common approaches to assigning VLAN membership
are as follows:
Static VLANs
Dynamic VLANs
Figure: Static VLAN Figure: Dynamic VLAN

14. Introduction to Virtual Local Area Network (VLAN)
Benefits of VLAN
Increased performance
 Improved manageability
 Simplification of software configurations
 Increased security options

15. Introduction to VLAN
Security Required in VLAN
The following security requires for a good VLAN:
Authentication
Access Control
Confidentiality
Integrity
Non repudiation

19. Implementation of VLAN
Modes of Router and Switch
User Mode
Privilege Mode
Config Mode
Example
Router> (user mode)
Router # (privilege mode)
Router(Config)# (Config Mode )

20. Implementation of VLAN
Ways of getting connection into User mode
Console: An RJ-45 connection on all Cisco routers allows full
access to the router if no passwords are set.
Aux: An RJ-45 connection on most routers allows to connect a
modem to the port, dial in to the router, and make a console
connection.
VTY: Virtual Teletype is used to allow a Telnet connection to
the router, which will then work like a console port. It must
have an active interface on the router for Telnet to connect to
the router.

21. Implementation of VLAN
VLAN configuration step by step
Router configuration
Switch configuration
 Host configuration

22. Implementation of VLAN
Router configuration
Figure: Router connection to PC
Rolled
Cable
To set the host name we use the following commands
Router>enable
Router#configure terminal
Router(config) #hostname GRouter
To set the password at the console port we use the following commands
GRouter(config)#line vty 0 4
GRouter(config-line)#login
GRouter(config-line)#password 123
GRouter(config-line)#exit
GRouter(config)#

23. Implementation of VLAN
To set the IP address and subnet mask by using the following commands
GRouter(config)# interface g0/1
GRouter(config-if)# ip address 172.16.1.1 255.255.255.0
GRouter(config-if)#duplex auto
GRouter(config-if)#speed auto
GRouter(config-if)# no shutdown
GRouter(config-if)# exit
GRouter(config)# ^z
GRouter# write
GRouter#disable
GRouter>
To configure the inter VLAN by using the following commands(This step should be done by telnet after all
the switches configure)
GRouter>enable
GRouter#
GRouter(config)#interface g0/1.3(creating sub interface)
GRouter(config-subif)#encapsulation dot1q 3(3 for VLAN 3)
GRouter(config-subif)#ip address 172.16.3.1 255.255.255.0
GRouter(config-subif)#no shutdown
GRouter(config-subif)#exit
GRouter(config)#interface g0/1.4
GRouter(config-subif)#encapsulation dot1q 4(4 for VLAN 4)
GRouter(config-subif)#ip address 172.16.4.1 255.255.255.0
GRouter(config-subif)#no shutdown
GRouter(config-subif)#exit
GRouter(config)#
GRouter(config)# ^z
GRouter# write
GRouter#

24. Implementation of VLAN
Switch configuration

Figure: Switch connection to PC
To set the host name we use the following commands
Switch>enable
Switch #config t
Switch-A(config) #hostname Switch-A
Switch-A (config) #
To set the password we use the following commands
Switch-A(config)#line vty 0 4
Switch-A(config-line)#login
Switch-A(config-line)#password 123
Switch-A (config-line)#exit
Switch-A (config)#

25. Implementation of VLAN
To set the IP address and subnet mask by using the following commands
Switch(config)# interface vlan 1
Switch-A(config-if)# ip address 172.16.1.2 255.255.255.0
Switch-A(config-if)# no shutdown
Switch-A(config-if)# exit
Switch-A (config)#
Switch-A(config)#ctrl+z
Switch-A#write
To configure the name of VLANs by using the following commands
Switch-A#config t
Switch-A(config)#vlan 3
Switch-A(config-vlan)#name Registrar
Switch-A(config)#exit
Switch-A(config)#vlan 4

26. Implementation of VLAN
To configure the ports by using the following commands
Switch-A #config t
Switch-A (config)#interface g1/1
Switch-A (config-if)# switchport mode trunk
Switch-A (config-if)#exit
Switch-A(config)#interface f0/1
Switch-A (config-if)# switchport trunk allowed vlan 1-20
Switch-A (config-if)# switchport mode trunk
Switch-A (config-if)# exit
Switch-A(config)#interface f0/2
Switch-A (config-if)# switchport trunk allowed vlan 1-20
Switch-A (config-if)# switchport mode trunk
Switch-A (config-if)# exit
Switch-A(config)#interface f0/6
Switch-A (config-if)# switchport access vlan 6
Switch-A (config-if)# exit
Switch-A(config)#interface f0/7
Switch-A (config-if)# switchport access vlan 7
Switch-A (config-if)# exit
Switch-A (config)#
Switch-A (config)# ctrl+z
Switch-A# write
Switch-A# disable
Switch-A>
