Basic Vlans and Trunks Part 1

                  Basic Vlans and Trunks Part 1

1.      Take two systems and one switch. (Change system name as LAB and another one as Student)

3.      Connect two systems to switch through Straight cable.

4.      Connect (System) LAB to switch port 5.

5.      Connect another (system) Student to switch port 6.

6.      Configure both system IP as (192.168.1.100    192.168.1.101).

7.      Now try to ping from one system to another.

8.      Now we need to configure vlans.

9.      Single click on switch and select CLI (IOS command line interface).

        Switch>

       Switch >enable

       Switch#config terminal

       Switch (config) # vlan 50

       Switch (config –vlan)#name student    ( Now vlan 50 has changed to vlan Student)

       Switch (config –vlan)#vlan 99

       Switch (config –vlan)#name LAB           (Now vlan 99 has changed to vlan LAB)

       Switch (config –vlan)#exit

       Switch (config)#exit

       Switch#        (Vlans are modified)

       Change switch fastethernet ports to vlans according to our systems.

       Switch# configure terminal

       Switch (config) # interface fastEthernet 0/5

       Switch (config-if)# switchport mode access

       Switch (config-if)# switchport access vlan 50

       Switch (config-if)# exit

       Switch# configure terminal

       Switch (config) # interface fastEthernet 0/6

       Switch (config-if)# switchport mode access

       Switch (config-if)# switchport access vlan 99.

       Switch (config-if)# exit

       Switch#

10.   Now try to ping from one computer to another computer, it will show Request time out

But both systems can access internet. Both are in different vlans in same switch.

If any clarification please mail to ccnalab06@gmail.com   (Zerosix)

     

Types of VLAN

There are different types of VLANs. The type of network traffic they carry defines a particular type of VLAN and others derive their

names due to the type or a specific function the VLAN performs. The following describes common VLAN:

Default VLAN

At the initial boot up of the switch, All switch ports become a member of the default VLAN, which makes them all part of the same broadcast domain. This allows any network device connected to any of the switch port to communicate with other devices on other switch ports.

On Cisco switches the default VLAN is VLAN 1. VLAN 1 has all the features of any VLAN, except that you cannot rename or delete it.

Data VLAN

A data VLAN that can also be referred to as user VLAN. This is configured to carry only user-generated traffic. The importance of separating user data from other type of VLAN is proper switch management and control.

Native VLAN

A native VLAN is assigned to an 802.1Q trunk port. An 802.1Q trunk port supports traffic coming from many VLANs as well as traffic that do not come from a VLAN. The 802.1Q trunk port places untagged traffic (traffic that does not come from a VLAN) on the native VLAN. In summary, the native VLAN observes and identifies traffic coming from each end of a trunk link.

Management VLAN

A management VLAN is any VLAN you configure to access the management capabilities of a switch. Your configured management VLAN is to be assign with an IP address and subnet mask. Any of a switch VLAN could be configured as the management VLAN if you has not configured or define a unique VLAN to serve as the management VLAN. In some cases, a network administrator proactively defines VLAN 1 as the management VLAN; this enables a loophole for an unauthorized connection to a switch.

Voice VLAN

Voice VLAN is configured to carry voice traffic. Voice VLANs are mostly given transmission priority over other types of network traffic. Communication over the network is not complete without phone calls. More calls are made over the network than other forms of s message transmission. Sending emails and text messages are also forms of inter-relations but listening to a real voice provides legitimacy and assurance.

It is considered among network administrators to design a network that support VoIP with an assured bandwidth to ensure voice quality, and capability to be routed around congested areas on the network with minimal delays (150-180 milliseconds).

In next post we will see each VLAN in practicals.

Step by step

1.       Take seven systems and 2 hubs 1 switch.

2.       Add four systems to one hub and remaining three to another hub as shown in above image

3.       Add two hubs to one switch.

4.       Add IP address to system Ex ( 192.168.1.0  to 192.168.1.7)

5.       Now ping from PC1 to PC6 and check.
