Continuing previous post with title VLAN-Switch, now I will talk about VLAN-Switches.

This topology of VLAN is needed a Trunk. What is a Trunk ?

Trunk is a physical connection between switch to switch or switch to router or between switch to pc with a special NIC supported Trunk.

The figure below is talking about Trunk between two switch. In this topology, Trunk is  functioning as a bridge for each VLANs. So VLAN 10 in switch-A can communicate to VLAN 10 in switch-B with a logical connection inside the Trunk. Similar explanation for VLAN 20. But remember, different VLAN still can not connected to each other.

Two switches, switch-A and switch-B. Each has two VLANs, VLAN 10 and VLAN 20.

In switch-A VLAN 10 registered on ethernet-port 0/1, while ethernet-port 0/2 has VLAN 20. And switch-B has VLAN 10 registered on ethernet-port 0/1, and ethernet-port 0/2 has VLAN 20. 

As usual we will setup the default configuration on the switch, like hostname, password, IP Address, and the VLAN itself. 

console:

switch-A: 

switch> enable

switch# conf t

switch(config)# hostname switch-A

switch-A(config)# enable password level 15 cisco

switch-A(config)# ip address 192.168.1.11 255.255.255.0

switch-A(config)# vlan 10 name Group-A

switch-A(config)# vlan 20 name Group-B

switch-A(config)# int fa0/26

switch-A(config-if)# trunk on

switch-A(config-if)# exit

switch-A(config)# int e0/1

switch-A(config-if)# vlan-membership static 10

switch-A(config-if)# exit

switch-A(config)# int e0/2

switch-A(config-if)# vlan-membership static 20

switch-B:

switch> enable

switch# conf t

switch(config)# hostname switch-B

switch(config)# enable password level 15 cisco

switch(config)# ip address 192.168.1.12 255.255.255.0

switch(config)# vlan 10 name Group-A

switch(config)# vlan 20 name Group-B

switch(config)# int fa0/26

switch(config-if)# trunk on

switch(config-if)# exit

switch(config)# int e0/1

switch(config-if)# vlan-membership static 10

switch(config-if)# exit

switch(config)# int e0/2

switch(config-if)# vlan-membership static 20
