Hi Guy's

Another sharing of knowledge =)

How among you had configure a cisco switch?
I have some configurations here that might help you.

let's start with trunk protocol
trunk is used when your port you want to have a connection with the router with a vlan

for example you want to have a trunk port on fast ethernet 0/1
here's the config
on your switch type:

Switch(config)#int fa 0/1
Switch(config-if)#switchport mode trunk - this command is enabling your port to serve as a trunk port
Switch(config-if)#switchport trunk allowed vlan all - this command is allowing all vlans to travel in this port to the router

Creating Vlan:

VLAN is a virtual Local Area Network
this is used to seperate or create a network in just one switch

steps to create VLAN

Switch(config)#vlan 10 - this command enable to create the vlan followed by a number 10 which means the vlan you created is for vlan 10
Switch(config-vlan)#Name Sampleforbubblews - this command is allowing you to have a name of the VLAN 10

then next is allowing a port to be at VLAN 10

Switch(config)#int fa0/2 - first you will enter the port that you want to be in vlan 10
Switch(config-if)#switchport mode access - this is to start the port to be an access port
Switch(config-if)#switchport access vlan 10 - this command will state that this specific port will be on vlan 10

I Think this will help you on your cisco switch to create a vlan and a trunk
have a nice day guys and keep buzzing =)
