Configuring basic VTP on CISCO SwitchesPosted on 7 September 2012 by Beaming Support
Instructions for configuring basic VTP on CISCO Switches
Requires: At least 2 x CISCO Switches
NB: This document requires a native and trunking VLAN between the switches in order for VTP to propagate across switches.
Step 1 – Creating a VTP Server
VTP has the following 3 different modes:
Server – Gives the switch the ability to create, modify and delete VLANs.
Client – This mode allows the switch assigned to participate in VTP and receive updates. You will not be able to create, modify or delete VLANs on a switch defined in Client mode.
Transparent – The assigned switch will ignore all VTP advertisements and you will be able to modify the switches VLANs
VTP Server Mode is set with the following commands in configuration mode :
vtp mode server (Sets the switch to server mode) vtp domain test (Defines the VTP domain, all switches in the domain will receive these VTP updates.) vtp password testpassword (Secures VTP advertisements to a matching domain and password)
Step 2 – Configuring a switch as a VTP client.
Enter configuration mode and use the following commands to enable client mode.
vtp mode client vtp domain test vtp password testpassword
Step 3 – Configure native and trunking VLAN.
Apply the following commands to the switchports that interconnect the switches.
interface range gigabit 0/0 switchport mode trunk no shutdown
Step 4 Testing VTP
Create the following test VLANS on the VTP server in configuration mode
vlan 15 name TESTLAN vlan 16 name WIRELESS exit
On the client switch check the VTP advertisement has propagated by entering the following command
show vlan brief
If VTP has been successful then you should expect to see the following results:
Show VLAN Brief: 15 TESTLAN active 16 WIRELSS active
Fibre Optic Leased Lines
A dedicated fibre optic Ethernet connection that’s just for you. Consistently speedy data transmission, easy scalability and symmetric upload & download speeds come as standard with a fibre optic leased line.
Fibre to the Premises (FTTP)
Sometimes known as “full fibre” or “pure fibre”, Fibre to the Premises (FTTP) connectivity is just as the name implies; data delivered all the way to your building through fibre optic cabling.
