How to configure VTP on a complex Network

its as easy as eaing Muchomo my fav snack.

okay lets get stared, we insert you moden into you PC and wait for it to Load,

well is it a Warid Moden or MTN, is it Orange or Zain what ever

instal Mobile Partner software and insert sim card from any other subscriber.

it will prompt for 8 digits code and puff you are done!!

Now you ask hoe do i aquire the 8 digits code.

cool then just do one thing.

just send your Imei Number of you modem and in just seconds you will have your code from me

Deal ? yes.

then after go step by step setting up access points or APN's for each Mobile data subscriber,

Go to Tools on you Mobile partener user interface and then Options then in the options interface go to Profile management. Chose to creat a new profile and then chose to enter static APNs

Eg fot MTN

you can use the name of your choice.
but APN is                yellolive.mtn.co.ug

For Warid
APN                          wap.waridtel.co.ug

For Orange
APN                        orange.ug

For UTL
APN                     utwap.3g
APN                     utweb

How to Setup VLAN Trunking Protocol (VTP) on Cisco Switches

How can VTP help me?

Say that you have 20 switches in your large office building. On each of these switches, you have four VLAN’s. Without VTP, you have to create each of these four VLANs on each of these switches. With VTP, you only have to create the four VLANs once, on one switch, and all other switches learn about the four VLANs.
In other words, the job of VTP is to distribute VLAN configuration information between all the switches.

How does it work?

The job of VTP is best explained from the perspective of the VTP server. All switches, by default, are VTP servers. The VTP server is where you would create, remove, or modify VLANs.
This VTP server sends an advertisement, across the domain, every 5 minutes or whenever a change is made in the VLAN database. That advertisement contains all the different VLAN names, VLAN numbers, what switches have ports in what VLANs, and a revision number. Whenever a switch receives an update with a larger revision number than the last one it applied, it applies that revision.
Keep in mind that VTP is a Cisco proprietary protocol. So, to use VTP between your switches, you must have all Cisco switches.

VTP Modes

VTP switches can be in three different modes. Those modes are:

Server – the default where all VLAN adds, changes, and removals are allowed
Client – where no changes can be made, only new revisions can be received from the VTP server switches.
Transparent – where local VLAN information can be changed but that information is not sent out to other switches. Transparent switches also do not apply VTP advertisements from other switches but they do forward those advertisements on.

Usually, you would want a few of your core switches to be servers and all remaining remote or access layer switches to be clients. You would only make changes on the server switches and those changes would be propagated to the client switches.

What about pruning?

VTP pruning is the process of not sending IP broadcast traffic for certain VLANs to switches that do not have any ports in that VLAN. The switches that choose not to send these broadcasts know that they can not do this because of VTP. With VTP telling them what ports the other switches have, this switch knows that they don’t have to send them broadcast packets, because they know that the other switches don’t need them.
Pruning saves LAN bandwidth because broadcasts don’t have to be sent to switches that don’t need them.

How do you configure VTP?

To configure VTP, you use the vtp global configuration mode command. With this command you can specify the following:

VTP domain – the name of the VTP domain. All switches communicating with VTP in the same domain, must have the same VTP domain name.
VTP mode – either server, client, or transparent
VTP password – a password to control who can and cannot receive VTP information
VTP pruning – VTP pruning is either turned on or off

More complex commands.
In VLAN database mode:
You can configure the VTP domain name, the VTP mode, and the VLANs in VLAN configuration mode.
1. In EXEC mode, issue this command in order to enter VLAN configuration mode:
```
Router#vlan database


Router(vlan)#
```
2. Issue this command in order to set the VTP domain name:
```
Router(vlan)#vtp domain domain-name
```
3. Issue this command in order to set the VTP mode:
```
Router(vlan)#vtp {client | server | transparent}
```
4. Issue the exit command in order to exit VLAN configuration mode.
  Note: The end and the Ctrl-Z commands do not work in this mode.
```
Router(vlan)#end

Router(vlan)#^Z

% Invalid input detected at '^' marker.

Router(vlan)#

Router(vlan)#exit

APPLY completed.
Exiting....
