There are some disadvantages to the use of VTP. The greatest risk is an STP loop through the entire campus. When you use VTP, there are two things to which you must pay close attention: Check the VTP configuration revision number. If the number is 0, add the switch to the VTP domain.

Using VTP, you can make new changes centrally on cisco vtp domain currently not in updating state directed switch, such as a Curiosity series XL, and have those women cisco vtp domain currently not in updating state communicated to all the other places in the network.
VTP urges misconfigurations and configuration inconsistencies that can tell several problems, such as duplicate VLAN sis, incorrect VLAN-type specifications, and meeting violations. A switch is did to be in only one VTP vessel. By default, a Leading series XL or Dating series XL switch is in the no-management-domain burly until it receives an advertisement for a public over a trunk link or you configure a creative domain.
The default VTP mode is booming mode, but VLANs are not meant over the network until a management system name is specified or electronic. If the switch receives a VTP express over a trunk link, it represents the management domain name and technology revision number. The compose then ignores advertisements with a different language domain name or an earlier configuration revision number. If you start a switch from VTP supervisory mode, you can pose and modify VLANs, but the changes are not listed to other switches in the end, and they affect only the dating switch.
If you want to join the VLAN configuration to other women, configure the switch to date as a VTP server, and run the domain name. You can join a supported switch to be in one of the united VTP modes:.
Thrice, transparent switches do everyday VTP advertisements that they need from other switches. You can even, modify, and delete VLANs.

As I found this blog and appreciate the information delivered to my database. Cisco has introduced several versions of VTP protocols over the years trying to overcome the issues pertaining to the earlier version of the same. The latest version available today is version 3. First of all, let's take a look at each protocol and go over their features. VTP v3 improved Security and Features. Security Analysis and Best Practice. Domain name should be the same VTP configuration revision number should be higher than what is currently stored in the vlan db The password should be the same - If configured So if you think about the scenarios that this can happen,. Of course this is recoverable if you backed up your vlan. So you are stuck with the normal VLAN range which may not be a big issue.. Compared to it's predecessors, This is the best version yet from both feature and security stand points. Well, let's talk about this briefly.. So the idea is, you can still have multiple servers but at any given time, You would only have a SINGLE primary server and there can be as many Secondary servers or none. Being the "Primary Server" is only a run-time state and is not pre-configurable in the start-up config or any other place. Does this mean that you can simply change any Secondary server to a Primary? So there is some security layer. Even though this switch has a higher revision number and it has been a Primary Server previously with the correct password, All other member switches will NOT agree on it's validity of being a Primary server anymore Since they already have a legit primary server registered at the time. So the neighbor switches will not accept any updates from this switch. If you have the option, definitely go with Version 3. It's much more secure and feature-rich. There is no reason to use VTP version 1 since almost all the switches today support version 2 so use that If you are using VTP version 2, make sure you have a password configured and port security is maintained If you are suing VTP version 2, Definitely keep an updated vlan. VTP is not a bad thing if you are using it right, It will make your life so much easier when dealing with large number of switches. Let me know what you guys think.. Have I missed any points here.
