What is configuration revision number?

The configuration revision number is a 32-bit number that indicates the level of revision for a VTP packet. Each VTP device tracks the VTP configuration revision number that is assigned to it. Each time that you make a VLAN change in a VTP device, the configuration revision is incremented by one.

Can a VTP client update a server?

VTP clients and servers alike will accept VTP updates from other VTP server switches. When using VTP, for better availability, a switched network using VTP needs at least two VTP server switches.

Which VTP mode will not allow the switch to participate in VTP traffic but will forward VTP traffic?

Unlike VTP Server/Client, Transparent mode does not participate in the VTP domain at all however it transparent mode will pass VTP frame from one switch to the next.

What can you not do on a VTP client switch?

A VTP client behaves like a VTP server and transmits and receives VTP updates on its trunks, but you cannot create, change, or delete VLANs on a VTP client.

What is the importance of revision number in VTP?

The VLAN Trunking Protocol (VTP) revision number is important because it determines which updates are to be used when not managed properly this number can cause the deletion of all your networks VLAN information.

What are the 3 VTP modes?

VTP modes – There are 3 modes:

• Server – The switches are set to this mode by default.
• Client – In this mode, the switches receives the updates and can also forward the updates to other switches(which are in same VTP domain).
• Transparent – This mode only forwards the VTP summary advertisements through trunk link.

What is VTP client mode?

VTP Client mode Sends/forwards VTP advertisements and Synchronizes VLAN configuration information with other switches.

How do I change my VTP domain and password?

To set the password for the VTP administrative domain, use the vtp password command. To remove the administrative password, use the no form of this command.

In which VTP mode we can’t add and delete VLAN?

VTP client mode – a switch using this mode can’t change its VLAN configuration. That means that a VTP client switch cannot create or delete VLANs. However, received VTP updates are processed and forwarded. VTP server mode – a switch using this mode can create and delete VLANs.

Why VTP is not recommended?

VTP is generally not recommended anymore because of configuration complexity and the potential for catastrophic failure. In other words, a small mistake on the VTP configuration can take whole network down.

What is VTP configuration revision number and its importance in VTP operation?

The VLAN Trunking Protocol (VTP) revision number is important because it determines which updates are to be used when not managed properly this number can cause the deletion of all your networks VLAN information. Having all of your VLAN information deleted could be ruinous for your data network.

What is VTP pruning mode?

VTP pruning enhances network bandwidth use by reducing unnecessary flooded traffic, such as broadcast, multicast, and unicast packets. VTP pruning increases available bandwidth by restricting flooded traffic to those trunk links that the traffic must use to access the appropriate network devices.

How is the revision number of a VTP device changed?

Configuration Revision Number. Each time that you make a VLAN change in a VTP device, the configuration revision is incremented by one. In order to reset the configuration revision of a switch, change the VTP domain name, and then change the name back to the original name.

Is there a way to reset the revision number?

Below is the step by step method to be followed – This procedure is a faster method to clear the VTP configuration revision number. Here we change the switch VTP mode to “Transparent Mode”, and then switch back.

How to check VTP configuration number on Cisco switch?

show vtp status command on Cisco Switch in order to check the VTP configuration revision number. Go to the global configuration mode and change the VTP domain name on Cisco Switch. Again change the VTP domain name back to initial domain name.

When do you set a VTP domain name?

When you set a VTP Domain Name, the revision number is set to zero, after which each change to the VLAN database increases the revision number by one. When a switch receives VTP information from a neighboring switch, the first switch processes data only for the same domain when the revision number is higher than its own.
