How do I change my VTP revision number?

How do I change my VTP revision number?

PROCEDURE 2

1. Step 1 – Issue show vtp status command on Cisco Switch in order to check the VTP configuration revision number.
2. Step 2 – Go to the global configuration mode and change the VTP mode to ‘Transparent’ on Cisco Switch.
3. Step 3 – Again change the VTP mode from ‘Transparent’ to ‘Server’.
4. Step 4 –

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.

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 is revision number in VTP?

The configuration revision number is a 32-bit number that indicates the level of revision for a VTP packet. This configuration number is tracked by every switch in order to find that the received information is more recent than the current version.

What is VTP client mode?

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

What is VTP pruning mode?

VTP Pruning is about forwarding *** traffic over a trunk link only if the switch on the receiving end of the trunk link has ports in the source VLAN. This reduces the volume of flooded traffic. Manual Pruning is specifying which VLANs are allowed on the trunk.

Why we use servers and clients in VTP?

VTP Server Mode VTP Server can add, modify, and delete VLANs. It will propagate a VTP message containing all the changes from all of its trunk ports. If server receives a VTP message, it will incorporate the change and forward the message from all remaining trunk ports.

Which VLANs are allowed on a trunk link by default?

VLANs 1 through 1005 are allowed on each trunk by default. However, VLAN traffic can be removed from the allowed list. This keeps traffic from the VLANs from passing over the trunk link. Note: The allowed VLAN list on both the ends of the trunk link should be the same.

What is difference between VTP version 1 and 2?

In VTP V1, the only time a transparent mode switch will forward advertisements is when the version and domain name match (highly unlikely). In VTP v2, advertisements are forwarded regardless of the version number.

What is the revision number on a VTP server?

Each device tracks the VTP configuration revision number that is assigned to it. This information is used in order to determine whether the received information is more recent than the current version. Each time you make a VLAN change on a VTP server, the configuration revision number is incremented by one and a VTP advertisement is sent.

What happens when a switch receives a VTP packet?

The switch that receives a VTP packet compares the configuration revision to its own revision. If the configuration revision number in the received VTP advertisement is higher than its own revision number, the switch will overwrite its VLAN configurations with the new information that is being advertised.

How can I find out what my VTP configuration is?

To display the VTP configuration information, we can use the show vtp status command: The most important field listed in the output above is the Configuration Revision number. This number indicates the level of revision for a VTP packet. Each device tracks the VTP configuration revision number that is assigned to it.

Is the VLAN database revision number overwritten?

Yes, that’s right; even if the switch is a VTP client, if it has the same VTP domain name and a higher VLAN database configuration revision number, the existing VLAN database is overwritten. 09-13-2006 01:50 AM 09-13-2006 01:50 AM
