Cisco CCNA Certification Exam Tutorial: Configuring and Troubleshooting VTP

Not only is your CCNA exam questions on VLAN trunking protocol, almost all networks, to go more than one VLAN VTP stressed. Whether you are for passing the CCNA exam or simply improve your networking skills in design, this VTP tutorial will help you learn the basics of this important protocol.

VTP allows switches to advertise VLAN information between other members of the same VTP domain. VTP allows a consistent view of the switched network throughall switches. When you create a VLAN on a switch in a VTP server, all other devices in the VTP domain for VLAN that reported their existence. VTP servers will know about each VLAN, VLAN, and no members that have the switch.

VTP switches in a run of three modes. In server mode, VLANs can be created, modified and deleted on a VTP server. If these measures are adopted, the changes to all switches in the VTP domain are advertised. The server VTP VLAN configuration information maintainedreboot.

In client mode switch can not create, modify, or delete VLANs. Can not keep Client VTP VLAN configuration information to the restart, I get this information from a VTP server.

Networks in the real world, this is usually done to centralize the creation and deletion of VLANs. An interesting side effect of client / server approach is that if a VLAN is only change for the client ports on the VTP, VLAN must still firstbe created on the VTP server. The VTP client-server, you experience the VLAN from the VTP and VLAN ports can be placed so that

The third mode is a VTP transparent mode. VTP switches to ignore VTP messages. Would you like to receive VTP advertisements from other switches. VLANs can be created, deleted and edited on a transparent server, but these changes are not advertised to other switches in the VTP domain.

For switches running VTP onsuccessfully exchange VLAN information, three things must happen. I have listed for you in the order we see them in the real world.

The VTP domain name must match. This is case-sensitive. "Cisco" and "Cisco" are two different domains.

To distribute information about a new VLAN, the switch to which VLAN must be set in server mode.

Learning VTP is not only a good idea to pass the CCNA exam, is a skill that is requiredto be effective in configuring and troubleshooting VLANs. I wish you the best in both jobs!
