I read that when a client switch in VTP is powered up it sends a summary advertisement from its own stored database and if a server switch with a lower revision number is connected to the client switch it will accept the advertisement as a more up-to-date information.
I tryed the following in my lab: I unppluged the trunk between client and server.The client switch has revision number 4. I reseted the revision number of the server switch to 0. Both have the same domain name and VTP password. I turned the client switch off. Connected the trunk (cable) between client and server. Turned client switch on....... the revision number in the server is still 0.... whay is it not getting the advertisement from the client and updates its database to revision number 4 (in this case)? Any light on the subject?
