VTP change from server mode to transparent mode

[ivanka_busta]

Hi,

We have a VTP domain in which all switches are in transparent mode. However, several have the wrong domain name or mode. As a result, some errors are being displayed in the log. I would like to change the VTP configuration in those switches. They are all in a production network. Which would be the best way to do it without causing problems to the network?

Regarding the switches which are in mode server and have a wrong domain name, should I change firstly the mode to transparent and then the domain name? Is there any risk of losing the vlan configuration?

Thanks in advance.

You write, all switches are in transparent mode, but also regarding those in server mode - i.e. which is it?

"Safest" would be to switch a server (or client) mode switch to transparent before changing domain name.  If you switch domain name first, yes you expose having shared VLAN information changed.

Thanks a lot. Now I have more clear the order in which I have to change settings.

All switches must be in transparent mode in the same domain. The problem is that there are a few which are in different mode and/or domain. The goal is to have all of them in the same domain in transparent mode.

BTW, I wonder about you (?) rating my response as a "2", that's not really a "thanks a lot" rating; just the opposite.  (I'm mentioning this because, at lease on my browser, ranking popups just list numbers and you might think lower is better.)
