VTP defaults on 2950

I was hoping someone could make sure I've got some defaults straight for 2950/2960 switches with the latest IOS.

-will trunk out of the box with another 2950 or 2960 because the ports are set to dynamic desirable
-Will come up as a VTP server and update VLAN info on other 2950 switches that also have no domain name. Will assume domain name of first vtp message it receives from another switch.

-Out of box will not trunk to another new OOB 2960 because ports are set to dynamic auto.
-OOB comes up as a VTP server but will not update other switches or take updates until a domain name is set manually.

    The 2950s as you say are going to trunk with another switch that has either dynamic desirable, dynamic auto, trunking on because by default they are set to dynamic desirable. I can't speak of the 2960s because I haven't touched one... I think the most important part of your studies for this one is to understand the difference between dynamic auto, dynamic desirable, and DTP messages. I don't think I'm violating the NDA on this one... Cisco will not ask specifically about a switch platform because they know their technologies vary by platform! The same applies to the VTP... just be sure you understand the differences between VTP version 1 & 2. HTH...
