I am confused about VTP, and I'm sure someone here can clear up my confusion.
Currently, most of our closet switches are set as VTP clients getting VLAN updates from our core switches (6500's). When I do a "show vlan" on the closet switch it will show the entire list of vlans that have been created on the core, which is what I would suspect. Now, on a couple of our closet switches we have enabled prunning on the core to only send the necesary vlans to that switch. Doing a show vlan proves that it works. When I change the closet switch to vtp transparent, the vlans still show up when a show vlan is requested. Also, I recently added a vlan to the 6500's that I wanted propagted to the closet switches, thinking that the transparent mode switches would not recieve that vlan update, but they did. So, basically I am looking for an explanation of why transparent mode would update it's vlan database from a root switch. Isn't it true that a transparent switch will only add locally created vlans and ignore all other vtp updates? ANy help is appreciated.
