I am trying to configure pvlans on 2 6500 switches. I cannot perform any pvlans unless the switches are in vtp transparent mode. My switches which total 4 are configured with one vtp server and 3 vtp clients in one vtp domain. I would rather not make such a drastic change for a new backup network. I want to add security not take away some central managment capabilities. Does any one know a work around? Why cant a vtp server perform pvlans? Thanks in advance.
