I have around 40 L2 switches IOS v12.0-12.2 (2960, 3560, 3500, 3750) running in VTP client mode and one L3 switch CatOS v6.3(5) (6500) running in VTP server mode, all connected together. I would like to switch everything in VTP transparent mode without any interruption of service.
I've already test on a poc version with 3 switches (Catalyst 2950, 3560 and 3750). Using serial and SSH connection, it is seems working but i'm not sure it is enough representative compare to the real network.
Knowing that the VTP Pruning is enabled, I am wondering what would be the best procedure to proceed the changement. I've read that we could lost connection by keeping it enabled.
- Should I change the server or clients first?
- Is it important to change the VTP domain and VTP Pruning parameters?
