sorry i have also posted under security by misake!
I am planning to change VTP mode from server to transparent on 2 switches linked via L3. The switches also have indirect layer 2 link via trunking between 2 other switches! (sorry no diagram). VTP advertisment is via that vlan 2. Both switches exchanging vtp advertisement via vlan 2.
Both switches also have trunking with DTP enable to other switches. My concern is chanding vtp to transparent and that affecting DTP on trunk ports to other directly connected switches!!!. i know trunking is needed for VTP but not sure if changing vtp will affect DTP!! I'm not it doesnt but the switches are in production!
