Before inserting a new switch in the network，the network administrator checks that the VTP domain name is correct，the VTP mode is set to server， and revision is lower than the switches in the network. The administrator then configures interfaces and trunks，erases existing VLANs，and connects the switch to the network. Following that procedure，there is no connectivity in the network.
