Configuring a VTP Management Domain
Before a switch is added into a network, the VTP management domain should be identified. If this switch is the first one on the network, the management domain will need to be created. Otherwise, the switch may have to join an existing management domain with other existing switches.
The following command can be used to assign a switch to a management domain on an IOS-based switch:
Switch# vlan database
Switch(vlan)# vtp domain domain_name
To assign a switch to a management domain on a CLI-based switch, use the following command:
Switch(enable) set vtp [ domain domain_name ]
