VLANs: VTP Configuration Options

Domain

This configuration option for VTP sets the domain name.  VTP messgaes received by VTP neighbors are ignored unless the domain name in the message matches what is configured on the switch.

Password

This configuration option for VTP sets a password so unauthorized switches are unable to join the VTP domain.

Mode

This configuration option sets the role of the switch to either Server, Client, or Transparent.  In VTPv3 you can also set this to off, disabling VTP on the switch.

Pruning

This configuration option allows VTP pruning which prevents flooding on a per VLAN basis to switches that have no ports participating in a specific VLAN.

Interface

This configuration option defines which IP address is used to identify the switch as an updater in the VTP update messages.  By default a configured IP with the lowest numbered VLAN SVI is used.
