Chapter 14 Configuring VTP
Configuring VTP
VTP Version
Follow these guidelines when deciding which VTP version to implement:
• All switches in a VTP domain must run the same VTP version.
• A VTP Version 2-capable switch can operate in the same VTP domain as a switch running VTP
Version 1 if Version 2 is disabled on the Version 2-capable switch (Version 2 is disabled by default).
• Do not enable VTP Version 2 on a switch unless all of the switches in the same VTP domain are
Version-2-capable. When you enable Version 2 on a switch, all of the Version-2-capable switches
in the domain enable Version 2. If there is a Version 1-only switch, it does not exchange VTP
information with switches that have Version 2 enabled.
• If there are TrBRF and TrCRF Token Ring networks in your environment, you must enable VTP
Version 2 for Token Ring VLAN switching to function properly. To run Token Ring and Token
Ring-Net, disable VTP Version 2.
Configuration Requirements
When you configure VTP, you must configure a trunk port on the switch or switch stack so that the
switch can send and receive VTP advertisements to and from other switches in the domain.
For more information, see the “Configuring VLAN Trunks” section on page 13-16 .
If you are configuring extended-range VLANs on the switch, the switch must be in VTP transparent
mode.
VTP does not support private VLANs. If you configure private VLANs, the switch must be in VTP
transparent mode. When private VLANs are configured on the switch, do not change the VTP mode from
transparent to client or server mode.
Configuring a VTP Server
When a switch is in VTP server mode, you can change the VLAN configuration and have it propagated
throughout the network.
Note If extended-range VLANs are configured on the switch, you cannot change VTP mode to server. You
receive an error message, and the configuration is not allowed.
Beginning in privileged EXEC mode, follow these steps to configure the switch as a VTP server:
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 vtp mode server Configure the switch for VTP server mode (the default).
Step 3 vtp domain domain-name Configure the VTP administrative-domain name. The name can be 1 to 32
characters. All switches operating in VTP server or client mode under the
same administrative responsibility must be configured with the same
domain name.
