vtp (VLAN configuration)
• Domain names are case sensitive.
• After you configure a domain name, it cannot be removed. You can reassign it only to a different
domain.
Follow these guidelines when configuring a VTP password:
• Passwords are case sensitive. Passwords should match on all switches in the same domain.
• When the no vtp password form of the command is used, the switch returns to the no-password
state.
Follow these guidelines when enabling VTP pruning:
• If you enable pruning on the VTP server, it is enabled for the entire management domain.
• Only VLANs included in the pruning-eligible list can be pruned.
• Pruning is supported with VTP Version 1 and Version 2.
Follow these guidelines when enabling VTP Version 2 (v2-mode):
• Toggling the version (v2-mode) state modifies certain parameters of certain default VLANs.
• Each VTP switch automatically detects the capabilities of all the other VTP devices. To use VTP
Version 2, all VTP switches in the network must support Version 2; otherwise, you must configure
them to operate in VTP Version 1 (no vtp v2-mode).
• If all switches in a domain are VTP Version 2-capable, you need only to enable VTP Version 2 on
one switch; the version number is then propagated to the other Version-2 capable switches in the
VTP domain.
• If you are using VTP in a Token Ring environment or configuring a Token Ring bridge relay function
(TrBRF) or Token Ring concentrator relay function (TrCRF) VLAN media type, VTP Version 2
(v2-mode) must be enabled.
• If you are configuring a Token Ring or Token Ring-NET VLAN media type, you must use VTP
Version 1.
Examples This example shows how to place the switch in VTP transparent mode:
Switch(vlan)# vtp transparent
Setting device to VTP TRANSPARENT mode.
This example shows how to set the administrative domain for the switch:
Switch(vlan)# vtp domain OurDomainName
Changing VTP domain name from cisco to OurDomainName
This example shows how to configure the VTP domain password:
Switch(vlan)# vtp password private
Setting device VLAN database password to private.
This example shows how to enable pruning in the proposed new VLAN database:
Switch(vlan)# vtp pruning
Pruning switched ON
This example shows how to enable v2 mode in the proposed new VLAN database:
Switch(vlan)# vtp v2-mode
V2 mode enabled.
You can verify your settings by entering the show vtp status privileged EXEC command.
