Enabling VTP Pruning
To enable VTP pruning in the management domain, perform this task:
This example shows one way to enable VTP pruning in the management domain:
Switch# configure terminal
Switch(config)# vtp pruning
Pruning switched ON
This example shows how to enable VTP pruning in the management domain with any release:
Switch# vtp pruning
Pruning switched ON
This example shows how to verify the configuration:
Switch# show vtp status | include Pruning
VTP Pruning Mode: Enabled
Switch#
For information about configuring prune eligibility, see the “Understanding VTP Pruning” section on
page 17-10.
Enabling the VTP Version Number
VTP version 2 is disabled by default on VTP version-2-capable network devices. When you enable VTP
version 2 on a network device, every VTP version-2-capable network device in the VTP domain enables
version 2.
Caution VTP version 1 and VTP version 2 are not interoperable on network devices in the same VTP domain.
Every network device in the VTP domain must use the same VTP version. Do not enable VTP version 2
unless every network device in the VTP domain supports version 2.
Note In a Token Ring environment, you must enable VTP version 2 or VTP version 3 for Token Ring VLAN
switching to function properly on devices that support Token Ring interfaces.
To enable the VTP version, perform this task:
Command Purpose
Step 1
Switch(config)# vtp pruning
Enables VTP pruning in the management domain.
Step 2
Switch# show vtp status | include pruning
(Optional) Verifies the configuration.
Command Purpose
Step 1
Switch(config)# vtp version {1 | 2 | 3}
Enables the VTP version.
Step 2
Switch# show vtp status | include {v1 | v2 | v3}
(Optional) Verifies the configuration.
