How do I delete a VTP domain from a 6509 running IOS?

[jkeeffe]

I want to get rid of a VTP domain out of this box but can't find the command to do it. Here is the config:

vtp domain ENGLAB

vtp mode transparent

ENGLAB-6513-Native#sh vtp status

VTP Version : 2

Configuration Revision : 0

Maximum VLANs supported locally : 1005

Number of existing VLANs : 7

VTP Operating Mode : Transparent

VTP Domain Name : ENGLAB

VTP Pruning Mode : Disabled

VTP V2 Mode : Disabled

VTP Traps Generation : Disabled

I want to be able to connect a 4506 switch to this 6509 on the same layer 2 network and not have to have a VTP domain control access.

So is there a way to just plain remove the VTP configuration from the 6509?

You can change the vtp domain string to a null value with the command:

vtp domain ""

here's an example from a lab switch:

6k-native#show vtp status

VTP Version : 2

Configuration Revision : 0

Maximum VLANs supported locally : 1005

Number of existing VLANs : 30

VTP Operating Mode : Transparent

VTP Domain Name : blah

VTP Pruning Mode : Disabled

VTP V2 Mode : Disabled

VTP Traps Generation : Disabled

MD5 digest : 0x45 0xE2 0xD5 0x74 0x96 0x79 0x35 0xD6

6k-native#conf t

6k-native(config)#vtp domain ""

Changing VTP domain name from blah to

6k-native#show vtp status

VTP Version : 2

Configuration Revision : 0

Maximum VLANs supported locally : 1005

Number of existing VLANs : 30

VTP Operating Mode : Transparent

VTP Domain Name :

VTP Pruning Mode : Disabled

VTP V2 Mode : Disabled

VTP Traps Generation : Disabled

MD5 digest : 0xE8 0x53 0x9D 0x00 0x12 0x20 0xCA 0xD6

6k-native#

Note that if you use the command

vtp domain NULL, you'll simply change the vtp domain name to the string 'NULL' rather than assinging it a NULL value.

HTH,
