Hello everyone,

I have a 3550 < IPBASEK9-M > running version 12.2<40>SE software.

There is a VTP domain name setup on the switch.

I am using the Transparant mode on the switch.

I also have created an extended vlan.

How do I remove the VTP domain name.  I do not want a name configured on the switch.

Thanks for your help,

Matt

Hi Matt,

The default domain is null in vtp mode,Note once you've changed a switch's VTP domain to something other than null,there is no way to change it back to null short of erasing the configuration and rebooting.

Hope to Help !!

Hi All,

It's quite simple

Write erase

Delete flash:vlan.dat

reboot and your switch is in factory default.

The vlan.dat file is recreated.

You can now upload your cleaned config again and recreate the vlan's (make a backup before you do anything;-)

Best regards,

Robert

Please if you don't know the answer don't answer your answer can cause a big problem if someone take it seriously. There is a difference between removing VTP domain name and clearing the switch configuration/vlan.dat. I am sure you know what is the difference I just don't know why you answer that way. 

Have a good life

I encountered the same issue and the resolution for removing the VTP Domain for Catalyst 4500 switches is 

 " erase cat4000_flash: " then reload your switch. Your Domain name will be removed. 

 

Note 1-  This should be used when you don't find Vlan.dat file in your flash 

Note 2 - This will erase all your config both startup and running cofig.

 

Your answer solved my same problem, thank you

Hello.

 

Maybe the fast way is try this:

 

#dir flash:

3 -rwx 1120 Mar 1 1993 08:28:41 +00:00 vlan.dat

#rename flash:vlan.dat flash:vlan_OLD.dat

Destination filename [vlan_OLD.dat]? [press ENTER]

to confirm: #dir flash:

399 -rwx 1516 Jan 2 2006 04:24:07 +00:00 vlan_OLD.dat

#wr or copy run start

#reload
Proceed with reload? [confirm] [press ENTER]

after reloaded

VTP Domain Name :

 

Bye!!!
