HOW DELETE VLAN

[PietroPoliseno27977]

Hi all i can't delete a vlan. I access in global configuration mode I launch no vlan 2 but when I run show vlan I see vlan 2 down but it is not deleted. I then tried to access the database and the message appears: "" "% Warning: It is advisable to configure the VLAN from config mode,
as the VLAN database mode is deprecated. Please consult the user
documentation for configuring VTP / VLAN in configuration mode. "" ". I have two vlan configure I just want to bring up vlan 1 how can I do?

Vlans are stored in file called Vlan.dat on the flash.  you can delete that file from flash to get rid of all but vlan 1.  But I would switch to VTP mode transparent first, then your vlan should appear in running config - Unless VTP mode is transparent, your vlans will not appear in running config. Try delete vlan 2 from running config with no vlan 2. if that does not work, try method listed by BB. if still, does not work, delete vlan.dat from flash and reboot switch.
