When you delete a VLAN from a switch that is in VTP transparent mode, the VLAN is deleted only on that specific switch. You cannot delete the default VLANs for the different media types: Ethernet VLAN 1 and FDDI or Token Ring VLANs 1002 to 1005. To delete a VLAN from the database, use the following commands beginning in privileged EXEC mode: Cisco IOS Release 12.2(2)XT, 12.2(8)T, and 12.2(15)ZJ 53
