This read-create object stages writable extended type-information bits for a VLAN in the edit buffer, following the VlanTypeExt textual convention that defines exactly which bits a management application is allowed to set, with the agent supplying sensible defaults. An administrator would set specific extended-type bits here when a staged VLAN needs particular extended attributes not covered by the basic type field. For example, an admin enabling a specific extended VLAN behavior would flip the appropriate bit in vtpVlanEditTypeExt2 before applying the edit buffer.
