The invention discloses a method for managing information of a virtual local area network, which comprises that: a network management system establishes a virtual local area network VLAN summery table of a network element, a VLAN list of the network element is stored in the VLAN summery table, and ID of a VLAN established by a corresponding network element is recorded in the VLAN list; and the network management system establishes a VLAN configuration table, VLAN configuration information of non-defaults belonging to the VLAN established by the network element is stored in the VLAN configuration table, and the VLAN which doses not store the VLAN configuration information of the non-defaults in the VLAN configuration table adopts VLAN configuration information of defaults. The method improves a database storage table, and cancels storage defaults so as to solve the problems of large data redundancy, slow running speed of the system and the like in the VLAN information management in theprior art, can reduce data quantity stored in a database to an order of magnitude of 100,000, greatly improves corresponding speed of the system, and enables users to have carefree operation experience.
