Abstract
A method of automatic discovery of existing Virtual Local Area Network (VLAN) configuration in a bridged network is provided. The method includes steps of: reconciling a data transport infrastructure in a data transport network; reconciling data transport node configurations; gathering nodal VLAN configurations from all data transport nodes; correlating the data transport infrastructure information, node configuration information and nodal VLAN configurations; and extracting network-wide provisioned VLAN configuration subject to discrepancies. A VLAN auto-discovery application tool having human-machine interface is also provided. The VLAN auto-discovery application tool is operable to initiate the VLAN auto-discovery process and to display the discovered VLAN configuration. The VLAN auto-discovery human-machine interface also is adapted to display a VLAN-specific provisioning status. Advantages are derived from a centralized VLAN auto-discovery solution which reduces VLAN provisioning overheads, enables fast recovery from Network Management System (NMS) failures, reduces recovery times from network wide failures, etc.
