Abstract

An apparatus and method for transferring information in bulk between network devices employing File Transfer Protocol (“FTP”) are disclosed. During a network discovery process, an Element Management System (“EMS”) initiates a file generation command formatted with Simple Network Management Protocol (“SNMP”) to one or more network element (“NE”). After obtaining configuration information from one or more network devices, an NE, in one embodiment, establishes a file containing the configuration information and subsequently stores the file in a storage location. The file formatted in SNMP format is forwarded to EMS suing FTP/SFTP (secure file transfer protocol)/TFTP (trivial file transport protocol).
