Patent number: 9246849Abstract: A technique is provided for facilitating fabric membership login for an N_Port of a storage area network. A communication from a network node is received. The communication may include a portion of criteria associated with the N_Port. Using at least a portion of the portion of criteria, a virtual fabric identifier corresponding to a virtual fabric which is associated with the N_Port may be automatically identified. Fabric configuration information, which includes the virtual fabric identifier, may be automatically provided to the network node. A fabric login request from the N_Port to login to the virtual fabric may then be received. According to a specific embodiment, the communication may be transmitted from a network node to an F_Port on a Fibre Channel switch.Type: GrantFiled: October 6, 2014Date of Patent: January 26, 2016Assignee: Cisco Technology, Inc.Inventors: Gaurav Rastogi, Ramsundar Janakiraman, Kalyan Ghosh, Badri Ramaswamy, Joy J.

Patent number: 7843916Abstract: The Switch includes a port configured to receive a command frame when installed in a switching Fabric. The frame identifies a source device and a destination device in the Switching Fabric, a command, and a read/write flag which indicates if the identified source intends to exercise read-only or write access to the destination device. The Switch also includes a processor coupled to the port. The processor is configured to trap the frame and prevent it from reaching the defined destination device in the switching Fabric if both the source and destination devices are in a read-only zone and the flag indicates that the source intends to write to the destination device. In this manner, read-only zones can be implemented in the Switching Fabric.Type: GrantFiled: August 24, 2007Date of Patent: November 30, 2010Assignee: Cisco Technology, Inc.Inventors: Subrata Banerjee, Badri Ramaswamy, Dinesh G.

Patent number: 6701448Abstract: A system and method are disclosed for transferring an enhanced LAN Emulation Client from a first LAN Emulation Server to a second LAN Emulation Server. The addresses of the first LES and the second LES are determined at an LECS. The first LES and the second LES are connected to the LECS. The addresses of the first LES and the second LES are sent to the enhanced LEC so that the addresses of the first LES and the second LES may be stored at the enhanced LEC. When the enhanced LEC determines that the first LES has failed, the address of the second LES is looked up at the enhanced LEC and the enhanced LEC connects to the second LES.Type: GrantFiled: October 12, 1999Date of Patent: March 2, 2004Assignee: Cisco Technology, Inc.Inventors: Cihangir M. Akyol, Bradley A. Benson, Badri Ramaswamy
