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: 8811214Abstract: Methods and apparatus for performing SPAN for a virtual port are disclosed. Specifically, a frame is received from a first port. The frame or a copy thereof is transmitted to a second port, where the second port is identified in a header of the frame. At least one of the first port and the second port is a virtual port. The frame or a copy thereof is also transmitted to a third port, thereby enabling an analyzer coupled to the third port to analyze traffic received by the third port.Type: GrantFiled: April 9, 2012Date of Patent: August 19, 2014Assignee: Cisco Technology, Inc.Inventors: Samar Sharma, Sanjaya Kumar, Srinivas Avasarala, Gaurav Rastogi, Jeevan Kamisetty

Patent number: 8170025Abstract: Methods and devices are provided for non-disruptive monitoring of network traffic through one or more ports of a Fibre Channel network device. Preferred embodiments of the invention are used in conjunction with the switched port analyzer (“SPAN”) and/or remote SPAN (“RSPAN”) features. SPAN mode operation allows traffic through any Fibre Channel interface of a network device to be replicated and delivered to a single port on the same network device. Ingress SPAN allows the monitoring of some or all packets that ingress a specified port or ports. Egress SPAN allows the monitoring of some or all packets that egress a specified port or ports. RSPAN allows the delivery of the replicated traffic to a port on a remote network device. Filtering may be applied, for example, to SPAN packets having selected virtual storage area network numbers.Type: GrantFiled: November 26, 2008Date of Patent: May 1, 2012Assignee: Cisco Technology, Inc.Inventors: Raymond J. Kloth, Thomas James Edsall, Kalyan K. Ghosh, Gaurav Rastogi, Dinesh Ganapathy Dutt, Matthew Cressa

Patent number: 7793138Abstract: Disclosed are methods and apparatus for detecting anomalies in a storage area network (SAN). Provided are one or more anomaly type(s) and corresponding actions to be performed when the one or more anomaly types are detected. Traffic in the SAN is then inspected in order to detect the one or more provided anomaly type(s). When a one of the provided one or more anomaly type(s) is detected, one or more of the corresponding action(s) is performed. The provided anomaly type(s) may include one or more of the following: a read or write access pattern anomaly, excessive login or control requests, a bandwidth usage anomaly, a configuration anomaly, and a hardware anomaly.Type: GrantFiled: December 21, 2005Date of Patent: September 7, 2010Assignee: Cisco Technology, Inc.Inventors: Gaurav Rastogi, Rajesh Bhandari, Samar Sharma, Fabio Maino
