Patent number: 10243888Abstract: Methods and systems according to one or more embodiments establish communication across separate IP domains that are on the same layer 2 bridged domain. In an embodiment, a method includes receiving a configuration of a first IP address of a first node on a first side of a switch and a second IP address of a second node on a second side of the switch, wherein the first and second IP addresses are of different domains and are to be translated in each direction with respect to the switch, wherein the switch further comprises an integrated block adapted to do translation at line rate. Based on the configuration, the method also includes modifying, by the switch, packets of an applicable protocol in each direction so that the first and second IP addresses are changed for each domain such that either side of the switch acts as if an opposite side is on the same domain so that layer 2 communication is established.Type: GrantFiled: April 24, 2017Date of Patent: March 26, 2019Assignee: Cisco Technology, Inc.Inventors: Marc Bennett, Yen Teresa Nguyen, Jonathan Harrod, Charles Wu, Aijaz Pathan

Patent number: 8719253Abstract: Consistent with embodiments of the present invention, a method may be provided comprising receiving a search string corresponding to a desired node comprising a target parameter, a policy parameter, and a class parameter. The target parameter may be referenced with a target index table to determine which interfaces to search. The policy parameter may be referenced with a policy index table to determine a node-id of a policy node corresponding to the policy parameter. A level for the desired node may be determined based on the node-id. The class parameter may be referenced with the determined node-id with a class index table to access a bucket location. The desired node may then be searched for with the determined node-id at the determined level.Type: GrantFiled: December 1, 2010Date of Patent: May 6, 2014Assignee: Cisco Technology, Inc.Inventors: Vijay Srinivasan, Arun Srinivasan, Jay Shah, Aijaz Pathan, Yen Teresa Nguyen

Patent number: 6700498Abstract: A system and method determines the environmental configuration of telecommunications equipment having interchangeable components to provide an alarm if an improper environmental configuration exists. A configuration engine associated with the network management system of the telecommunications equipment determines the environmental rating of components added to or removed from the telecommunications equipment by querying flash memory associated with the component. If components designed for controlled environmental conditions and components designed for uncontrolled environmental conditions are both present in the telecommunications equipment, then component engine 30 sets the alarm to alert the user of an improper environmental configuration.Type: GrantFiled: October 18, 2002Date of Patent: March 2, 2004Assignee: Cisco Technology, Inc.Inventors: Richard Jeske, Patrick E.
