Patent number: 10700956Abstract: An apparatus, computer program product, and method relating to identifying and configuring an access point (AP) as a network sniffer. A network controller identifies a plurality of sniffer targets for which at least one of a plurality of sniffer candidate access points an act as a network sniffer. The controller receives a desired sniffer target. The controller selects a first AP, of the plurality of sniffer candidate APs, for use as a network sniffer, based on the identified plurality of sniffer targets and the desired sniffer target. The controller configures a radio in the first AP as a network sniffer to monitor network traffic related to the desired sniffer target.Type: GrantFiled: January 19, 2018Date of Patent: June 30, 2020Assignee: Cisco Technology, Inc.Inventors: Jie Jiang, Vishal S. Desai, Kasi Nalamalapu, Manoj Gupta, Ramadhasan Thangachamy, Venkatesh Kanagasabapathy

Patent number: 10171260Abstract: Techniques are provided to manage how router advertisement messages are forwarded for ultimate wireless transmission in a wireless network. In one embodiment, a multicast router advertisement message intended for a virtual local area network is converted into individual unicast router advertisement messages directed to specific wireless mobile client devices that are part of that virtual local area network. In another embodiment, router advertisement messages are routed between controllers according to the current location of a wireless mobile client device. In still other embodiments, techniques are provided to minimize the volume of the router advertisement messages sent over a wireless network, and to proactively send a unicast router advertisement message to a mobile client device that has performed a handoff, without waiting for a router solicitation message.Type: GrantFiled: June 6, 2016Date of Patent: January 1, 2019Assignee: Cisco Technology, Inc.Inventors: Srinath Gundavelli, Abhijit Choudhury, Rohit Suri, Venkatesh Kanagasabapathy, Bhavannarayana Nelakanti, Sudhir Jain

Patent number: 8724583Abstract: Techniques are provided herein to support roaming of wireless mobile client devices from one wireless local area network access point device to another wireless local area network access point device. Neighbor discovery messages are received from wireless mobile client devices. A neighbor discovery message specifies a target address for a neighbor discovery function. A response to a neighbor discovery message is sent to a wireless mobile client device such that the response message appears to have been sent by a wireless mobile client device that has an address that corresponds to the target address of the neighbor discovery message.Type: GrantFiled: November 4, 2009Date of Patent: May 13, 2014Assignee: Cisco Technology, Inc.Inventors: Srinath Gundavelli, Abhijit Choudhury, Rohit Suri, Venkatesh Kanagasabapathy, Bhavannarayana Nelakanti, Sudhir Jain
