  • Distributing ethernet alarm indication signal information to multiple virtual local area networks
    Patent number: 8547832
    Abstract: Ethernet Alarm Indication Signal (ETH-AIS) information for multiple Virtual Local Area Networks (VLANs) is consolidated and distributed to the multiple VLANs in a single Ethernet frame. Note, as used herein, “Alarm Indication Signal (ETH-AIS)” refers to an IEEE 802.x or ITU-T Y.1731 Ethernet Alarm Indication Signal. A device receiving the Ethernet frame with the consolidated ETH-AIS information typically forwards the frame out each port that communicates traffic for one of the VLANs included in the consolidated ETH-AIS information.
    Type: Grant
    Filed: March 22, 2010
    Date of Patent: October 1, 2013
    Assignee: Cisco Technology, Inc.
    Inventors: Nitin Gupta, Sonal Shah, Aravindan Ramalingam, Norman William Finn

  • Controlled Propagation of VLAN Declarations
    Publication number: 20110096784
    Abstract: The propagation of virtual local area network (VLAN) declarations is controlled, to minimize or eliminate their propagation to packet switching devices which do not carry traffic for a corresponding VLAN. Initially and in response to a first time receipt of a VLAN declaration for a particular VLAN on a particular interface of a packet switching device, VLAN declarations for the particular VLAN is propagated out every interface of the packet switching device. After a predetermined time frame, if a VLAN declaration has not been received on a particular interface for an active VLAN, propagation of the VLAN declarations for the active VLAN will be suppressed for the particular interface.
