  • Method and system for removing authentication of a supplicant
    Patent number: 8677478
    Abstract: According to one embodiment, a method for removing authentication of a supplicant includes monitoring communication between the supplicant and an authenticator. The method also includes determining, based on the monitored communication, the MAC address for the supplicant and an attachment port of the supplicant to the intermediate network device disposed between the supplicant and the authenticator through which the monitored communication occurs. The method also includes determining that the supplicant no longer has a link connection with the intermediate network device, and in response, sending via the intermediate network device a logoff message having a spoofed source address of the supplicant to the authenticator.

  • Method for bring-up of voice over internet protocol telephones
    Patent number: 8194689
    Abstract: A system and method for implementing telephony devices in a distributed network environment is disclosed. The present invention provides for voice transmissions to be given a dedicated virtual local area network (“VLAN”) for packet transmission and reception to prevent poor quality of service. Non-voice data packets are transmitted on a separate VLAN.

  • Apparatus and methods for supporting 802.1X in daisy chained devices
    Patent number: 7539189
    Abstract: Disclosed are apparatus and methods for authenticating a device to access a network through an access control port. In one embodiment, one or more first authentication packets for authenticating a first device or user to access a first network domain via a particular access port of a network device are received, for example, by an access control port. The particular access port is configured to control access for packets attempting to ingress into one or more network domains. When the first device or user is authorized to access the first domain, a first binding between the first device and the first domain is formed. The first binding specifies that the first device is allowed to access the first domain and the first binding is associated with the particular access port of the network device. When a packet is received that is attempting to ingress into the first domain and the ingressing packet matches the first binding, the ingressing packet is allowed to access the first domain.
