Abstract:
A system can collect, from an address resolution protocol (“ARP”) cache of a managed virtual network function (“VNF”), at least one active entry corresponding to at least one active element of a plurality of virtual local area network (“VLAN”) networks. The system can check the ARP cache for an entry associated with at least one of the plurality of VLAN elements. The system can determine whether an entry associated with at least one of the plurality of VLAN elements was found. In response to determining that an entry associated with at least one of the plurality of VLAN elements was not found, the system can send an ARP request to the plurality of VLAN elements, wait for an ARP response, and, in response to determining that an ARP response has not been received, generate a notification that VLAN connectivity has been lost.

Claim (Index 15):
A method comprising:\n generating, by a fault management system comprising a processor, an address resolution protocol request; sending, by the fault management system, the address resolution protocol request to a plurality of virtual local area network elements of a customer premises portion of a virtual local area network, wherein a managed virtual network function is also part of the virtual local area network; waiting, by the fault management system, for an address resolution protocol response from at least one of the plurality of virtual local area network elements of the customer premises portion of the virtual local area network; determining, by the fault management system, whether an address resolution protocol response has been received from at least one of the plurality of virtual local area network elements of the customer premises portion of the virtual local area network; and in response to determining that an address resolution protocol response has not been received from any of the plurality of virtual local area network elements of the customer premises portion of the virtual local area network,\n determining, by the fault management system, that connectivity between the managed virtual network function of the virtual local area network and the plurality of virtual local area network elements of the customer premises portion of the virtual local area network has been lost, wherein determining that connectivity between the managed virtual network function of the virtual local area network and the plurality of virtual local area network elements of the customer premises portion of the virtual local area network has been lost is performed without installation, on any of the plurality of virtual local area network elements of the customer premises portion of the virtual local area network, of any software associated with determining whether connectivity has been lost, and \n generating, by the fault management system, a notification that connectivity between the managed virtual network function of the virtual local area network and the plurality of virtual local area network elements of the customer premises portion of the virtual local area network has been lost.
