Abstract: A method, apparatus and computer program product for debugging private Virtual Local Area Networks (VLANs) is provided. In a Connectivity Fault Management (CFM) domain wherein a primary Virtual Local Area Network (VLAN) includes promiscuous ports and wherein a secondary VLAN includes isolated ports, a determination is made at a first network device whether a CFM packet is received on a primary VLAN or a secondary VLAN. When the CFM packet is received on a secondary VLAN, then the CFM packet is responses to on the primary VLAN.

Abstract: Multicast link trace Connectivity Fault Management (CFM) is implemented in an Ethernet network by causing nodes on the network which perform Reverse Path Forwarding Check (RPFC) based on packet Source Address (SA) to not update the packet SA when updating the content of the CFM message. Alternatively multicast CFM is implemented by causing nodes on the network to update the packet SA when the content of the CFM message is updated, but cause a secondary RPFC process to be implemented by a control process in connection with processing the CFM message. The secondary RPFC process is based on a combination of source and content contained in the payload of the CFM message.

Abstract: A computer-implemented method, apparatus and software for debugging auto-attach entities is presented. A Continuity Fault Management (CFM) request for a service is received over a network at an Auto-Attach (AA) server. The AA server responds with a first response regarding the AA server on the service. The AA server also responds to the CFM request with a second response regarding any AA clients and any AA proxies on the service.

Abstract translation: 组播链路跟踪连通性故障管理（CFM）在以太网中实现，通过使基于分组源地址（SA）的执行反向路由转发检查（RPFC）的网络上的节点在更新内容的时候不更新分组SA CFM消息。 或者，当CFM消息的内容被更新时，通过使网络上的节点更新分组SA来实现组播CFM，但是通过与处理CFM消息相关的控制过程来实现辅助RPFC过程。 次级RPFC进程基于CFM消息的有效载荷中包含的源和内容的组合。
