摘要： A method in an active network element. The network element is coupled with a standby network element by an inter-chassis communication channel used to synchronize session state for sessions handled by the active network element from the active network element to the standby network element. The network element is deployed in a Layer 3 network that is used to transmit Layer 2 data. The method is one of limiting disruption in the handling of the sessions. The method includes monitoring a Layer 2 interface for failures and monitoring a Layer 3 interface for failures. A failure is detected on the Layer 2 interface. The network element communicates with the standby network element, over the inter-chassis communication channel, in response to detecting the failure on the Layer 2 interface, to have the standby network element at least assist with the handling of the sessions.
摘要翻译：活动网络元素中的一种方法。网络元件通过机架间通信信道与待机网络元件耦合，所述机架间通信信道用于将由活动网络元件处理的会话的会话状态从活动网络元件同步到备用网络元件。网元部署在用于传输二层数据的三层网络中。该方法是限制会话处理的中断。该方法包括监控二层接口故障，监控三层接口故障。在二层接口上检测到故障。响应于检测到二层接口上的故障，网元通过机架间通信信道与备用网元通信，使备用网络元件至少协助处理会话。
