摘要： PROBLEM TO BE SOLVED: To provide a method of accurately locating a loop fault port.SOLUTION: A switching device receives an Ethernet frame, learns a MAC address according to a source MAC address of the Ethernet frame, and determines a learned associated port of the MAC address as a first port of the MAC address; uses a port after hopping as a second port of the MAC address when the associated port of the MAC address undergoes hopping for a first time after the MAC address is learned; and determines the second port as a loop fault port if the total number of hops of the associated port of the MAC address in a specified time is greater than or equal to a preset threshold.

摘要： PROBLEM TO BE SOLVED: To reduce the problem of the disturbed sequence of a plurality of unicast packets successively transmitted in order, before the update of a MAC address table is completed in a ring failure avoidance system.SOLUTION: A network switch sets a broadcast flag of a port in the loop of an Ethernet ring to a set state before the completion of updating the MAC address table. When a broadcast flag of a destination port corresponding to the destination address of a unicast packet received by the network switch is in the set state, the network switch broadcasts the unicast packet. Accordingly, the network switch in the loop of the Ethernet ring can recover the interrupted unicast traffic without waiting for the completion of the MAC address table update. Thus, the unicast traffic can be recovered in the middle of the execution of the Ethernet ring failure avoidance system.
摘要翻译：要解决的问题：为了减少在环路故障回避系统中完成MAC地址表的更新之前依次顺序发送的多个单播分组的干扰序列的问题。解决方案：网络交换机在完成更新MAC地址表之前，将以太网环路环路中的端口的广播标志设置为设置状态。当与由网络交换机接收到的单播分组的目的地地址相对应的目的地端口的广播标志处于设置状态时，网络交换机广播单播分组。因此，以太网环路环路中的网络交换机可以恢复中断的单播流量，而无需等待MAC地址表更新的完成。因此，在以太网环路故障回避系统的执行过程中，可以恢复单播流量。版权所有（C）2013，JPO＆INPIT
