    • A network node is described herein which ensures that whenever an ingress station (e.g., PC) communicates a special MAC DA packet then that packet's copies are forwarded (via a high availability VLAN) to its port(s) that are associated with remote network node(s) and/or egress server(s) (e.g., firewall(s)) and not forwarded to its port(s) that are associated with data storage server(s) or ingress station(s) (e.g., PCs). The network node also ensures that whenever an ingress station (e.g., PC) communicates a normal MAC DA packet then that packet's copies are forwarded to all of its port(s) that are associated with ingress station(s), remote network node(s), egress server(s) and/or data storage server(s) so that these stations/servers can maintain their connectivity via a default VLAN.
    • 这里描述了一种网络节点,其确保每当入站(例如,PC)通信特殊MAC DA分组时,该分组的副本(经由高可用性VLAN)被转发到其与远程网络节点相关联的端口 和/或出口服务器(例如,防火墙),并且不转发到与数据存储服务器或入站(例如PC)相关联的端口。 网络节点还确保每当进入站(例如PC)通信正常的MAC DA分组时,该分组的副本被转发到与入站相关联的所有端口,远程网络节点 ),出口服务器和/或数据存储服务器,以便这些站/服务器可以通过默认VLAN维护其连接。
