摘要： In an embodiment, a method is disclosed for operating a network having a group of bridges connected together to form a ring, each bridge having two ports assigned to the ring to form a group of ring ports. The claimed embodiment includes forwarding information through the ring according to one or more spanning tree instances, each instance designating one of the group of ring ports as a respective alternate port that is in a state of discarding. Responsive to learning of a failure by a bridge within the ring, a determination is made, for each spanning tree instance, whether the bridge contains a respective alternate port and if the bridge contains a respective alternate port, changing the state of the respective alternate port to forwarding.

摘要： A stack switch for performing pass-through forwarding operations, assigning stack switch identifiers to a plurality of stack switches, temporarily disabling supervision messages exchanged by stack switches, and electing a primary master stack switch is disclosed. In the pass-through mode, the stack switch automatically forwards packets between stack ports independent of their destination address to maintain connectivity between adjacent stack switches while conventional bridging and routing operations are disabled. The sequential identifiers are also preferably assigned in accordance with the sequential position of the various stack switches to better reflect the topology of those switches. The switch is also preferably adapted to temporarily disable the transmission of supervision messages between stack switches to prevent re-assignment of network management functions when switch resources are low. The switch may execute a stack switch identifier numbering scheme based on the time the switch became operational.
摘要翻译：一种用于执行传递转发操作的堆叠交换机，向多个堆叠交换机分配堆叠交换机标识符，临时禁用由堆叠交换机交换的监督消息，以及选择主主堆叠交换机。在直通模式下，堆叠交换机自动转发堆栈端口之间的数据包，独立于目标地址，以保持相邻堆叠交换机之间的连通性，而传统的桥接和路由操作被禁用。顺序标识符还优选地根据各种堆叠交换机的顺序位置来分配，以更好地反映那些交换机的拓扑。交换机还优选地适于暂时禁用堆叠交换机之间的监督消息的传输，以防止当交换机资源较低时重新分配网络管理功能。交换机可以根据交换机的运行时间执行堆叠交换机标识符编号方案。
