摘要： A switch is configured to block packets from being transmitted through designated ports. The switch has port bitmap generator configured to obtain a port bitmap and a table is configured to store a block mask indicating which port the packet should not be transmitted. A block mask lookup is configured to determine the block mask for the packet from the table, and a transmit port bitmap generator is configured to determine which ports the packet should be transmitted using the port bitmap and the block mask.

摘要翻译： 交换机被配置为阻止通过指定端口传输数据包。 交换机具有端口位图生成器，其被配置为获得端口位图，并且表被配置为存储指示哪个端口不应该发送该分组的块掩码。 块掩模查找被配置为确定来自表的分组的块掩码，并且发送端口位图生成器被配置为使用端口位图和块掩码来确定应该发送数据包的哪些端口。
