| 1. | Outage : a backbone switch failed . . . see technical news
由于主力交换机出问题而停机，详情请看技术新闻。 |
| 2. | Typically , permanent virtual circuits are set up between multiple backbone switches and between switches and devices with heavy network traffic
一般而言，永久性虚拟电路建在多个主干网交换机之间和交换机与网络信息流量大的设备之间。 |
| 3. | Like a backbone switch , a workgroup switch can support a large number of ethernet addresses per port and can replace a router and segment networks or users
工作组交换机像基干交换机一样，能在每个端口上支持大量的以太网地址，并能代替路由器和分段网或用户。 |
| 4. | With gigabit traffic streams funneling through the lan backbone , carrying a mix of data , graphics , voice and video exchange , backbone switches have to assume the mantle of high - end functionality
由于千兆位流量通过局域网主干网汇流在一起，运载着数据、图形、声音和视频交换的混合信息，主干网交换机必须承担高档功能的外包装。 |
| 5. | The switched internetwork model , in which servers are treated simply as end nodes on a backbone switch , doesn ' t scale for environments in which enterprise applications are distributed across any servers
在交换的网络互连模型中，服务器只是被简单地当作主干交换机的最终节点，此模型与企业应用被分布在多台服务器的环境不相衬。 |
| 6. | Redundant power supplies , hot - swappable modules and spanning tree protocol ( stp ) support are all mandatory elements of a backbone switch , as is support for emerging switch technologies , including virtual lans
具有冗余能力的电源、可热插拔的模块和对生成树协议（ stp ）的支持都是基干交换机必备的成分，实际上它支持新出现的交换技术，如虚拟局域网。 |
| 7. | While they typically do not include the protocol filtering and other routing functions offered by backbone switches , some workgroup switches support advanced software including stp , simple network management protocol and virtual lans
一般而言，虽然它们不包含基干交换机提供的协议过滤和其它路由功能，但某些工作组交换机支持高级软件，如stp 、简单网络管理协议和虚拟局域网。 |
