近几年来,生产以太网交换器产品的厂商不断拥现,而每个厂商的产品系列又不断丰富,且不断有新的特性加到以太网交换器中。本文将讨论19个不同的交换器特性。 1 端口—地址表大小 一台交换器,把数据包按目的地址正确转发的能力取决于对端口—地址表的使用。类似地,交换器支持一定数目工作站的能力,也取决于端口—地址表中表项的数目。所以,端口—地址表大小可以被看作是影响交换器支持网络设备的能力的一个约束条件。
In recent years, manufacturers of Ethernet switch products continue to emerge, and each vendor’s product line is constantly enriched, and constantly new features added to the Ethernet switch. This article will discuss 19 different switch features. 1 port - address table size A switch, the ability to forward the correct packet destination address depends on the use of the port - address table. Similarly, the ability of a switch to support a given number of workstations also depends on the number of entries in the port-address list. Therefore, the size of the port-address table can be seen as a constraint on the ability of the switch to support networked devices.
