Aruba ESP园区局域网设计

Aruba CX交换机系列为园区核心、汇聚和接入层提供了一系列产品。这些交换机基于AOS-CX的云原生操作系统构建,以增强网络弹性并推动自动化,AOS-CX实现了以数据库为中心的运行模式。

各种组织可以依赖Aruba CX交换机来满足整个园区的关键任务需求,得益于其始终在线的PoE(always-on PoE)、用于堆叠接入的虚拟交换框架(VSF)和用于核心及汇聚冗余的虚拟交换扩展(VSX)。

Aruba ESP园区局域网设计主要专注于两种最常见的拓扑结构:

  • 堆叠核心(collapsed core)的两层(Two-tier)设计
  • 使用汇聚的三层(Three-tier)设计

冗余路由链路是交换机之间首选的上行链路配置。尽管目前部署的大多数网络都是为核心层或汇聚层的2层接入和路由而配置的,但着眼于软件定义叠加拓扑的企业应开始转向3层接入,并在边缘进行路由,以提高底层网络的弹性。

Aruba ESP园区局域网设计可能包含以下一个或多个元素:

  • Aruba Central
  • Aruba ClearPass
  • Aruba CX 8xxx 以太网交换机
  • Aruba CX 6xxx 以太网交换机
