集群/堆叠的常用部署实施方式,你会吗?

你们好,我的网工朋友。

交换机的连接方式大家应该都知道吧,一共有三种,分别是:级联、堆叠和集群。

级联一般用来实现多台交换机之间的互相连接。

堆叠和集群,就总有网工把这两给搞迷糊了。

堆叠就是将多台支持堆叠特性的交换机通过堆叠线缆连接在一起,从逻辑上虚拟成一台交换设备,作为一个整体参与数据转发。

集群则是将两台支持集群特性的交换机设备组合在一起,从逻辑上虚拟成一台交换设备。

通过使用堆叠、集群技术结合链路聚合技术可以简单构建高可靠、无环的园区网络。

那具体怎么操作,今天就给你分享个经典案例,说说集群、堆叠的常用部署实施方式。

今日文章阅读福利:《思科交换机级联、堆叠、虚拟技术对比(26页)》

其实端口扩展也是在LAN网络设计中经常会碰到的问题。

目前广泛使用的扩展方式包括级连扩展、堆叠技术扩展和虚拟机框三种技术

想搞懂这三种技术,私信我,发送暗号“堆叠”,限时获取资料。

01 通用基础架构拓扑图

核心层使用两台框式交换机组建集群,汇聚层使用两台盒式交换机组建堆叠,核心层的集群与汇聚层的堆叠使用Eth-Trunk相连。

04 配置步骤1:搭建集群环境

01 交换机下电,安装用于集群业务板并根据下面连线图连线集群线缆和多主检测线缆。

集群/堆叠的常用部署实施方式,你会吗?_第7张图片 集群线缆连线图

出于可靠性考虑,推荐按照下面方式进行连线:

  • 一块业务板上建议至少有两个物理成员端口加入到一个逻辑集群端口。
  • 上行端口和配置多主检测的端口所在业务板建议属于非组建集群的业务板。

02 为两台交换机上电,按照数据规划分别对两台框式交换机进行配置

03 交换机重启后,查看集群是否组建成功

#通过交换机框上主控板的集群指示灯查看集群状态。

Switch1主控板上ACT灯绿色常亮,表示该主控板为集群系统主用主控板,Switch1为主交换机。

Switch2主控板上ACT灯绿色闪烁,表示该主控板为集群系统备用主控板,Switch2为备交换机。

#通过任意主控板上的Console口登录集群系统,使用命令行查看集群组建是否成功。

根据集群优先级,优先级大的Switch1会成为集群系统的主框,执行命令display device查看设备状态时,集群系统名为Switch1。

04 集群组建完成,配置多主检测

集群组建完成后,为防止集群故障分裂导致多主影响业务,在两台交换机直接连接一条线缆,用于多主检测。

线缆对应的接口分别为XGE1/1/0/10和XGE2/1/0/10,如图2-5所示。

05 配置步骤2:搭建堆叠环境

这里以搭建堆叠AGG1为例,AGG2的搭建和配置过程与AGG1相同。

01 按照数据规划分别对两台盒式交换机进行配置

如果使用专用堆叠线缆堆叠,此步配置可以省略。
