配置案例 | CE交换机如何配置堆叠？
在一个新建的数据中心网络中，要求核心层具有较高的可靠性，并且希望网络结构简单，易于配置和管理。 如图1所示，根据用户需求，核心层SwitchA和SwitchB两台交换机采取堆叠组网。配置堆叠组网图 采用如下的思路配置： 2、按照前期的规划，连接好SwitchA和SwitchB之间的堆叠线缆。 3、在SwitchA和SwitchB上进行堆叠软件配置，包括堆叠成员ID、堆叠优先级、堆叠域编号、堆叠端口等。 4、保存SwitchA和SwitchB的配置，并使能堆叠功能。 5、检查堆叠组建是否成功。 如图2所示，按照前期规划连接SwitchA和SwitchB之间的堆叠线缆。连接的端口包括主控板上的SIP口和业务板上的堆叠物理成员端口。图2 堆叠连接示意图 配置SwitchA的堆叠成员ID为1，优先级为150，Domain ID为10。 配置SwitchB的堆叠成员ID为2，优先级为100，Domain ID为10。 在SwitchA上创建堆叠端口，并将端口10GE1/0/1～10GE1/0/2、10GE2/0/1～10GE2/0/2加入堆叠端口。在SwitchB上创建堆叠端口，并将端口10GE1/0/1～10GE1/0/2、10GE2/0/1～10GE2/0/2加入堆叠端口。SwitchB的配置与SwitchA类似，配置过程略。 被配置为堆叠物理成员端口后，端口下会自动配置 待SwitchA和SwitchB上的物理端口都加入堆叠端口后，再将之前被关闭的端口打开。SwitchB的配置与SwitchA类似，配置过程略。 端口先关闭然后再打开，这样是为了避免端口因产生CRC错包而导致Error-Down。在端口Up的情况下，如果链路一端被配置为堆叠物理成员端口，另一端为普通业务口，此时端口可能会产生CRC错包。 上述配置完成后，执行命令 保存SwitchA的配置并使能堆叠功能。建议先使能规划为主交换机的SwitchA的堆叠功能。这样SwitchA可以先完成重启，从而优先成为主交换机。 使能堆叠功能后，设备会自动重启。 保存SwitchB的配置并使能堆叠功能。 通过Console口或管理网口登录堆叠系统，使用命令display stack查看堆叠是否组建成功。当通过管理网口登录时，需要使用主交换机的IP地址。 如上所示，显示两台交换机的信息，表示堆叠建立成功，且主交换机为成员ID为1的设备，即SwitchA。 在检查堆叠已成功建立后，建议用户立即使用save命令保存堆叠系统配置。Part1组网需求
Part2配置思路
1、提前规划好堆叠方案。Part3操作步骤
1提前规划堆叠方案。
2连接堆叠线缆。
3配置堆叠属性。
