华为三台堆叠-环形.doc
配置三台交换机堆叠示例（环形拓扑）图1配置环形堆叠组网图组网需求在一个新建的企业网络中，要求接入设备具有充足的端口数目，并且希望网络结构简单，易于配置和管理。如图1所示，SwitchA、SwitchB和SwitchC三台接入交换机组成环形堆叠系统。配置思路采用如下的思路配置：1. 提前规划好堆叠方案。2. 按照前期的规划，完成各台交换机的堆叠配置，包括堆叠成员ID、堆叠优先级、堆叠域编号、堆叠端口等。完成后保存配置并将交换机下电。3. 连接交换机之间的堆叠线缆，然后将交换机上电。4. 检查堆叠组建是否成功。说明：本示例以先配置软件再连接线缆的方式组建堆叠。如果是先连接线缆再配置软件方式，请参照配置两台交换机堆叠示例（先连线后配置方式）的思路进行配置。操作步骤1. 提前规划堆叠方案。 规划SwitchA的堆叠成员ID为1，SwitchB的成员ID为2，SwitchC的成员ID为3。 规划SwitchA作为主交换机，其堆叠优先级最高，为150。SwitchB的堆叠优先级为120。SwitchC的堆叠优先级为90。 规划堆叠域编号（Domain ID）为10，不与网络中其他堆叠系统的域编号冲突。 规划堆叠连接拓扑为环形。成员设备间用于堆叠连接的端口如图2所示。图2堆叠端口连接示意图2. 配置堆叠属性。# 配置SwitchA的堆叠优先级为150，Domain ID为10。缺省情况下，设备的堆叠成员ID为1。此处默认SwitchA的堆叠成员ID为1，无需配置。<HUAWEI> system-viewHUAWEI sysname SwitchA*HUAWEI commitSwitchA stackSwitchA-stack stack member 1 priority 150*SwitchA-stack stack member 1 domain 10*SwitchA-stack quit*SwitchA commit# 配置SwitchB的堆叠成员ID为2，优先级为120，Domain ID为10。<HUAWEI> system-viewHUAWEI sysname SwitchB*HUAWEI commitSwitchB stackSwitchB-stack stack member 1 priority 120*SwitchB-stack stack member 1 domain 10*SwitchB-stack stack member 1 renumber 2 inherit-configWarning: The stack configuration of member ID 1 will be inherited to member ID 2 after the device resets. Continue? Y/N: y*SwitchB-stack quit*SwitchB commit说明：因SwitchB尚未重启，当前堆叠成员ID还是1，所以此时仍使用member 1来进行堆叠配置。因为修改堆叠成员ID时指定了inherit-config参数，所以SwitchB重启后会继承member 1的堆叠配置；如果不指定inherit-config参数，那么SwitchB重启后不会继承member 1的堆叠配置，需要使用member 2重新进行堆叠配置。# 配置SwitchC的堆叠成员ID为3，优先级为90，Domain ID为10。<HUAWEI> system-viewHUAWEI sysname SwitchC*HUAWEI commitSwitchC stackSwitchC-stack stack member 1 priority 90*SwitchC-stack stack member 1 domain 10*SwitchC-stack stack member 1 renumber 3 inherit-configWarning: The stack configuration of member ID 1 will be inherited to member ID 3 after the device resets.
