华为 4 台交换机 iStack 堆叠部署教程

一、堆叠的作用与优势（非常重要）

二、机柜实体交换机结构

三、堆叠拓扑结构（环形最优）

四、物理连接方式（必须按此接线）

SW1 49  → SW2 50
SW2 49  → SW3 50
SW3 49  → SW4 50
SW4 49  → SW1 50

五、完整配置命令（逐台执行）

system-view
stack
stack member 1 renumber 1

interface stack-port 1/1
port member-group interface XGigabitEthernet 1/0/49

interface stack-port 1/2
port member-group interface XGigabitEthernet 1/0/50

save

system-view
stack
stack member 1 renumber 2

interface stack-port 2/1
port member-group interface XGigabitEthernet 2/0/49

interface stack-port 2/2
port member-group interface XGigabitEthernet 2/0/50

save

system-view
stack
stack member 1 renumber 3

interface stack-port 3/1
port member-group interface XGigabitEthernet 3/0/49

interface stack-port 3/2
port member-group interface XGigabitEthernet 3/0/50

save

system-view
stack
stack member 1 renumber 4

interface stack-port 4/1
port member-group interface XGigabitEthernet 4/0/49

interface stack-port 4/2
port member-group interface XGigabitEthernet 4/0/50

save

六、主备切换机制说明

七、验证命令
