虚拟化堆叠技术-典型配置H3C IRF - 知乎https://zhuanlan.zhihu.com/p/465254812

1.需求

1） 配置两台物理设备为一台逻辑设备虚拟化-堆叠

2） 将线路进行端口捆绑

3） 测试网络端口故障的切换效果

4） 测试设备故障时的切换效果

2.实验拓扑

​

3.IRF配置命令

3.1.主设备配置命令

1) 设备命名

[H3C]sysname SW1

2) 先关闭堆叠的接口

[SW1]int Ten-GigabitEthernet 1/0/52

[SW1-Ten-GigabitEthernet1/0/52]shutdown

3) 配置设备的优先级

[SW1]irf member 1 priority 2

注：优先级默认为1，越大越优，优先为主设备。

4) 关联堆叠接口

[SW1]irf-port 1/1

[SW1]port group interface ten-gigabitethernet 1/0/52

[SW1]int Ten-GigabitEthernet 1/0/52

[SW1-Ten-GigabitEthernet1/0/52]undo shutdown

6) 激活irf配置

[SW1] irf-port-configuration active

3.2.从设备配置命令

1) 设备命名

[H3C]sysname SW2

2) 先关闭堆叠的接口

[SW2]int Ten-GigabitEthernet 1/0/52

[SW2-Ten-GigabitEthernet1/0/52]shutdown

3) 关联堆叠接口

[SW2]irf-port 1/2

[SW2]port group interface ten-gigabitethernet 1/0/52

4) 启用堆叠的接口

[SW2]int Ten-GigabitEthernet 1/0/52

[SW2-Ten-GigabitEthernet1/0/52]undo shutdown

5) 激活irf配置

[SW2] irf-port-configuration active

4.其他配置命令

4.1.端口捆绑配置命令

堆叠设备上配置捆绑

[SW1]int Bridge-Aggregation 2

[SW1]int ran ten 1/0/50 ten 2/0/51

[SW1-if-range]port link-aggregation group 2

[SW1]int Bridge-Aggregation 2

[SW1-Bridge-Aggregation2]port link-type trunk

[SW1-Bridge-Aggregation2]port trunk permit vlan all

其他设备配置捆绑

[S5820] int Bridge-Aggregation 2

[S5820]int ran ten 1/0/50 ten 1/0/51

[S5820-if-range]port link-aggregation group 2

[S5820]int Bridge-Aggregation 2

[S5820-Bridge-Aggregation2]port link-type trunk

[S5820-Bridge-Aggregation2]port trunk permit vlan all

4.2.配置svi地址

堆叠设备上配置SVI

vlan 10

int vlan 10

ip add 10.1.1.1 24

其他设备上配置SVI

vlan 10

int vlan 10

ip add 10.1.1.2 24

5.2.切换测试

S5820上发起ping堆叠设备

ping -c 100000 10.1.1.1

Ping 10.1.1.1 (10.1.1.1): 56 data bytes, press CTRL_C to break

6.总结

整体经典配置得到预期的效果，两台物理设备虚拟化为一台逻辑设备，统一化管理，并具有逻辑设备进行链路聚合功能，在极端情况下物理设备中断，恢复丢包可控制在5个以内，具有良好的风险控制。

但堆叠具有同厂家同型号才能进行，具有排外性，而且技术上是厂家私有的黑盒子，凡事有利有弊。
