1  无线控制器双机直连云集群典型配置

1.1  简介

H3C自主研发的云集群技术，采用物理和容器的双重虚拟架构，将两台AC虚拟化成一台AC，并在虚拟AC上运行基于Docker的容器应用，以保证一台AC故障时WLAN业务不中断。本文介绍了两台AC通过直连组成云集群的典型配置案例。

1.2  组网需求

AC 1和AC 2通过直连链路建立云集群，AC 1作为主设备，云集群和核心交换机之间建立动态聚合链路，用于LACP MAD检测和业务报文的转发。

1.3  配置注意事项

·     使用2台同型号的AC建立云集群。

·     如果通过其他组网方式升级为云集群，建议先清空AC的配置并重启设备，然后搭建集群组网，最后再配置其它业务。

·     云集群中成员设备的成员IP地址必须同网段，故云集群自身需要单独占用一个IP网段，且网络中不允许有其他设备业务IP是此网段，否则可能会导致云集群不通或业务异常，请依据实际情况提前规划。

·     每台设备的成员编号必须在云集群内唯一。

·     Core Switch 1和Core Switch 2为稳定运行的Comware V7 IRF系统。

·     请首先将AC 1和AC 2与交换机相连的业务接口通过shutdown命令关闭，防止在配置动态聚合前设备间产生环路，在集群建立完成并且动态聚合配置完成后再开启接口。

1.4  配置步骤

1.4.1  配置Core 1和Core 2

# 创建二层聚合接口1，并配置该聚合接口对应的聚合组工作在动态聚合模式下。

<Core1> system-view

[Core1] interface bridge-aggregation 1

[Core1-Bridge-Aggregation1] link-aggregation mode dynamic

[Core1-Bridge-Aggregation1] quit

# 将端口Ten-GigabitEthernet1/0/2加入到聚合组1中。

[Core1] interface ten-gigabitethernet 1/0/2

[Core1-Ten-GigabitEthernet1/0/1] port link-aggregation group 1

[Core1-Ten-GigabitEthernet1/0/1] quit

# 将端口Ten-GigabitEthernet2/0/2加入到聚合组1中。

[Core1] interface ten-gigabitethernet 2/0/2

[Core1-Ten-GigabitEthernet1/0/2] port link-aggregation group 1

[Core1-Ten-GigabitEthernet1/0/2] quit

# 开启聚合流量重定向功能。

[Core1] link-aggregation lacp traffic-redirect-notification enable

# Core 2的配置步骤同Core 1。（略）

1.4.2  配置AC 1

(1)     配置设备在云集群中的成员IP为192.168.10.10/24，且本例中AC 1作为Leader。

<AC1> system-view

[AC1] cloud-cluste member 1

[AC1-ccluster-member-1] member-ip 192.168.10.10 24

(2)     集群IP地址即Leader的IP地址，故不需要配置。

(3)     绑定云集群端口

# 在Gigabitethernet1/0/2和Gigabitethernet1/0/3上部署控制通道，以形成冗余备份。

[AC1-ccluster-member-1] cluster-link control bind interface GigabitEthernet 1/0/2

The system will shut down and then bring up the interface after activation the cloud cluster configuration. Continue? [Y/N]: y

[AC1-ccluster-member-1] cluster-link control bind interface GigabitEthernet 1/0/3

The system will shut down and then bring up the interface after activation the cloud cluster configuration. Continue? [Y/N]: y

# 在Ten-Gigabitethernet1/3/9上部署数据通道。

[AC1-ccluster-member-1] cluster-link data bind interface Ten-GigabitEthernet 1/3/9

The system will shut down and then bring up the interface after activation the cloud cluster configuration. Continue? [Y/N]: y

[AC1-ccluster-member-1] quit

(4)     激活云集群配置，设备重启后配置生效。

[AC1] cloud-cluster configuration active

New cluster configuration:

  cloud-cluster service-cluster domain 0

  cloud-cluster hello cloud-timeout 3 service-timeout 5

  cloud-cluster member 1

    member-ip 192.168.10.10/24

    join-cluster ip 192.168.10.10

    role manager-worker

cluster-link control bind interface GigabitEthernet1/0/2

cluster-link data bind interface Ten-GigabitEthernet 1/3/9

The system will activate and save the configuration, and it might do a restart. Continue? [Y/N]:y

The current configuration will be written to the device. Are you sure? [Y/N]:y

Please input the file name(*.cfg)[flash:/startup.cfg]

(To leave the existing filename unchanged, press the enter key):test.cfg

1.4.3  配置AC 2

(1)     配置设备在云集群中的成员编号修改为2，在激活云集群配置后生效。

<AC2> system-view

[AC2] cloud-cluster member 1 renumber 2

This command will take effect after the cloud cluster configuration is activated. The command might result in configuration change or loss when it takes effect. Continue? [Y/N]: y

[AC2] cloud-cluster member 1

(2)     配置设备在云集群中的成员IP为192.168.10.11/24

[AC2-ccluster-member-1] member-ip 192.168.10.11 24

(3)     指定设备要加入的集群IP地址即AC 1的IP地址，IP地址为192.168.10.10。

[AC2-ccluster-member-1] join-cluster ip 192.168.10.10

(4)     绑定云集群端口

# 在Gigabitethernet1/0/2和Gigabitethernet1/0/3上部署控制通道，以形成冗余备份。

[AC2-ccluster-member-1] cluster-link control bind interface GigabitEthernet 1/0/2

The system will shut down and then bring up the interface after activation the cloud cluster configuration. Continue? [Y/N]: y

[AC2-ccluster-member-1] cluster-link control bind interface GigabitEthernet 1/0/3

The system will shut down and then bring up the interface after activation the cloud cluster configuration. Continue? [Y/N]: y

# 在Ten-Gigabitethernet1/3/9上部署数据通道。

[AC2-ccluster-member-1] cluster-link data bind interface Ten-GigabitEthernet 1/3/9

The system will shut down and then bring up the interface after activation the cloud cluster configuration. Continue? [Y/N]: y

[AC2-ccluster-member-1] quit

(5)     激活云集群配置，设备重启后配置生效。

[AC2] cloud-cluster configuration active

New cluster configuration:

cluster-link data bind interface Ten-GigabitEthernet 2/3/9

The system will activate and save the configuration, and it might do a restart. Continue? [Y/N]:y

The current configuration will be written to the device. Are you sure? [Y/N]:y

Please input the file name(*.cfg)[flash:/startup.cfg]

(To leave the existing filename unchanged, press the enter key):test.cfg

1.4.4  配置LACP MAD检测

# 创建二层聚合接口1，并配置该聚合接口对应的聚合组工作在动态聚合模式下。

<AC1> system-view

[AC1] interface bridge-aggregation 1

[AC1-Bridge-Aggregation1] link-aggregation mode dynamic

# 开启LACP MAD检测功能。

[AC1-Bridge-Aggregation1] mad enable

You need to assign a domain ID (range: 0-4294967295)

[Current domain ID is: 0]: 1

The assigned domain ID is: 1

[AC1-Bridge-Aggregation1] quit

# 将端口Ten-GigabitEthernet1/3/10加入到聚合组1中。
