無線雲集群問題

參考配置：

2.1  組網需求

AC 1和AC 2通過直連鏈路建立雲集群，AC 1作為主設備，雲集群和核心交換機之間建立動態聚合鏈路，用於LACP MAD檢測和業務報文的轉發。

圖20 雲集群組網圖

2.2  配置注意事項

使用2台同型號的AC建立雲集群。

如果通過其他組網方式升級為雲集群，建議先清空AC的配置並重啟設備，然後搭建集群組網，最後再配置其它業務。

2.3  功能配置

2.3.1  配置前提

·     Core Switch 1和Core Switch 2為穩定運行的Comware V7 IRF係統。

·     請首先將AC 1和AC 2與交換機相連的業務接口通過shutdown命令關閉，防止在配置動態聚合前設備間產生環路，在集群建立完成並且動態聚合配置完成後再開啟接口。

2.3.2  配置Core 1和Core 2

# 創建二層聚合接口1，並配置該聚合接口對應的聚合組工作在動態聚合模式下。

<Core> system-view

[Core] interface bridge-aggregation 1

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

[Core-Bridge-Aggregation1] quit

# 將端口Ten-GigabitEthernet1/0/2加入到聚合組1中。

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

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

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

# 將端口Ten-GigabitEthernet2/0/2加入到聚合組1中。

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

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

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

# 開啟聚合流量重定向功能。

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

2.3.3  配置AC 1

(1)     配置設備在雲集群中的成員編號

# 設備出廠默認的成員編號為1，故不需要配置。

(2)     配置設備在雲集群中的成員IP

# 雲集群中成員設備的成員IP地址必須同網段，故雲集群自身需要單獨占用一個IP網段，請依據實際情況提前規劃。本文以192.168.10.x/24舉例。

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

(3)     指定設備要加入的集群IP地址

# 集群IP地址即Leader的IP地址，本例中AC 1作為Leader，故不需要配置。

(4)     綁定雲集群端口

# 雲集群需要配置控製通道和數據數據通道的物理接口。在Gigabitethernet1/0/2和Gigabitethernet1/0/3上部署控製通道，以形成冗餘備份。

[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上部署數據通道。為滿足數據通道的帶寬需求，推薦數據通道使用Ten-Gigabitethernet接口或至少2個Gigabitethernet接口。

[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

(5)     激活雲集群配置

# 設備重啟後配置生效。

[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

2.3.4  配置AC 2

(1)     配置設備在雲集群中的成員編號

# 每台設備的成員編號必須在雲集群內唯一，故將設備在雲集群中的成員編號修改為2。在激活雲集群配置後生效。

<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

[AC2-ccluster-member-1]

(2)     配置設備在雲集群中的成員IP

# 雲集群中成員設備的成員IP地址必須同網段。

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

(3)     指定設備要加入的集群IP地址

# 集群IP地址即Leader的IP地址，本例中AC 1作為Leader，IP地址為192.168.10.10。

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

(4)     綁定雲集群端口

# 雲集群需要配置控製通道和數據數據通道的物理接口。在Gigabitethernet1/0/2和Gigabitethernet1/0/3上部署控製通道，以形成冗餘備份。

[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

    role manager-worker

cluster-link control bind interface GigabitEthernet2/0/2

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

2.3.5  配置LACP MAD檢測

# 創建二層聚合接口1，並配置該聚合接口對應的聚合組工作在動態聚合模式下。
