1-10the device to be configured as the management device before establishing a cluster. Meanwhile, the IPaddresses of the VLAN interfaces of the management device and member devices cannot be in thesame network segment as that of the cluster address pool; otherwise, the cluster cannot work normally.When a candidate device is added to a cluster, the management device assigns it a private IP addressfor it to communicate with other devices in the cluster.You can establish a cluster in two ways: manually and automatically. With the latter, you can establish acluster according to the prompt information. The system:1) Prompts you to enter a name for the cluster you want to establish;2) Lists all the candidate devices within your predefined hop count;3) Starts to automatically add them to the cluster.You can press Ctrl+C anytime during the adding process to exit the cluster auto-establishment process.However, this will only stop adding new devices into the cluster, and devices already added into thecluster are not removed.Follow these steps to manually establish a cluster:To do… Use the command… RemarksEnter system view system-view —Specify the management VLAN management-vlan vlan-idOptionalBy default, VLAN 1 is themanagement VLAN.Enter cluster view cluster —Configure the private IP addressrange for member devicesip-pool ip-address { mask |mask-length }RequiredNot configured by default.Manuallyestablish aclusterbuild cluster-nameEstablish acluster Automaticallyestablish aclusterauto-build [ recover ]RequiredUse either approachBy default, the device is not themanagement device.Enabling Management VLAN Auto-negotiationThe management VLAN limits the cluster management range. If the device discovered by themanagement device does not belong to the management VLAN, meaning the cascade ports and theports connecting with the management device do not allow the packets from the management VLAN topass, and the new device cannot be added to the cluster. Through the configuration of the managementVLAN auto-negotiation function, the cascade ports and the ports directly connected to the managementdevice can be automatically added to the management VLAN.Follow these steps to configure management VLAN auto-negotiation:To do… Use the command… RemarksEnter system view system-view —Enter cluster view cluster —Enable management VLANauto-negotiationmanagement-vlansynchronization enableRequiredDisabled by default.
