1-14the member devices through the management device. You can manage member devices in a clusterthrough switching from the operation interface of the management device to that of a member device orconfigure the management device by switching from the operation interface of a member device to thatof the management device.Follow these steps to configure access between member devices of a cluster:To do… Use the command… RemarksSwitch from the operation interface ofthe management device to that of amember devicecluster switch-to { member-number |mac-address mac-address | sysnamemember-sysname }RequiredSwitch from the operation interface of amember device to that of themanagement devicecluster switch-to administrator RequiredTelnet connection is used in the switching between the management device and a member device.Note the following when switching between them:z Authentication is required when you switch from a member device to the management device. Theswitching fails if authentication is not passed. Your user level is allocated according to thepredefined level by the management device if authentication is passed.z When a candidate device is added to a cluster and becomes a member device, its super passwordwill be automatically synchronized to the management device. Therefore, after a cluster isestablished, it is not recommended to modify the super password of any member (including themanagement device and member devices) of the cluster; otherwise, the switching may failbecause of an authentication failure.z If the member specified in this command does not exist, the system prompts error when youexecute the command; if the switching succeeds, your user level on the management device isretained.z If the Telnet users on the device to be logged in reach the maximum number, the switching fails.z To prevent resource waste, avoid ring switching when configuring access between clustermembers. For example, if you switch from the operation interface of the management device to thatof a member device and then need to switch back to that of the management device, use the quitcommand to end the switching, but not the cluster switch-to administrator command to switch tothe operation interface of the management device.Adding a Candidate Device to a ClusterFollow these steps to add a candidate device to a cluster:To do… Use the command… RemarksEnter system view system-view —Enter cluster view cluster —
