1-15Configuring Topology ManagementThe concepts of blacklist and whitelist are used for topology management. An administrator candiagnose the network by comparing the current topology (namely, the information of a node and itsneighbors in the cluster) and the standard topology.z Topology management whitelist (standard topology): A whitelist is a list of topology information thathas been confirmed by the administrator as correct. You can get the information of a node and itsneighbors from the current topology. Based on the information, you can manage and maintain thewhitelist by adding, deleting or modifying a node.z Topology management blacklist: Devices in a blacklist are not allowed to join a cluster. A blacklistcontains the MAC addresses of devices. If a blacklisted device is connected to a network throughanother device not included in the blacklist, the MAC address and access port of the latter are alsoincluded in the blacklist. The candidate devices in a blacklist can be added to a cluster only if theadministrator manually removes them from the list.The whitelist and blacklist are mutually exclusive. A whitelist member cannot be a blacklist member, andvice versa. However, a topology node can belong to neither the whitelist nor the blacklist. Nodes of thistype are usually newly added nodes, whose identities are to be confirmed by the administrator.You can back up and restore the whitelist in the following two ways:z Backing them up on the FTP server shared by the cluster. You can manually restore the whitelistand blacklist from the FTP server.z Backing them up in the Flash of the management device. When the management device restarts,the whitelist and blacklist will be automatically restored from the Flash. When a cluster isre-established, you can choose whether to restore the whitelist and blacklist from the Flashautomatically, or you can manually restore them from the Flash of the management device.Follow these steps to configure cluster topology management:To do… Use the command… RemarksEnter system view system-view —Enter cluster view cluster —Add a device to the blacklist black-list add-macmac-address OptionalRemove a device from theblacklistblack-list delete-mac { all |mac-address } OptionalConfirm the current topologyand save it as the standardtopologytopology accept { all [ save-to{ ftp-server | local-flash } ] |mac-address mac-address |member-id member-number }OptionalSave the standard topology tothe FTP server or the localFlashtopology save-to { ftp-server |local-flash } OptionalRestore the standard topologyinformationtopology restore-from{ ftp-server | local-flash } OptionalConfiguring Interaction for a ClusterAfter establishing a cluster, you can configure FTP/TFTP server, NM host and log host for the cluster on
