179• Topology management whitelist (standard topology): A whitelist is a list of topology informationthat has been confirmed by the administrator as correct. You can get the information of a node andits neighbors from the current topology. Based on the information, you can manage and maintainthe whitelist by adding, deleting or modifying a node.• Topology management blacklist: Switches in a blacklist are not allowed to join a cluster. A blacklistcontains the MAC addresses of switches. If a blacklisted switch is connected to a network throughanother switch not included in the blacklist, the MAC address and access port of the latter are alsoincluded in the blacklist. The candidate switches 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, andthe blacklist member cannot be a whitelist member. However, a topology node can belong to neither thewhitelist nor the blacklist. Nodes of this type are usually newly added nodes, whose identities are to beconfirmed by the administrator.You can back up and restore the whitelist and blacklist in the following two ways:• Backing them up on the FTP server shared by the cluster. You can manually restore the whitelist andblacklist from the FTP server.• Backing them up in the Flash of the management switch. When the management switch restarts, thewhitelist and blacklist will be automatically restored from the Flash. When a cluster is re-established,you can choose whether to restore the whitelist and blacklist from the Flash automatically, or youcan manually restore them from the Flash of the management switch.Follow these steps to configure cluster topology management:To do… Use the command… RemarksEnter system view system-view —Enter cluster view cluster —Add a switch to the blacklist black-list add-mac mac-address OptionalRemove a switch from the blacklist black-list delete-mac { all | mac-address } OptionalConfirm the current topology andsave it as the standard topologytopology accept { all [ save-to { ftp-server |local-flash } ] | mac-address mac-address |member-id member-number }OptionalSave the standard topology to theFTP server or the local Flash topology save-to { ftp-server | local-flash } OptionalRestore the standard topologyinformation topology 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 onthe management switch.• After you configure an FTP/TFTP server for a cluster, the members in the cluster access the FTP/TFTPserver configured through the management switch. Execute the ftp server-address or tftpserver-address command and specifying the private IP address of the management switch as theserver-address. For more information about the ftp and tftp commands, see FundamentalsCommand Reference.• After you configure a log host for a cluster, all the log information of the members in the cluster willbe output to the configured log host in the following way:
