Configuring Topology Management
The concepts of blacklist and whitelist are used for topology management. An administrator can
diagnose the network by comparing the current topology (namely, the information of a node and its
neighbors in the cluster) and the standard topology.
z Topology management whitelist (standard topology): A whitelist is a list of topology information that
has been confirmed by the administrator as correct. You can get the information of a node and its
neighbors from the current topology. Based on the information, you can manage and maintain the
whitelist by adding, deleting or modifying a node.
z Topology management blacklist: Devices in a blacklist are not allowed to join a cluster. A blacklist
contains the MAC addresses of devices. If a blacklisted device is connected to a network through
another device not included in the blacklist, the MAC address and access port of the latter are also
included in the blacklist. The candidate devices in a blacklist can be added to a cluster only if the
administrator manually removes them from the list.
The whitelist and blacklist are mutually exclusive. A whitelist member cannot be a blacklist member, and
vice versa. However, a topology node can belong to neither the whitelist nor the blacklist. Nodes of this
type 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 whitelist
and 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 is
re-established, you can choose whether to restore the whitelist and blacklist from the Flash
automatically, or you can manually restore them from the Flash of the management device.
