The concepts of blacklist and whitelist are used for topology management. An
administrator can diagnose the network by comparing the current topology and
the standard topology.
Current topology: The information of a node and its neighbors of the cluster.
■
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.
Topology management blacklist: A blacklist is a list of devices that are not
■
allowed to join a cluster unless the administrator manually removes them from
the list. A blacklist contains the MAC addresses of devices. If a blacklist device
is connected to network through another device not included in the blacklist,
the MAC address and access port of the latter are also included in the blacklist.
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 the whitelist and blacklist to prevent them from missing when a
power failure occurs to the management device. The following two backup and
restore mechanisms are available:
Backing them up on the FTP server shared by the cluster. You can manually
■
restore the whitelist and blacklist from the FTP server.
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 reestablished, 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.
Follow these steps to configure cluster topology management:
