Configuring topology management

The concepts of blacklist and whitelist are used for topology management. An administrator can
diagnose the network by comparing the following topologies: current topology —the information of a
node and its neighbors in the cluster—and the standard topology.
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—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 only be added to a cluster 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 and blacklist in the following ways:
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 re-established,
choose whether to restore the whitelist and blacklist from the Flash automatically, or manually restore
them from the Flash of the management device.
To configure cluster topology management:
To do...
1. Enter system view.
2. Enter cluster view.
3. Add a device to the blacklist.
4. Remove a device from the
blacklist.
Use the command...
system-view
cluster
administrator-address mac-
address name name
Use the command...
system-view
cluster
black-list add-mac mac-address
black-list delete-mac { all | mac-
address }
