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: Switches in a blacklist are not allowed to join a cluster. A blacklist
contains the MAC addresses of switches. If a blacklisted switch is connected to a network through
another switch not included in the blacklist, the MAC address and access port of the latter are also
included in the blacklist. The candidate switches 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
the blacklist member cannot be a whitelist member. 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 two 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 switch. When the management switch 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 switch.

Configuring interaction for a cluster
After establishing a cluster, you can configure FTP/TFTP server, NM host and log host for the cluster on
the management switch.
•
After you configure an FTP/TFTP server for a cluster, the members in the cluster access the FTP/TFTP
server configured through the management switch. Execute the
ftp
server-address
or
tftp
server-address
command and specifying the private IP address of the management switch as the
server-address
. For more information about the
ftp
and
tftp
commands, see

After you configure a log host for a cluster, all the log information of the members in the cluster will
be output to the configured log host in the following way:
