Configuring Topology Management - H3C S3610 Series Operation Manual

its super password is synchronized to that of the management device
automatically. After a cluster is created, you are recommended not to modify the
super passwords of both the cluster members and the management device for
fear of switching failures.
After you switch from the management device to a member device, the user level
on the member device inherits that of the management device.
When you switch from a member device to the management device, the user level
is determined by the predefined setting on the management device.
You will fail to switch to a device if the number of the Telnet users on the device to
be accessed reaches the upper limit.
Avoid ring switching to prevent performance degrading. For example, if you switch
from the management device to a member device, and then want to switch back to
the management device, execute the quit command instead of the cluster
switch-to administrator command.

1.3.8 Configuring Topology Management

The concepts of blacklist and whitelist are used for topology management.
A whitelist is a list of devices that have been confirmed by the administrator as
adequate in the topology. 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 blacklist by adding, deleting or modifying a node.
A blacklist is a list of devices that are not allowed to join a cluster unless the
administrator manually removes them from the list. In the 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 is 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. This type of nodes is usually
newly added nodes, whose identity are to be confirmed by the administrator.
The whitelist and blacklist do not lost when a power failure occurs to the management
device. They are stored in the FTP server or the flash of the management device and
can be restored when necessary. When the management restarts or a cluster rebuilds,
the whitelist and blacklist will be automatically restored from the flash.
