Introduction to the Newly Added Cluster Functions 385
■ Configuring topology management
Topology management is performed based on white list and blacklist. The meanings
of white list and blacklist are as follows:
■ White list: Correct network topology confirmed by the network administrator.
You can obtain topology node information and neighboring relationship at this
moment from the current network topology. Meanwhile, you can maintain the
white list based on the current topology, such as adding a node, deleting a
node, and modifying a node.
■ Blacklist: Members in the blacklist are not allowed to join the cluster
automatically. The network administrator needs to add a member in the black
list into the cluster, including the MAC address of the device. After the device is
added into the blacklist, if it connects to the network through a non-blacklist
device, the information and the access port of the non-blacklist device will be
added into related entries of the management device.
White list and blacklist are exclusive. Nodes in the white list are not in the blacklist.
Nodes in the black list cannot be added into the white list. Topology nodes are
located neither in the white list nor in the blacklist. This kind of nodes is newly-added
nodes, which are not confirmed by the network administrator.
White list and black list are saved in the flash of the management device. They still
exist after the management device is powered off. You need to resume the white list
and the black list manually. When you restart the management device or rebuild the
cluster, the white list and the blacklist can be resumed from the flash. t
Reboot the specified
member device
reboot member {
member-number |
mac-address mac-address }
[ eraseflash ]
Optional
Locate a device with
the MAC address or
the IP address
tracemac { by-mac
mac-address vlan vlan-id |
by-ip ip-address }
[ nondp ]
Optional
You can execute this command
according to the MAC table saved
by the device. If there is no
required VLAN ID, you cannot
execute this command
Exit cluster view quit -
Exit system view quit -
Switch between the
management device
and a member device
to perform
configuration
cluster switch-to {
member-number |
mac-address mac-address |
administrator }
Optional
Currently, before executing this
command, you must enable telnet
server on the opposite device and
ring switching is not allowed
