Introduction to the
Newly Added Cluster
Functions
The newly added cluster functions aim to improve switch performance. They extend
switch functionality.
With the cluster function employed, you can manage and maintain all the member
switches in a cluster through the master switch. (A cluster can contain up to 16
switches.)
The newly added cluster functions include:
■
SNMP configuration synchronization of the member devices passing topological
authentication
■
lUser name and the corresponding password synchronization of Web users
■
Black/white list and topological authentication
■
TRACE MAC function
■
Upgrading software of the member devices in a cluster through Web
■
Member device configuration backup/restoration through Web
These functions enrich the Ethernet switch cluster management technology and
significantly relieve network administration workload. They also provide common
users with a simple and intuitive way for managing switch clusters.
Notes
■
You need to enable the cluster function before configuring any of the newly
added cluster functions.
■
To employ the newly added cluster functions, you need to enable the cluster
function and perform other related configurations on the master device. As for the
member devices and the candidate devices, you only need to enable the cluster
function for them so that they are under the management of the master device.
■
For the configurations of the last two functions listed above, see your Web user
manual.
