Cluster Management

Cluster refers to an aggregation formed by a group of switch in a particular broadcasting
domain. This group of switch composes a unified management domain, providing a
public IP address and management interface outside. Also it offers management and
access capability to each member in the cluster.
The management switch responsible for configuring public IP address is called command
switch, and other managed switches are named member switch. Normally, the member
switch does not have public IP addresses, instead it uses DHCP-similar service of the
command switch to distribute private address. The command switch and member switch
compose cluster together (Private Network)
The isolation of broadcasting domain between public network and private network is
proposed to be done on the command switch. Isolating the direct access to the private
address, the command switch provides a management maintenance tunnel outside to
implement integrated cluster management.
The broadcasting domain of one cluster is normally composed by four roles of switch:
command switch, member switch, candidate switch and independent switch.
There's only one command switch in one cluster. The command switch can collect
equipment topology automatically, and set up cluster. After building the cluster, the
command switch provides a management tunnel for the cluster to manage the member
switch. Before joining in the cluster, the member switch is the candidate switch. And the
switch that does not support cluster management is called the independent switch.
Cluster management networking is as shown in the following Figure:
