Cluster Management Overview
Cluster is a combination consisting of a set of switches in a
specific broadcast domain. This set of switches forms a unified
management domain, providing an external public network IP
address and management interface, as well as the ability to
manage and access each member in the cluster.
Management switch which is configured with a public network IP
address is called a command switch. Other switches serve as
member switches. In normal cases, a member switch is not
configured with a public network IP address. A private address
is allocated to each member switch through the class DHCP
function of the command switch. The command switch and
member switches form a cluster (private network).
It is recommended to isolate broadcast domain between public
network and private network on the command switch and shield
direct access to private address. Command switch provides an
external management and maintenance channel to manage
cluster in a centralized manner.
In general, broadcast domain where a cluster is located consists
of switches in these roles: Command switch, member switches,
candidate switches and independent switches.
One cluster has only one command switch. Command switch
can automatically collect device topology and set up a cluster.
After a cluster is set up, the command switch provides a cluster
management channel to manage member switches. Member
switches serve as candidate switches before they join the cluster.
Switches that do not support cluster management are called
independent switches.
Cluster management networking is shown in
Figure 42.
