Cluster Management
Overview
Cluster is a combination of a group of switches in a specific broad-
cast domain. This group of switches forms a unified management
domain which provides a public network IP address and a man-
agement interface to the outside and provides the functions of
managing and accessing every member in the cluster.
The management switch which configures public network IP ad-
dress is called command switch and other managed switches are
called member switches. Generally, public network IP address is
not configured for the member switch but a private address is as-
signed to the member switch with similar DHCP function of the
command switch. Command switch and member switch form a
cluster (private network).
It is suggested to isolate the broadcast domain of the public net-
work and that of the private network on the command switch,
and shield the direct access to the private address. The command
switch provides a management and maintenance channel to the
outside to manage the cluster in a centralized and unified manner.
A broadcast domain is usually composed of four kinds of switches:
command switch, member switch, candidate switch and indepen-
dent switch.
There is only one command switch in a cluster. Command switch
can collect equipment topology and establish a cluster automati-
cally. After the cluster is established, command switch provides a
management channel for cluster to manage member switch. Mem-
ber switch serves as a candidate switch before being added into
cluster. Switch which does not support cluster management is
called independent switch.
