Chapter 8 Network Management
Cluster Management
Cluster Management Overview
ZGMP is ZTE Group Manage Protocol. A 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.
The 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 con-
figured with a public network IP address. A private address is allo-
cated 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 that you isolate the broadcast domain between
the public network and the private network on the command switch
and shield direct access to the private address. The command
switch provides an external management and maintenance chan-
nel to manage the cluster in a centralized manner.
In general, the 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. The command switch
can automatically collect the device topology and set up a cluster.
After a cluster is set up, the command switch provides a clus-
ter management channel to manage member switches. Member
switches serve as candidate switches before they join the cluster.
The switches that do not support cluster management are called
independent switches.
