6.1 Introduction to cluster network management
Cluster network management is an in-band configuration management. Unlike CLI, SNMP and Web Config
which implement a direct management of the target switches through a management workstation, cluster
network management implements a direct management of the target switches (member switches) through an
intermediate XGS3-42000R(commander s witch). A commander switch can manage multiple member
switches. As soon as a Public IP address is configured in the commander switch, all the member switches
which are configured with private IP addresses can be managed remotely. This feature economizes public IP
addresses which are short of supply. Cluster network management can dynamic ally discover cluster feature
enabled switches (candidate switches). Network administrators can statically or dynamically add the
candidate switches to the cluster which is already established. Accordingly, they can configure and manage
the member switches through the commander switch. When the member switches are distributed in various
physical locations (such as on the different floors of the same building), cluster network management has
obvious advantages. Moreover, cluster network management is an in-band management. The c ommander
switch can communicate with member s witches in existing network. There is no need to build a specific
network for network management.
Cluster network management has the following features:
Save IP addresses
Simplify configuration tasks
Indifference to network topology and distance limitation
Auto detecting and auto establishing
With factory default settings, multiple switches can be managed through cluster network management
The commander switch can upgrade and configure any member switches in the cluster
6.2 Cluster Network Management Configuration Sequence
Cluster Network Management Configuration Sequence:
1． Enable or disable cluster function
2． Create cluster
1) Configure privat e IP address pool for member switches of the cluster
2) Create or delete cluster
3) Add or remove a member switch
3． Configure attributes of the cluster in the commander switch
1) Enable or disable automatically adding cluster members
2) Set automatically added members to manually added ones
3) Set or modify the time interval of keep-alive messages on switches in the cluster.
4) Set or modify the max number of lost keep-alive messages that can be tolerated
5) Clear the list of candidat e switches maintained by the switch
4． Configure attributes of the cluster in the candidate switch
1) Set the time interval of keep-alive messages of the cluster
2) Set the max number of lost keep-alive messages that can be tolerated in the cluster
