Cluster Feature
The Model 3124 supports Cluster feature that can make a group of NEs (network elements) work together as
a single NE from the management point of view. Operators can manage the NEs in a cluster, called cluster
nodes, via the same single IP address in terms of CLI, Web-based GUI or SNMP based management inter

faces. The Model 3124 currently provides cluster feature that a cluster can include up to four cluster members
(NEs). There are one Master and the other members are all Slaves in a cluster. The Master works as a gateway
of the Slaves, and it also can forward CLI/Web/SNMP commands to the destination Slave. The Slaves can exe

cute the commands and respond to the Master.
It uses star topology for conducting a Clustering Management group.

Before you group a Master and a Slave IPDSLAM, some parameters need to be well configured:
1. Cluster domain name: The group name for a cluster must be the same on Master and Slave.
2. Cluster IP address: IP address to be used for remote management when Master and Slave are grouped
together.
3. NE cluster name: A name to identify Master or Slave.
4. Set private IP address on in-band port for both Master and Slave IPDSLAM. The private IP is used for
communication between Master and Slave. The management center actually uses Cluster IP address for
remote management.
5. Master and Slave need to be configured with same management VLAN.
6. The default gateway should be configured to the router that is aware how to route management traffic to
Management Center of the management network. The setting of Cluster default gateway should be the
same between Master and Slave.
