Introduction of SNMPc and NetAtlas
With the number of network device increase, the demand to detect and respond to the
network failure or external event in a very short time posts a great challenge to network
administrator. How to easily manage and monitor network devices across networks
becomes more and more important in network management.
Figure 1 presents main elements of the system architecture. Element Management
System (EMS), NetAtlas provides a centralized remote management platform and acts
as SNMPc manager to perform network configuration, system management,
event/alarm management, performance management and security for all ZyXEL’s
Ethernet Switch solutions. SNMPc is network management software produced by
Castle Rock that constantly probe the network element (NE) and collect information of
those NE for EMS. Underneath the EMS is Postgres SQL, the enterprise relational
database system, provides query for EMS

Configuration of adding a new device via SNMPc
In the following example, we will illustrate how to get started with SNMPc and Netatlas
with adding a new device. Follow the procedures from Step 1 to Step 11.
Step 1: In the edit button bar shown in the Figure 4 where you may select the icon to
insert a new element.
Figure 4 Adding a new Device
Step 2: In the map object properties, give the label name and enter the IP address of
the selected device. In this example, we configure 172.23.3.11 as its IP address of
ES-2108 as shown in Figure 5
