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

5. Netatlas comes with a feature called “Auto Discovery”, if you are not going to use

this “Auto Discovery” at this time, check the box “Start with Discovery off”. Then click

“Next”

NetAtlas Support Notes

6. Here it shows the default program folder that Netatlas is going to install. Click “Next”

to continue.

At this moment, the installation of SNMPc is completed.

7. If PostgreSQL does not exist in your PC, the Netatlas installation program will also

install it for you.

Overview of SNMPc

The following diagram shows the main elements of SNMPc. SNMPc includes the

following function

♦ Main Button Bar: Button and controls to execute commands quickly

♦ Edit Button Bar: Button to quickly insert map element

♦ Event Log Tool: Button display filtered event log entries

♦ View Window Area: Map View, Mib Tables and Mib Graph windows are displayed

here.

♦ View Window Area: Map View, Mib Tables and Mib Graph windows.

Overview of EMS

The following diagram illustrates the main elements in EMS. EMS contains the four

main functions.

♦ Menu Shortcut Bar: The buttons execute common commands

♦ Device Panel: This is a graphical device display.

♦ Device List Panel: View devices in a tree structure. The colors of the device

indicate the status of the devices. Green is working and Rd is no response from

the device.

♦ System message Panel: View the alarm Status and port status of the selected

switch.

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

Add 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

Figure 5 Map Object Properties

NetAtlas Support Notes

Step 4: In the map object properties, select Access tab to set the parameters of Read

Access Mode to SNMP V2c shown in Figure 6. Change the value of Read Access

Mode to SNMP V2c.

Figure 6 Read Access mode

NetAtlas Support Notes

Step 5: In the map object properties, select Access tab to set the parameters of Read

/Write Access Mode to SNMP V2c shown in Figure 7. Change the value of Read/write

Access Mode to SNMP V2c.

Figure 7 Read/Write Access Mode

Step 6: In the map object properties, select Access tab to set the parameters of Read

community to public as shown in Figure 8.

Figure 8 Read Community

NetAtlas Support Notes

In the map object propeies, select Access tab to set the parameters of Read

community to public in Figure 9. Change the value of Read//write Community to Public.

Step 7: On the SNMPc main window. Select SNMPc->Config->MIB Database menu

function. You need to add (and compile) the following Mib files in order:

9 rfc2674.mib 9 rfc2925.mib 9 rfc3291.mib 9 rfc3621.mib 9 OSPF-MIB.mib 9 zyxel-ES3124.mib 9 zyxel-ES3124PWR.mib 9 zyxel-ES2024A.mib 9 zyxel-GS2024.mib 9 zyxel-GS4024.mib 9 zyxel-GS4012F.mib 9 zyxel-ES2108.mib 9 zyxel-ES2108G.mib

Step 8: In the Selection tool menu, Click ES-2108 to manage the device.

Figure 10 Device Selection

NetAtlas Support Notes

Step 9: After the selection, a pop-up menu will display the NetAtlas switch manager

diagram. Click the Switch Manager to enter the EMS Mapping shown in Figure 11

Figure 11 Device Selection

Step 10: In the EMS mapping, it display a logical hierarchy for the device. In the device

list, you may see the devices are added in the Rootmap shown in Figure 12.

VLAN Configuration via EMS

In this section, we will give an example to illustrate how to use EMS to create a VLAN2

in GS-4024. Here are the procedures.

Step 1: In the device panel list shown in Figure 12, right-click Configuration, Switch

Configuration and then Switch Setup tab as shown in Figure 12 and Figure 13.

Step 2: Define the VLAN type, there are two types of VLAN, one is 802.1Q and the

other is Port-based VLAN. Select 802.1Q as the VLAN type and click Apply in the

Figure 14.

After the VLAN type selection, a pop-up window indicates that you have finished the

configuration. Then after we have defined the VLAN type to be the 802.1Q, go back to

click the Configuration and then VLAN configuration in Figure 15.

Troubleshooting

Question: SNMPc, EMS and/or PostgreSQL will not install properly.

Answer:

• Make sure that the computer on which you want to install the SNMPc, EMS and

PostgreSQL meets the minimum hardware and software requirements.

• To install PostgreSQL, make sure your computer is using NTFS file system.

• Shut down any running services or applications which may affect the installation.

• Remove any previous versions of PostgreSQL and SNMP software from your

computer.

• Re-install SNMPc and EMS in that order.

Question: I cannot find my device in the SNMPc Management screen.

Answer:

• Check that you have added and compiled the MIBs correctly. Make sure that the

orders are followed exactly.

• Check that you have enabled auto-discovery;

• Check that the map object properties are correct for initial installation; Make sure the

IP address entered is the IP address of the switch you want to manage via the EMS.

• Check that the ODBC driver is correctly configured;

• Make sure that PostgreSQL is running.

• Make sure that the computer you have installed the EMS on, is connected to the

network where the switch is located.

• Make sure your computer’s Ethernet card is working properly.

• If the problem still persists, uninstall and re-install the EMS software.
