Introduction

This document provides UniSystem Simple Network Management Protocol (UniSystem SNMP) configuration examples.

	NOTE: Starting from version 2.59, FIST software has been renamed as UniSystem.

 

Prerequisites

Procedures and information in the examples might be slightly different depending on the software or hardware version of the products.

The configuration was created and verified in a lab environment, and all the servers and software were started with the factory default configuration. If the device has been configured, ensure that the existing configuration does not conflict with the configuration in the following example.

The following information is provided based on the assumption that you have basic knowledge of the SNMP alarm forwarding feature of UniSystem.

Configuration example

 

NOTE: ·     The configuration procedure is the same for SNMPv1 and SNMPv2c. This example uses SNMPv2c. ·     The configuration procedure is not the same for SNMPv3 and SNMPv2c. This document will introduce the different parts of the two, and will not describe the same or similar parts of the two.

 

Network configuration

As shown in Figure 1, the UniSystem server (acting as the SNMP agent) is connected to UniSystem-managed Server A and Server B, and the PC with management software installed (acting as SNMP NMS) through a switch. All of them can communicate with each other. The SNMP NMS uses SNMP to manage the agent (UniSystem server), and the UniSystem server automatically sends an alarm to the NMS in case of Server A failure or Server B failure.

·     UniSystem management IP addresses: 192.168.0.12/16

·     Server HDM management IP addresses:192.168.49.51/16, 192.168.47.51/16

·     IP addresses of the PC with MibBrowser: 192.168.0.235/16

Analysis

1.     Prepare the NMS network management software for receiving trap messages.

2.     By configuring SNMP on UniSystem, the NMS software can receive the trap alarm information from UniSystem so that UniSystem can forward the server's alarm trap to the specified destination.

Software versions used

This example was created and verified on UniSystem-2.42.

Restrictions and guidelines

·     For the NMS to receive the alarm information of the agent, the SNMP version number and community name on the agent and the NMS must match.

·     The NMS software configuration varies by vendor. For information about configuring the NMS, see the NMS manual.

·     Only when the UniSystem listening setting is enabled can the UniSystem server receive traps sent from managed servers.

·     If you have set the alarm level in the HDM, the UniSystem SNMP filters the alarms based on the set alarm level (the level of alarms forwarded by UniSystem is higher than or equal to the level set in the HDM).

Procedures

Add the servers to UniSystem.

1.     Open the browser of the UniSystem client, enter the system IP 192.168.0.12 of the UniSystem server in the address bar, and press Enter to access the UniSystem login page, as shown in Figure 2.

2.     On the login page, enter the username (admin by default) and password (Password@_ by default), and then click Log In.

3.     Click Menu > Devices > Server List. On the server list page that opens, click Add. In the Method dialog box, select a server addition method, as shown in Figure 3.

4.     Three methods are available. In this example, Add manually is selected. Click Add manually. In the dialog box that opens, add the server information of the two servers to be added, as shown in Figure 4.

Figure 4 Manually adding the server

 

¡     Server Type: Select HDM.

¡     IP Address: Specify the HDM IP address of the server to be added, which is 192.168.49.51.

¡     Username: Specify the HDM login username of the server to be added, which is admin.

¡     Password: Specify the HDM password of the server to be added, which is Password@_.

¡     Device Name: Specify the name of the server to be displayed on UniSystem. This parameter is optional.

Add another server in the same way.

 

NOTE: If more than three servers need to be added, select a method based on the actual requirements.

 

Enabling the listening function

1.     Click Menu > Monitor > Alarm Forwarding to enter the page as shown in Figure 5.

2.     Click Configure in the Listening Settings column. In the dialog box that opens, configure the following settings, as shown in Figure 6.

¡     Listening Settings: Select On.

¡     Listening IP: Specify the IP address of the UniSystem server.

¡     Listening Port: Enter 161. (Specify the port that is not occupied while UniSystem is running, with a port range of 1 to 65535. If the port is occupied, UniSystem will report an error)

3.     Click OK.

Configuring SNMP (SNMPv2c)

1.     Click Menu > Monitor > Alarm Forwarding. On the alarm forwarding page, click the SNMP Settings tab to enter the page as shown in Figure 7.

2.     Click Add Trap Destination. In the dialog box that opens, configure the following settings, as shown in Figure 8.

¡     Destination IP: Specify 192.168.0.235 (The IP address of NMS. If NMS is installed on a local PC, the destination IP is the local PC IP)

¡     Destination Port: Specify 162 (the default SNMP trap service port).

¡     Version: Select v2c.

¡     Community: Specify public.

¡     Output Trap Level: Select Info (This level is used for UniSystem filtering the message level sent by HDM, not to set the output trap level of HDM).

3.     After configuring the trap destination, click OK and the configuration of the SNMP v2c trap alarm forwarding is complete, as shown in Figure 9.
