Introduction

The following information describes Simple Network Management Protocol (SNMP) configuration examples.

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. When you are working on a live network, make sure you understand the potential impact of every command on your network.

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

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 requirement

As shown in Figure 1, the ManageEngine MibBrowser 5 is installed on the PC to act as the management software of the SNMP Network Management System (NMS). The NMS uses SNMP to manage the agent (uses the R4900 G5 server as an example), and the agent automatically sends an alarm to the NMS in case of exceptions.

Figure 1 SNMP Network diagram

 

Software versions used

This example was created and verified on HDM 2.32.

Restrictions and guidelines

·     For the NMS to manage and maintain 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.

Procedures (SNMPv1/SNMPv2c)

Configuring the agent

Enter the HDM SNMP configuration screen

1.     Open the browser on the server client, and enter the server's HDM management IP 10.99.205.138 in the address bar, as shown in Figure 2. On the login page, enter the default username admin and the default password Password@_, and then click Sign In.

Figure 2 HDM Web login page

 

2.     Click Remote Services > SNMP. On the SNMP configuration page, configure the following settings as shown in Figure 3, and then click Save.

¡     SNMP version: v2c

¡     Long community string: Disable

¡     Read-only community string: public

¡     Confirm the read-only community string: public

¡     Read/write community string: private

¡     Confirm the read/write community: private

Configure SNMP trap settings

1.     Click Remote O&M > Alarm Settings > SNMP trap. On the SNMP trap configuration page, configure the following settings as shown in Figure 4, and then click OK.

¡     SNMP trap: Enable

¡     SNMP trap mode: Event mode (recommended)

¡     SNMP version: v2c

¡     Trap community: public

¡     Alarm sending level: All

2.     Configure the target address of trap alarms.

Click Remote O&M > Alarm Settings > SNMP trap. On the SNMP trap configuration page, click Edit in a server entry. In the dialog box that opens, configure the following settings as shown in Figure 5, and then click OK.

¡     Status: enabled

¡     Server address: 10.99.120.117

¡     Server port: 162

Figure 5 Editing trap server settings

 

After the configuration is complete, click Test in the Actions column for an alarm trap server. If a prompt displaying You have sent the test alarm successfully, it indicates the settings are successfully configured.

 

Power on the server

Click System > Power Management > Power Management to view the current power status, as shown in Figure 6.

If the server is not in the Power on status, the system can not read the information of some branch nodes. If it is in the Power on status, you do not need to perform this task.

Figure 6 Power on the server

 

Configuring the NMS

Obtain the MIB file

The MIB file of the HDM version is released with the version. To get the MIB file, open a browser, access H3C's official website, and navigate to Support > Resource Center > Software Download > Servers. Select a product to navigate to the firmware download page, select the target HDM version, and download the target MIB file.

 

Load MIB files

1.     Open the management software ManageEngine MibBrowser 5 of the NMS, as shown in Figure 7.

Figure 7 Opening the management software

 

2.     From the menu of the NMS management software, select File > Load Mib, select all files with the suffix mib in the decompressed folder MIB > HH3C > MIB Files, and then click Open, as shown in Figure 8.

Figure 8 Load MIB files

 

3.     After the files are loaded, three items with the prefix HH3C are displayed under the Loaded MibModules box on the left of the SNMP NMS management software, as shown in Figure 9.

Configure the SNMP NMS management software parameters

1.     Configure related parameters in SNMP NMS, as shown in Figure 10.

¡     Host: 10.99.205.138

¡     Port: 161

¡     Community: public

¡     Write Community: private

2.     From the menu of the SNMP NMS management software, select Edit > Settings. On the settings page that opens, select v2c for SNMP Version, keep the default settings for other parameters, as shown in Figure 11, and then click OK.

Get the server information through the management software (Get)

In the SNMP NMS management software, click HH3C-SERVER-AGENT-MIB to expand the file, select a node to be read, and right-click the mouse. In the dialog box that opens, select GET to read the MIB node information.

This section describes how to get the information of the node named hh3cSrvLdapEnable. This node indicates the enabling status of the LDAP service on the server. hh3cSrvLdapEnable.0 under the blue text on the lower right part of the management software indicates the information that has been read, and Disable(0) indicates that the LDAP service is not enabled, as shown in Figure 12.

Set the server information through the management software (Set)

1.     As shown in Figure 12, select node hh3cSrvLdapEnable, and enter 1 in the Set Value field, which indicates that the value of hh3cSrvLdapEnable is set to enable(1).

2.     Right-click the hh3cSrvLdapEnable node. In the dialog box that opens, select SET to set the MIB node information, as shown in Figure 13.

Verifying the configuration

View the GET result

If the hh3cSrvLdapEnable information got through NMS is 0 and the LDAP settings status is Disable on the HDM page, it indicates that the configuration has taken effect.

View the SET result

If the hh3cSrvLdapEnable information set through NMS is 1 and the LDAP settings status is Enable on the HDM page, as shown in Figure 20, it indicates that the configuration has taken effect.

View the trap result

1.     After you finish the above trap settings, the server will send trap information to the NMS if you unplug a power supply on a server with multiple power supplies connected. On the TrapViewer section of the SNMP NMS management software, you can view the trap alarm information sent by HDM, as shown in Figure 21.
