Example for Outputting Information to an SNMP Agent

After information is output to an SNMP agent, the NMS can receive the information from the Device through an SNMP agent.

Networking Requirements

On the network shown in Figure 1, a Device is connected to the NMS. To monitor the Device operation in real time or collect important information about the Device operation, you can output traps to an SNMP agent. The SNMP agent forwards the information to an NMS.

In this example, traps are output to a remote terminal.

Figure 1 Outputting traps to an SNMP agent

Interfaces 1 in this example are GE 0/1/0.

Configuration Roadmap

The configuration roadmap is as follows:

Enable the information management function.
Configure the channel through which traps are output to an SNMP agent and the module of which traps are to be output.
Output traps to the SNMP agent.
Output traps to an NMS through an SNMP agent.

Data Preparation

To complete the configuration, you need the following data:

Information channel number
Module and severity of the traps to be output

Procedure

Configure available routes between the router and the NMSs. Details for the configuration procedure are not provided here.

Enable the information management function.

<HUAWEI> system-view

Configure the channel through which traps are output to an SNMP agent and the module of which traps are to be output.
# Output traps whose severity is informational or higher to channel 7.
```
[*Device] info-center source im channel channel7 trap level informational
```

Output traps to an SNMP agent.

[*Device] info-center snmp channel channel7

Output traps to the NMS through an SNMP agent.

# Enable the SNMP agent function, with the SNMP version of SNMPv2c.

[*Device] snmp-agent sys-info version v2c

# Enable the SNMP agent to send traps.

[*Device] snmp-agent trap enable
[*Device] snmp-agent target-host trap address udp-domain 10.1.1.1 params securityname public

Verify the configuration.

# Display the channel used by the SNMP agent to output traps.
