Querying SNMP Information

Querying SNMP Information

This section describes the software for querying ES3000 V3 SNMP information and where to obtain the software.

Using the Net-SNMP Command Set

You need to install net-snmp-utils before using the Net-SNMP command set to query ES3000 V3 SNMP information. You can use the Linux Net-SNMP tool package.

For details about how to use the Net-SNMP command set, see http://www.net-snmp.org.

Using a MIB Browser

You can use a management information base (MIB) browser to query SNMP information. Multiple MIB browsers are available. The MG-SOFT MIB browser is recommended. The browser is a Windows graphical user interface (GUI) tool with the trap receiving function.

For details about how to download and use the MG-SOFT MIB browser, see http://software.informer.com.

Common Problems

  1. SELinux may forbid Net-SNMP from accessing SSDs (/dev/nvme*) and cause the ES3000 V3 SNMP module to function abnormally, so you need to change the SELinux rights configuration.
  2. The firewall may cause failure to obtain SNMP and device information within the Intranet. If the failure occurs, disable the firewall or modify the firewall settings.
  3. Before starting Net-SNMP, you can run the following command to check whether the snmpd.conf file is loaded properly. If the file is not installed properly, the command output reports an error.
    #snmpd –Dread_config –H 2>&1 | grep "Reading" | sort -u

Example

If Net-SNMP 5.7 is used, use the snmpd.conf file provided by the ES3000 V3 to start the snmpd program.

snmpd –d –Lo –c /opt/hio/snmpd.conf

Use the snmpwalk command tool to query ES3000 V3 through SNMP v2c.

snmpwalk -v 2c -c public localhost enterprises.2011.2.319

Or query through SNMP v3.

snmpwalk -v3 -u v3user -l auth -a MD5 -A Huawei123#$ 127.0.0.1 enterprises.2011.2.319

The following command output is an example:

# snmpwalk -Os -c public -v2c 127.0.0.1 enterprises.2011.2.319 -m ./HW-ES3000V3-MIB.my
