Simple Network Management Protocol (SNMP) is an application–layer protocol, which is used to manage and monitor network elements and exchange management information between network devices. By default SNMP uses port 161 for communication.

Since the inception SNMP, it embraces three versions: v1, v2c and v3. V1 and v2c are the most implemented version of SNMP; v3 is target at the high security when compare to its older versions. The gateway support private SNMP MIBs (private enterprise number) to access.

A powerful, indispensable and easy-to-use MIB browser is convenient for engineer/manager to manage SNMP enabled network devices and applications. In this session, Manage Engine MIB browser is selected. It allows user to issue SNMP requests to retrieve agent’s data, or make changes to the agent. It is free tool for Windows, Mac and Linux.

(1). Get SNMP parameters via SNMP MIB browser. It’s supposed that Manage Engine MIB browser is installed perfectly. Figure 2 is the main interface of Manage Engine MIB browser.

And the field of Host, Port and Community are filled with 172.16.100.223, 161 and public respectively. Object ID is the node of SNMP MIBs, e.g. “.1.3.6.1.2.1.1.6.0” is system location and “.1.3.6.1.2.1.1.1.0” is system description.
