2.6 SNMP

Any Network Management System (NMS) running the Simple Network Management Protocol (SNMP) can manage the managed devices equipped with SNMP agent, provided that the Management Information Base (MIB) is installed correctly on the managed devices. The SNMP is a protocol that is used to govern the transfer of information between SNMP manager and agent and traverses the Object Identity (OID) of the management Information Base (MIB), described in the form of SMI syntax. SNMP agent is running on the switch to responsd to the request issued by SNMP manager.

Essentially, SNMP is passive except for issuing the trap information. The switch supports a switch to turn on or off the SNMP agent. If you set the field SNMP “Enable”, SNMP agent will start. All supported MIB OIDs, including RMON MIB, can be accessed via SNMP manager. If the field SNMP is set “Disable,” SNMP agent will be de-activated, the related Community Name, Trap Host IP Address, Trap, and all MIB counters will be ignored.

2.6.1 System

This section describes how to configure SNMP System on the switch. This function is used to configure SNMP settings, community name, trap host, and public traps as well as the throttle of SNMP. A SNMP manager must pass the authentication by identifying both community names, then it can access the MIB information of the target device. So, both parties must have the same community name. Once completing the setting, click the <Apply> button, and the setting takes effect.

Web Interface

To display the configure SNMP System in the Web interface:

1.Click SNMP, System.

2.Evoke SNMP State to enable or disable the SNMP function .
