packets from the SNMP Management Station. The SNMP Agent will inform the SNMP

Management Station of Events, device Status changes, or if the device encounters any

abnormalities such as a device reboot.

MIB: The MIB is a set of Managed Objects. The MIB deﬁ nes the attributes of the man-

aged objects including Names, Access Rights and Data types. Every SNMP Agent has its

own speciﬁ c MIB. The SNMP Management Station can Read/Write to the MIB Objects

based on its Management rights.

SNMP Management Station is the manager of SNMP Network while SNMP Agent is the

Managed Object. The information exchanged between SNMP Management Station

and SNMP Agent is exchanged through SNMP (Simple Network Management Protocol).

The relationship between the SNMP Management Station, SNMP Agent and MIB is

illustrated in the following ﬁ gure:

SNMP Versions

This Switch supports SNMP up to Version 3 and is compatible with SNMP Version 1

and SNMP Version 2c. The SNMP Versions used by the SNMP Management Station and

SNMP Agent should be the same in order for the SNMP Management Station and SNMP

Agent to communicate with each other correctly. You can select the Management

mode with proper security level to ﬁ t your application requirements.

SNMP Version 1: SNMP v1 uses Community Name Authentication. The Community

Name is used to deﬁ ne the relation between SNMP Management Station and SNMP

Agent. Any SNMP packets failing to pass the Community Name are discarded. The

community name can limit access to SNMP Agent from SNMP Management Station

functioning as a Password.
