System > SNMP Settings > SNMP Global State

Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) protocol designed

specifically for managing and monitoring network devices. SNMP enables network management stations to

read and modify the settings of gateways, routers, switches, and other network devices. Use SNMP to

configure system features for proper operation, monitor performance and detect potential problems in the

Switch or LAN.

Managed devices that support SNMP include software (referred to as an agent), which runs locally on the

device. A defined set of variables (managed objects) is maintained by the SNMP agent and used to manage

the device. These objects are defined in a Management Information Base (MIB), which provides a standard

presentation of the information controlled by the on-board SNMP agent. SNMP defines both the format of the

MIB specifications and the protocol used to access this information over the network.

The default SNMP global state is disabled. Select Enable and click Apply to enable the SNMP function.

System > SNMP Settings > SNMP User Table

This page is used to maintain the SNMP user table for the use of SNMPv3. SNMPv3 allows or restricts users

using the MIB OID, and also encrypts the SNMP messages sent out between users and Switch.
