SNMP Settings 

Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) 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, switch group or network. 

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
