4.11 SNMP
Simple Network Management Protocol (SNMP) provides a method for managing network devices. Devices supporting SNMP
run a local software (agent).
The SNMP agents maintain a list of variables, which are used to manage the device. The variables are defined in the
Management Information Base (MIB). The MIB contains the variables controlled by the agent. The SNMP protocol defines the
MIB specification format, as well as the format used to access the information over the network.
Access rights to the SNMP agents are controlled by access strings. To communicate with the device, the Embedded Web
Server submits a valid community string for authentication.
