SNMP framework
The SNMP framework contains the following elements:
SNMP manager—Works on an NMS to monitor and manage the SNMP-capable devices in the network.
SNMP agent—Works on a managed device to receive and handle requests from the NMS, and sends notifications to the NMS when events, such as an interface state change, occur.
Management Information Base (MIB)—Specifies the variables (for example, interface status and CPU usage) maintained by the SNMP agent for the SNMP manager to read and set.
