Management Systems NMS agents and managed devices An NMS is the console through which the network administrator performs network management functions such as monitoring status e g alarm states and remote controlling of a set of managed devices One or more NMS s must exist on any managed network Generally the NMS is a computer running third party SNMP control software There are a number of third party SNMP software applications currently available on the market An NMS polls or communicates with an agent An agent is a network management software module that resides in a managed device An agent has local knowledge of management information and translates that information into a form compatible with SNMP The agent therefore acts as an interface between the NMS and the managed devices The NMS sends a request message and control commands for the managed devices to the agent which in turn sends a response message containing information about the managed devices back to the NMS A managed device contains an SNMP agent and resides on a managed network Managed devices collect and store management information and make this information available to NMS s using SNMP Managed device agent variables are organised in a tree structure known as a Management Information Base MIB Within the MIB are parameters pertaining to the managed device An Object Identifier OID number within the MIB defines the managed device type This is a uniqu
