2Running Head: Network Management SolutionIntroduction A network management solution facilitates the proactive management of devices found in a network. It allows the devices in the network to be constantly queried for configuration and performance. This can be done using SNMP (Simple Network Management Protocol) together with MIB (Management Information Base). SNMP refers to an application layer protocol that allows information to be exchanged between devices in a network[ CITATION Ruf13 \l 1033 ]. The MIB on the other hand refers to a database that contains information describing the parameters ofa device in the network. The MIB contains standard control values for the hardware of the managed devices in the network[ CITATION Hel09 \l 1033 ]. The SNMP utilizes this database to request for information about a managed device and translates this information as required by thenetwork management system. Below is a scenario design of a network management solution together with its implementation that makes use of SNMP manager and MIB database for management of devices in a network.Scenario Design of a Network Management SolutionThe design of a network management solution will largely be dependent on the five areas of functionality as defined by the International Organization of Standards body. These areas includefault management, configuration management, performance management, security management and accounting management[ CITATION Cis07 \l 1033 ].Fault Management is concerned with the detection, notification, isolation and correction of faults occurring within a managed device in a network.Configuration Management deals with the settings aspect of a device in the network, such as file management configuration and software management. This ensures the configuration parameters are checked to avoid incompatibility issues.Performance Management ensures the optimal levels of performance of a network. It is required to perform a routine check of the quality service and performance level of each networked device. Security Management goal is to prevent and protect intentional or unintentional sabotage of the network by controlling access by the users in that network.Accounting Management refers to the process of regulating the utilization parameters of a network to maintain an optimal level of performance. This way, individuals and groups can be allocated network resources according to their usage patterns.The Design of a Network Management System will contain the following.

Firstly, the router will be handling all the addressing of other networked devices. In this case, a class C addressing scheme is used where the available ip addresses range from 192.0.0.0 – 223.255.255.255. The router address is 192.0.0.1. The rest of the devices in the network will take an ip address within the remaining range. Secondly, the router will house the SNMP agent together with the MIB database. The SNMP agent is a software that collects data from the devices in the network, stores it in the MIB and makes it available for the manager. The SNMP interacts with the agents using different types of commands, namely Read, Write, Notification. Using Read command, the SNMP manager reads MIB objects availed by the SNMP agents. Using Write command, the SNMP manager can modify the MIB objects and object instances stored the by the agents in the database. The read and write access is achieved by a concept known as Community strings. Community Strings act as passwords that allow authorized users only to get access to the agent. By default, the community strings are set to public which only authorizes a read-only access. The Notification command allows the SNMP manager to be issued with reports regarding a device state on the network. The SNMP agent makes use of traps to send notifications. On the other hand, MIB will contain the data from the devices that is shared between the networked device and the manager software.Network Management System (NMS)The network management system is a management console installed with a network monitoring software with built-in SNMP. The SNMP employs a client-server kind of communication where a request is sent by the NMS to the managed devices which in turn return a response. The SNMPuses four most common request operations. Get, GetNext, Trap and Set. Get is used to retrieve an instance of an object from the agent. GetNext retrieves the next instance of an object from a list or a table within the agent. GetNext operation reads through the table until all elements are retrieved indicated when the request returns a value outside of the list. Set operation is used to modify values of objects in the agent. Trap operation allows the agent to send notifications to theSNMP manager asynchronously during the occurrence of some event. The NMS takes the ip address 192.168.0.20 in the network. It communicates with the agent that provides data – either performance or configuration data - from the devices in the network.
