Abstract: Based on SNMP protocol and component assembly technology, building network equipment simulation model to reflect the true operational status of ectuipment_ We can get or set the device operating status with the SNMP protocol, such as to get running status of CPU, memory and power supply. We can get an overall visual simulation model by the use of component assembly technology to assemble the network devices components, network ectuipment components including the engine board, business board,power and fan components, etc. hhe operation of these components de- pends on SNMP protocol. The simulation model of network ectuipment can improve the network management efficiency.The operation on simulation model is equivalent to operate the true equipment.
