See sectionConfiguring Basic SNMP Functions.z The configuration of adding “interface description” and “interface type” into alinkUp/linkDown trap is added. See section Configuring Extended Trap Function.1.1 SNMP OverviewThe Simple Network Management Protocol (SNMP) is used for ensuring thetransmission of the management information between any two network nodes. In thisway, network administrators can easily retrieve and modify the information about anynode on the network. In the meantime, they can locate faults promptly and implementthe fault diagnosis, capacity planning and report generating.As SNMP adopts the polling mechanism and provides basic function set, it is suitablefor small-sized networks with fast-speed and low-cost. SNMP is based on UserDatagram Protocol (UDP) and is thus widely supported by many products.1.1.1 SNMP Operation MechanismSNMP is implemented by two components, namely, network management station(NMS) and agent.z An NMS can be a workstation running client program. At present, the commonlyused network management platforms include QuidView, Sun NetManager, IBMNetView, and so on.z Agent is server-side software running on network devices (such as switches).
