Traps are messages the DES-5200 sends out to inform trap managers of events on the network. The DES5200 generates traps and sends them to the network manager. Trap managers are special network users who are given certain rights and access to oversee and maintain the network. This feature is available only in D-View or by using other SNMP management software. You can specify which network managers may receive traps from the DES-5200 by creating a list of IP Addresses of the authorized network managers. Trap managers can receive the following trap types: · Cold Start · Authentication Failure · Link Change Event Cold Start Signifies that the DES-5200 has been powered up. Software settings are reconfigured and hardware systems are rebooted. A cold start is different from a factory reset. Authentication Failure Signifies that an addressee (or manager/ user) on the DES-5200 is not a valid user of the DES-5200 and may have entered an incorrect community name. Link Change Event Signifies that the link of a port has changed from link up to link down or vice versa. IP Address This field is used to enter the IP Addresses of Trap Managers.
