SNMP Trap Manager Setting

Enables you to enter the IP addresses of Trap Managers. Traps are messages the DES- 5016 sends out to inform trap managers of events on the network. The DES-5016 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-5016 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-5016 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-5016 is not a valid user of the DES-5016 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.

Status

The DES-5016 will not send out traps unless the status is Valid.
