SNMP Trap Manager Setting

Enables you to enter the IP addresses of Trap Managers. Traps are messages the DES-3216 sends out to inform trap managers of events on the network. The DES-3216 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-3216 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

Authentication Failure

Link Change Event

Signifies that the link of a port has changed from link up to link down or vice versa.
