Trap Setting

Context

A managed device sends a trap to the NMS so that the administrator can discover exceptions of the device. The NMS receives a trap from a managed device without confirmation.

NOTE:

The web platform supports 20 trap destination hosts. When the number of configured trap destination hosts exceeds that limited by the web platform, a dialog box is displayed indicating that the number of trap destination hosts reaches the maximum.

Procedure

  • Trap setting
    1. Choose System Management > SNMP > Trap Setting, as shown in Figure 17-26.

    2. Set SNMP Trap to Enable or Disable.
    3. Click the button next to the Source interface that sends trap messages text box to select an interface for sending Trap messages.
