Create Traps

Follow these steps:

1. Display the Add a Trap Configuration page:
   1. Select Administration from the NFA console menu.

      The Administration page opens.

   2. Select Alerts from the Administration page menu.

      The Trap Configuration page opens and displays a list of the current traps.

   3. Click Add.

      The Add a Trap Definition page opens.

2. Define the trap description and the interfaces that the trap monitors:
   • Description: Identification for the new trap. Include information about the protocol and threshold, such as ‘Microsoft SQL Monitor utilization above 65%.’
   • Select Interface or Select Interface Group: Link to an index of interfaces or interface groups, which you use to select which interfaces that the trap monitors.

     Note: If the associated interface or interface group is deleted after you deploy the trap, an "Unknown interface group error" will occur. To eliminate this error, associate the trap with a different interface or interface group.

3. (Optional) Create a Utilization-based trap by providing the following information:
   • Thresholds: Utilization option: Setting to make the trap threshold type utilization. Use the context-sensitive fields that are added for this trap type.
   • Utilization: In field: Percentage of utilization that acts as the inbound threshold value
   • Utilization: In: minutes list: Number of minutes of inbound threshold violation that generates a trap
   • Utilization: Out field: Percentage of utilization that acts as the outbound threshold value
   • Utilization: Out: minutes list: Number of minutes of outbound threshold violation that generates a trap
   • Protocol: Protocol for the monitored traffic. Select the protocol in the Protocol Index dialog that opens. The trap will apply to the selected interfaces and protocol.
   • ToS: (Optional) Type of service (ToS) of the monitored traffic The trap will apply to the selected interfaces, protocol, and ToS. To monitor all ToS traffic, select All.
   • Time Filter: (Optional) Time period for monitoring if you choose to limit monitoring in this way. Select one of the available time filters from the list. The Time Filter list includes all the time filters that the Administrator created.
4. (Optional) Create a Rate-based trap by providing the following information:

   For example, suppose that you create a Rate-based trap and establish thresholds for both the inbound and outbound traffic. The trap is triggered when the threshold is met during the defined period.

   • Thresholds: Rate: Setting to base the trap threshold on data transfer rate. Use the context-sensitive fields that are added for this trap type.
   • Rate: In: Inbound data transfer speed that acts as a threshold value. Define the number of bits, kilobits, megabits, or gigabits per second, according to the unit of measurement selected.
   • Rate: Units of Measure: Unit of measurement for data transfer. Select bits per second (bps), kilobits per second (kbps), megabits per second (Mbps), or gigabits per second (Gbps).
   • Rate: In: minutes: Number of minutes of inbound threshold violation that generates a trap
   • Rate: Out: Threshold for outbound data transfer. Enter a number of bits, kilobits, megabits, or gigabits per second--according to the unit of measure for the inbound threshold.
   • Rate: Out: minutes: Number of minutes of outbound threshold violation that generates a trap
   • Protocol: Protocol for the monitored traffic. Select the protocol in the Protocol Index dialog that opens. The trap will apply to the selected interfaces and protocol.
   • ToS: (Optional) Type of service (ToS) of the monitored traffic The trap will apply to the selected interfaces, protocol, and ToS. To monitor all ToS traffic, select All.
   • Time Filter: (Optional) Time period for monitoring if you choose to limit monitoring in this way. Select one of the available time filters from the list. The Time Filter list includes all the time filters that the Administrator created.
5. (Optional) Create a Volume-based trap by providing the following information:
   • Thresholds: Volume: Setting to base the trap threshold on data volume. Use the context-sensitive fields that are added for this trap type.
   • Volume: In: Inbound data volume that acts as a threshold. Define the number of bytes, kilobytes, megabytes, gigabytes, or terabytes, according to the unit of measurement selected.
   • Volume: Units of Measure: Unit of measurement for data transfer. Select bytes, kilobytes (kB), megabytes (MB), gigabytes (GB), or terabytes (TB).
   • Volume: Out: Inbound data volume that acts as a threshold. Enter a number of bytes, kilobytes, megabytes, gigabytes, or terabytes--according to the unit of measure for the inbound threshold.
   • Volume: Out: minutes: Number of minutes of outbound threshold violation that generates a trap.
   • Protocol: Protocol for the monitored traffic. Select the protocol in the Protocol Index dialog that opens. The trap will apply to the selected interfaces and protocol.
   • ToS: (Optional) Type of service (ToS) of the monitored traffic The trap will apply to the selected interfaces, protocol, and ToS. To monitor all ToS traffic, select All.
   • Time Filter: (Optional) Time period for monitoring if you choose to limit monitoring in this way. Select one of the available time filters from the list. The Time Filter list includes all the time filters that the Administrator created.
6. (Optional) Create a Flow-based trap by providing the following information:
   • Thresholds: Flows: Setting to base the trap threshold on the number of flows. Use the context-sensitive fields that are added for this trap type.
   • Flows: Total: Number of inbound flows that acts as a threshold value. Define the number by flows per minute, thousands of flows per minute, or millions of flows per minute, according to the unit of measurement selected.
   • Flows: Units of Measure: Unit of measurement for data transfer. Select flows/minute, thousands of flows/minute, or millions of flows/minute.
   • Flows: minutes: Number of minutes of threshold violation that generates a trap
   • Time Filter: (Optional) Time period for monitoring if you choose to limit monitoring in this way. Select one of the available time filters from the list. The Time Filter list includes all the time filters that the Administrator created.
7. Click Submit when the selections are complete.

   The trap is deployed.

   Note: Traps are sent to the destination that is defined in the application settings.

To delete a trap definition, click the trap description in the Trap Configuration page trap list. Click the Delete button that appears in Edit mode. Verify the deletion when prompted.

To edit a trap definition, click the trap description in the Trap Configuration page trap list. Make updates in the Trap Configuration page in Edit mode. Click Submit. The trap is updated.
