Configure DNS/DHCP Server to send SNMP Trap notifications to a specified trap server.

The trap server is the server to which DNS/DHCP Server communicates specified changes in its status by sending SNMP traps. Multiple trap servers can be configured to use SNMP version 1, 2c, or 3. This may be a different address from the SNMP polling server or manager address that is set up when enabling the service. In SNMPv3, trap messages must be authenticated with a trap server username and password.
Note: Address Manager supports SNMP Traps with Anycast. For more information, refer to SNMP Traps with Anycast.

To configure SNMP Trap service on DNS/DHCP Server:

  1. From the configuration drop-down menu, select a configuration.
  2. Select the Servers tab. Tabs remember the page you last worked on, so select the tab again to ensure you're on the Configuration information page.
  3. Under Servers, click a server name. The Details tab for the server opens.
  4. Click the server name menu and select Service Configuration. The Configure Remote Services page opens.
  5. From the Service Type drop-down menu, select Simple Network Management Protocol (SNMP). Address Manager queries the server and returns the current values for the service settings.
    Attention: If you have upgraded from Address Manager v3.7.x, you will receive the following warning message:
    • This service has been set to Override. Any update to the service will overwrite the existing service configuration with the settings added in the user interface.

    Modifying the current service configuration will disable the Service Configuration Override and overwrite the existing configuration file with the new values and settings.

    Click Cancel to preserve the service configuration files maintained during the upgrade from Address Manager v3.7.x.

  6. Under SNMP Trap Settings, click New and select Trap Server.
  7. In the pop-up window, configure the following SNMP trap server parameters:
    • Trap Server—enter the IPv4 or IPv6 address of the trap server.

    • Trap Server Port—specify the value of the SNMP trap server port.
      Attention: The port value must be between 1 and 65534.
