The final step to managing networks of overlapping IP addresses is to configure the devices in each network to forward SNMP traps to the appropriate IP Manager. Devices should be configured to send SNMP traps to the IP address of the appropriate virtual interface used by the IP Manager. In our example, devices in Domain A are configured to send SNMP traps to the virtual interface used by IP Manager A.

The configuration of ’ trap processing is described in the IP Manager User Guide and the Service Assurance Manager Adapter Platform User Guide. A built-in trap receiver runs automatically as a process within each IP Manager.

If the configuration for both built-in trap receivers is the same, they can share the same trapd.conf configuration file. Because each IP Manager will listen for traps on different IP addresses, both IP Managers can listen on the same port.
