Juniper Netscreen 5400 firewalls do not implement the ipAddrTable. While OpenNMS is able to discover the SNMP service and collect node-level performance data from these devices, it's impossible (using Capsd) to collect interface data, and each interface on a Netscreen 5400 will tend to show up as if it were a separate node.
There is a partial workaround for this issue, which Juniper confirms as a "limitation" of the Netscreen devices. Create a provisioning group in OpenNMS, add a node for each Netscreen 5400, add all the IP interfaces to each node that belong to that node, and put the SNMP service on the appropriate management interface. The multiple-node issue will be avoided by this approach, and interface-level data collection may work as well.
