Management Interfaces
The FOXMAN-UN accesses the NE via an Ethernet network (optical 1/10/40 GbE or electrical 10Base-T, 100Base-TX, 1000Base-T).
FOX61x NEs offer a connection to a dedicated Ethernet management interface of the core unit (CESM1, CESM2, CESM3), or via an in-band connection. The NE management communication is based on TCP/IP.

Please note: 
When using OSPF in the management network of FOX61x nodes make sure to configure the source IP addresses for the different applications on the “managementNetwork” access point of the FOX61x nodes. We recommend the use of loopback interfaces for this purpose.
If these source IP addresses remain unconfigured the FOXMAN-UN will not be able to assign some of the notifications received from FOX61x nodes to the correct node. This will result in messages of the type “Missing Multiple Notification Messages” in the FOXMAN-UN event log.
