FOXMAN-UN is a Network Management System (NMS) that caters for the management of FOX61x and FOX51x Network Elements (NEs) in a given network. Since the Network Elements types utilize a proprietary interface (thus these NEs are termed foreign devices in the SNMP world), a simple but industry standardized protocol, SNMP, has been implemented in order to integrate these NEs into a heterogeneous network where there may be Higher Order Network Manager(s) in a Network Operational Centre (NOC). This is achieved through the use of an SNMP proxy agent, which acts as an application-gateway on behalf of these foreign devices and is available as a licensed option in FOXMAN-UN. By propagating NE alarms through SNMP, the surveillance of a network can be accomplished via a HLM.

SNMP is one of the most widely used network management protocols and it is supported by most Network Management Systems. The FOXMAN-UN proxy agent uses this protocol to send information to a Higher Level Manager (HLM) in the form of trap messages.

The HLM may use traversal operation, however only read operations against the SNMP proxy agent are supported.

The SNMP agent of FOXMAN-UN supports SNMP V1, V2c, and V3.
